The "Not Found" error you're encountering when listing rules for Ory Oathkeeper could be due to a few reasons. Here are some things you can check: 1. Access Rules Repository Path: In your Oathkeeper configuration, you should have specified the location of your access rules under

access_rules.repositories

. Make sure the path you've provided is correct. For example, if your rules are stored in a local file, your configuration might look like this:

yaml access_rules:     repositories:       - <file://path/to/rules.json>

(Source: [Ory Documentation](https://www.ory.sh/docs/oathkeeper/configure-deploy#configure)) 2. Access Rules Format: The access rules file (e.g.,

rules.json

) should be formatted as a JSON or YAML array containing the access rules. Here's an example of what this might look like:

json [   {       "id": "my-first-rule"     },   {       "id": "my-second-rule"     } ]

(Source: [Ory Documentation](https://www.ory.sh/docs/oathkeeper/api-access-rules)) 3. Oathkeeper API Endpoint: If you're using the Oathkeeper CLI to list rules, make sure you're pointing to the correct Oathkeeper API endpoint. For example:

bash oathkeeper rules --endpoint=<http://localhost:4456/> list

(Source: [Ory Documentation](https://www.ory.sh/docs/oathkeeper/cli/oathkeeper-rules-list)) If you've checked all of these and you're still encountering issues, it might be helpful to look at the logs for more detailed error messages.

If you're running Ory Oathkeeper in a Kubernetes environment like Minikube, you need to ensure that the

access-rules.json

file is correctly mounted into the Oathkeeper pod. This is typically done using a Kubernetes ConfigMap or Secret, which is then mounted as a volume in your Oathkeeper deployment. Here's a general example of how you might define a ConfigMap and use it in a deployment:

yaml apiVersion: v1 kind: ConfigMap metadata:   name: oathkeeper-rules data:   access-rules.json: |     [       {         "id": "my-first-rule"       },       {         "id": "my-second-rule"       }     ]  ---  apiVersion: apps/v1 kind: Deployment metadata:   name: oathkeeper spec:   template:     spec:       containers:       - name: oathkeeper         image: oryd/oathkeeper:<version-you-want>         volumeMounts:         - name: rules-volume           mountPath: /etc/oathkeeper       volumes:       - name: rules-volume         configMap:           name: oathkeeper-rules

In this example, the

access-rules.json

file is defined in a ConfigMap named

oathkeeper-rules

, and this ConfigMap is mounted as a volume at

/etc/oathkeeper

in the Oathkeeper container. Please replace

<version-you-want>

with the version of Ory Oathkeeper you are using. If you've done this and you're still encountering issues, it might be helpful to check the logs of the Oathkeeper pod for more detailed error messages. You can do this with the command

kubectl logs <pod-name>

, replacing

<pod-name>

with the name of your Oathkeeper pod. Please note that the above is a general example and might need to be adjusted to fit your specific Kubernetes setup.

If you don't see any logs related to the rules being loaded, it could be due to a few reasons: 1. Log Level: Ory Oathkeeper might not be set to a log level that includes informational messages about loading rules. You can adjust the log level by setting the

LOG_LEVEL

environment variable in your Oathkeeper deployment. For example, you might set

LOG_LEVEL=debug

to enable debug logs. 2. Rule File Format: Ensure that your

access-rules.json

file is correctly formatted as a JSON array of rule objects. If the file is not correctly formatted, Oathkeeper might not be able to load the rules. 3. File Path: Double-check the file path you've provided in your Oathkeeper configuration. In a Kubernetes environment, the file path should be the path where your

access-rules.json

file is mounted in the Oathkeeper container. If you've checked all of these and you're still not seeing any logs about rules being loaded, there might be an issue with how Oathkeeper is starting up. You can try to debug this by looking at the logs from when the Oathkeeper pod starts. You can get these logs with the command

kubectl logs <pod-name>

, replacing

<pod-name>

with the name of your Oathkeeper pod. If you're still having trouble, it might be helpful to share the exact error message you're seeing, or any other relevant logs or configuration details.

Sorry @damp-eye-52281, I seem to be having a bit of trouble. Don't worry though, I've pinged my support folks and they will try to fix me up! 🧑‍💻 Perhaps try again in 5mins?

A message from kapa.ai

If you're not seeing any logs related to rules loading in Ory Oathkeeper, it's possible that there might be an issue with the configuration or the way the application is starting up. Here are a few things you can check: 1. Log Level: Make sure that the log level is set to a level that includes informational messages. You can set the log level by adding an environment variable

LOG_LEVEL

in your Oathkeeper deployment and setting it to

info

or

debug

. 2. Access Rules Configuration: Double-check your access rules configuration in the Oathkeeper config file. Make sure the path to your

access-rules.json

file is correct. The configuration should look something like this:

yaml access_rules:     repositories:       - file:///etc/oathkeeper/access-rules.json

3. Access Rules File: Ensure that your

access-rules.json

file is correctly formatted as a JSON array of rule objects. If the file is not correctly formatted, Oathkeeper might not be able to load the rules. 4. File Permissions: Check the permissions of the

access-rules.json

file. Ory Oathkeeper needs to have read access to the file. 5. Oathkeeper Startup: Look at the logs from when the Oathkeeper pod starts. There might be some error messages or warnings that could give you a clue about what's going wrong. If you've checked all of these and you're still not seeing any logs about rules being loaded, it might be a more complex issue that requires a deeper investigation. In that case, you might want to reach out to the Ory community or support for more help.

The output you're seeing indicates that

access-rules.json

is a symbolic link (symlink) to another file,

..data/access-rules.json

. This is a common pattern in Kubernetes, where a ConfigMap or Secret is mounted as a volume in a pod. The permissions

lrwxrwxrwx

mean that the symlink is readable, writable, and executable by all users. However, the permissions of the symlink don't necessarily reflect the permissions of the file it points to. To check the permissions of the actual file, you can use the

ls -l

command on the target of the symlink, like so:

bash ls -l ..data/access-rules.json

This will show you the permissions of the actual

access-rules.json

file. Ory Oathkeeper needs to have read access to this file in order to load the access rules. If Ory Oathkeeper still can't read the file, there might be an issue with the way the volume is mounted in the Oathkeeper pod. You might need to check your Kubernetes deployment configuration to make sure the volume mount is set up correctly.

Your configuration seems correct at first glance. You have correctly defined the access rules in a ConfigMap and specified the path to these rules in the Ory Oathkeeper configuration. However, there's one thing that might be causing an issue. In your access rule, the

url

field in the

match

object is enclosed in

<

and

>

brackets. These brackets are used when you want to use a regular expression or glob pattern to match the URL. If you want to match a specific URL exactly, you should remove these brackets. Here's how your access rule should look:

json [   {     "id": "example-rule",     "match": {       "url": "<http://localhost/v1/vehicles>",       "methods": ["GET"]     },     "authenticators": [{"handler": "noop"}],     "authorizer": {"handler": "allow"},     "mutators": [{"handler": "noop"}]   } ]

If you've made this change and you're still encountering issues, it might be helpful to look at the logs for more detailed error messages. You can do this with the command

kubectl logs <pod-name>

, replacing

<pod-name>

with the name of your Oathkeeper pod. If you're still having trouble, it might be a more complex issue that requires a deeper investigation. In that case, you might want to reach out to the Ory community or support for more help.

Your Kubernetes Deployment and Service configuration for Ory Oathkeeper seems to be correctly set up. You have correctly defined the Deployment with the necessary environment variables, volume mounts, and container ports. The Service is also correctly set up to expose the necessary ports. However, similar to the previous issue, the

OAUTH2_INTROSPECT_URL

and

OAUTH2_ISSUER_URL

environment variables are enclosed in

<

and

>

brackets. These brackets are not necessary and should be removed. Here's how your environment variables should look:

yaml env:   - name: OAUTH2_INTROSPECT_URL     value: "<http://hydra:4445/oauth2/introspect>"  # Adjust as necessary   - name: OAUTH2_ISSUER_URL     value: "<http://hydra:4444>"  # Adjust as necessary   - name: LEAK_SENSITIVE     value: "true"   - name: LOG_LEVEL     value: debug

If you've made this change and you're still encountering issues, it might be helpful to look at the logs for more detailed error messages. You can do this with the command

kubectl logs <pod-name>

, replacing

<pod-name>

with the name of your Oathkeeper pod. If you're still having trouble, it might be a more complex issue that requires a deeper investigation. In that case, you might want to reach out to the Ory community or support for more help.

No, you should not need to point to

..data/rule.json

. In Kubernetes, when you mount a ConfigMap or Secret as a volume, Kubernetes creates a symlink for each file in the volume directory (

/etc/oathkeeper

in your case) that points to the actual file in the

..data

directory. This is done to handle updates to the ConfigMap or Secret. In your Ory Oathkeeper configuration, you should refer to the file as

/etc/oathkeeper/access-rules.json

, not

..data/access-rules.json

. The Kubernetes volume system will automatically ensure that

/etc/oathkeeper/access-rules.json

points to the correct file. If Ory Oathkeeper is not able to read the

access-rules.json

file, it's likely due to some other issue, not the file path. Please double-check the file permissions, the file format, and the Oathkeeper logs for any error messages.

Yes, Ory Oathkeeper provides several ways to load access rules: 1. File System: You can store access rules on the file system and provide the path to the file in the Oathkeeper configuration. This is what you're currently doing with the

access-rules.json

file. 2. Environment Variable: You can set access rules as an environment variable. The rules must be base64 encoded. Here's an example:

bash export ACCESS_RULES_REPOSITORIES='<file://path/to/rules.json,https://path-to-my-rules/rules.json,inline://W3siaWQiOiJmb28tcnVsZSIsImF1dGhlbnRpY2F0b3JzIjpbXX1d>'

3. HTTP(s) Remotes: You can fetch access rules from an HTTP or HTTPS remote. The remote must return a JSON or YAML array containing the access rules. Here's an example:

yaml access_rules:     repositories:       - <https://path-to-my-rules/rules.json>

4. Object Storage: You can fetch access rules from an object storage service like AWS S3, Google Cloud Storage, or Azure Blob Storage. Here's an example:

yaml access_rules:     repositories:       - <s3://my-bucket-name/rules.json>

Remember to configure the

access_rules

section in your Oathkeeper configuration to point to the location where your rules are stored ([source](https://www.ory.sh/docs/oathkeeper/api-access-rules)).

The log message you're seeing indicates that a GET request was made to the

/v1/vehicles

path, but Ory Oathkeeper returned a 404 Not Found response. This suggests that there's no access rule matching this request. Here are a few things you can check: 1. Access Rule Matching: Make sure you have an access rule that matches the

GET /v1/vehicles

request. The access rule should look something like this:

json {   "id": "example-rule",   "match": {     "url": "<http://localhost/v1/vehicles>",     "methods": ["GET"]   },   "authenticators": [{"handler": "noop"}],   "authorizer": {"handler": "allow"},   "mutators": [{"handler": "noop"}] }

2. Access Rule Loading: Make sure Ory Oathkeeper is correctly loading the access rules. You can check the Oathkeeper logs for any error messages related to loading the access rules. 3. Request Path: Make sure the request is being made to the correct path. The path in the request should match the path in the access rule. If you've checked all of these and you're still encountering issues, it might be a more complex issue that requires a deeper investigation. In that case, you might want to reach out to the Ory community or support for more help.

Ory Oathkeeper can be used as a gRPC middleware, which means it can handle gRPC traffic and forward it to your gRPC backend service. However, the specific configuration for this depends on the details of your setup. Here's a general example of how you might set up an access rule for a gRPC service:

json {   "id": "grpc-rule",   "match": {     "url": "<http://localhost:4455/my.grpc.package/MyService/MyMethod>",     "methods": ["POST"]   },   "authenticators": [{"handler": "noop"}],   "authorizer": {"handler": "allow"},   "mutators": [{"handler": "noop"}],   "upstream": {     "url": "<http://my-grpc-service:50051>"   } }

In this example, the

url

in the

match

object is the URL that Ory Oathkeeper listens on for incoming requests. The

url

in the

upstream

object is the URL of your gRPC service. Please note that this is a general example and might need to be adjusted to fit your specific setup. For example, you might need to adjust the

url

and

methods

in the

match

object, or the

url

in the

upstream

object, depending on the details of your gRPC service. For more information on how to use Ory Oathkeeper with gRPC, you can refer to the [Ory Oathkeeper gRPC middleware documentation](https://www.ory.sh/docs/oathkeeper/grpc-middleware).

The error message "unsupported protocol scheme 'grpc'" suggests that Ory Oathkeeper is not able to handle the 'grpc' protocol scheme. This is because Ory Oathkeeper's reverse proxy currently only supports HTTP/HTTPS upstreams. While Ory Oathkeeper can be used as a gRPC middleware, it does not support forwarding requests to a gRPC upstream via the reverse proxy. The gRPC middleware feature allows you to embed Ory Oathkeeper into your Go application, and the gRPC traffic will be handled by the middleware as if it were a standalone Ory Oathkeeper instance. If you want to use Ory Oathkeeper with a gRPC service, you would need to embed Ory Oathkeeper into your Go application as a gRPC middleware. Here's an example of how you might do this:

go import (    "<http://github.com/ory/oathkeeper/middleware|github.com/ory/oathkeeper/middleware>"    "<http://google.golang.org/grpc|google.golang.org/grpc>"   )      func setup() {    oathkeeperMW, err := middleware.New(ctx, middleware.WithConfigFile("path/to/config"))    if err != nil {     return nil, nil, fmt.Errorf("failed to create oathkeeper middleware: %w", err)    }        s := grpc.NewServer(     grpc.UnaryInterceptor(mw.UnaryInterceptor()),     grpc.StreamInterceptor(mw.StreamInterceptor()),    )        // register your service to s, start the server, ...   }

For more information on how to use Ory Oathkeeper as a gRPC middleware, you can refer to the [Ory Oathkeeper gRPC middleware documentation](https://www.ory.sh/docs/oathkeeper/grpc-middleware).

Your configuration for enabling

oauth2_introspection

in Ory Oathkeeper seems to be correct. You have correctly set the

enabled

field to

true

under

authenticators.oauth2_introspection

and provided the

introspection_url

. However, similar to the previous issue, the

introspection_url

is enclosed in

<

and

>

brackets. These brackets are not necessary and should be removed. Here's how your

oauth2_introspection

configuration should look:

yaml authenticators:   oauth2_introspection:     enabled: true     config:       introspection_url: "<http://hydra:4445/oauth2/introspect>"

If you've made this change and you're still encountering issues, it might be helpful to look at the logs for more detailed error messages. You can do this with the command

kubectl logs <pod-name>

, replacing

<pod-name>

with the name of your Oathkeeper pod. If you're still having trouble, it might be a more complex issue that requires a deeper investigation. In that case, you might want to reach out to the Ory community or support for more help.

Sure, here's an example of an access rule that uses the

oauth2_introspection

authenticator:

json {   "id": "some-id",   "upstream": {     "url": "<http://my-backend-service>"   },   "match": {     "url": "<http://my-app/some-route>",     "methods": ["GET"]   },   "authenticators": [{     "handler": "oauth2_introspection",     "config": {       "introspection_url": "<https://my-website.com/oauth2/introspection>",       "scope_strategy": "exact",       "required_scope": ["photo", "profile"],       "target_audience": ["example_audience"],       "trusted_issuers": ["<https://my-website.com/>"],       "pre_authorization": {         "enabled": true,         "client_id": "some_id",         "client_secret": "some_secret",         "scope": ["introspect"],         "token_url": "<https://my-website.com/oauth2/token>"       },       "token_from": {         "header": "Authorization"       },       "introspection_request_headers": {         "x-forwarded-proto": "https"       },       "retry": {         "max_delay": "300ms",         "give_up_after": "2s"       },       "cache": {         "enabled": true,         "ttl": "60s"       }     }   }],   "authorizer": {     "handler": "allow"   },   "mutators": [{     "handler": "noop"   }] }

In this example, the

oauth2_introspection

authenticator is used to validate the OAuth2 token in the

Authorization

header of the request. The token is introspected at the

introspection_url

, and the request is only allowed if the token is valid and has the required scope and audience. Please note that this is a general example and might need to be adjusted to fit your specific setup. For example, you might need to adjust the

introspection_url

,

required_scope

,

target_audience

, and other configuration options depending on your OAuth2 server's configuration. For more information on how to use the

oauth2_introspection

authenticator, you can refer to the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/pipeline/authn#oauth2_introspection).

The mandatory fields in the

oauth2_introspection

authenticator configuration are: - `handler`: This should be set to

oauth2_introspection

. - `config.introspection_url`: The OAuth 2.0 Token Introspection endpoint. The rest of the fields are optional and can be used to further customize the behavior of the

oauth2_introspection

authenticator. Here's a brief description of what each optional field does: - `config.scope_strategy`: Sets the strategy to be used to validate/match the token scope. Supports "hierarchic", "exact", "wildcard", "none". Defaults to "none". - `config.required_scope`: Sets what scope is required by the URL. - `config.target_audience`: Sets what audience is required by the URL. - `config.trusted_issuers`: Sets a list of trusted token issuers. - `config.pre_authorization`: Enable pre-authorization in cases where the OAuth 2.0 Token Introspection endpoint is protected by OAuth 2.0 Bearer Tokens. - `config.token_from`: The location of the bearer token. If not configured, the token will be received from a default location - 'Authorization' header. - `config.introspection_request_headers`: Additional headers to add to the introspection request. - `config.retry`: Configure the retry policy. - `config.cache`: Enables caching of incoming tokens. For more information on how to use the

oauth2_introspection

authenticator, you can refer to the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/pipeline/authn#oauth2_introspection-configuration).

The

introspection_url

you've set in the

oauth2_introspection

authenticator configuration should be the URL that Ory Oathkeeper uses to introspect the token. If Ory Oathkeeper is calling

<http://localhost:4445/admin/oauth2/introspect>

instead of

<http://hydra:4445/oauth2/introspect>

, it suggests that there might be an issue with your configuration or setup. Here are a few things you can check: 1. Configuration File: Make sure you're editing the correct configuration file and that Ory Oathkeeper is using the updated configuration. You might need to restart Ory Oathkeeper for the changes to take effect. 2. Configuration Syntax: Make sure the configuration syntax is correct. The

introspection_url

should be a string and should not be enclosed in

<

and

>

brackets. Here's how your configuration should look:

json {   "handler": "oauth2_introspection",   "config": {     "introspection_url": "<http://hydra:4445/oauth2/introspect>"   } }

3. Environment Variables: If you're using environment variables to set the

introspection_url

, make sure the environment variable is correctly set and is being picked up by Ory Oathkeeper. If you've checked all of these and you're still encountering issues, it might be a more complex issue that requires a deeper investigation. In that case, you might want to reach out to the Ory community or support for more help.

The error message "Access credentials are invalid" and "Access token is not active" typically means that the access token used in the request is either expired, revoked, or not valid for some other reason. Here are a few things you can check: 1. Token Expiry: Access tokens have a limited lifespan, which is typically short for security reasons. If the token is expired, you'll need to obtain a new one. 2. Token Revocation: If the token was revoked before it expired, it will be considered inactive. This could happen if, for example, the user logged out, changed their password, or if the token was manually revoked for some reason. 3. Token Validation: The token might be malformed, not signed by the expected issuer, or not meant for the intended audience. Make sure the token was issued by the correct OAuth2 server, and that it's intended for the audience (

aud

) that you're trying to use it with. You can use the OAuth2 Token Introspection endpoint to check the active status and other details of the token. Here's an example of how to do this using the Ory SDK:

javascript import { Configuration, OAuth2Api } from "@ory/client"  const ory = new OAuth2Api(   new Configuration({     basePath: `https://${process.env.ORY_PROJECT_SLUG}.<http://projects.oryapis.com|projects.oryapis.com>`,     accessToken: process.env.ORY_API_KEY,   }), )  export async function introspectToken(accessToken: string) {   const { data } = await ory.introspectOAuth2Token({ token: accessToken })   console.log(data.active) // true or false }

Replace

accessToken

with the actual access token you're trying to validate. This will print

true

if the token is active, or

false

if it's not ([source](https://www.ory.sh/docs/hydra/guides/oauth2-token-introspection)). If you're still having issues, you might want to check the server logs for more detailed error messages, or reach out to the Ory community or support for more help.

If Ory Oathkeeper is not sending the default response for an invalid token, it might be due to the error handling configuration in your setup. Ory Oathkeeper allows you to set up custom error handlers that can be used to customize the response when an error occurs. Here's an example of how you might set up an error handler to return a JSON response:

yaml errors:   handlers:     json:       enabled: true

In this example, the

json

error handler is enabled, which means Ory Oathkeeper will return a JSON response when an error occurs. If you want to customize the error message for an invalid token, you can do so by setting up a custom error handler and using the

message

field to set the error message. Here's an example:

yaml errors:   handlers:     json:       enabled: true       config:         message: "Invalid token"

In this example, Ory Oathkeeper will return a JSON response with the message "Invalid token" when an error occurs. For more information on how to set up error handlers in Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/pipeline/error).

Sure, here's an example of how you might structure an error response for invalid credentials in JSON:

json {   "id": 4000006,   "text": "The provided credentials are invalid, check for spelling mistakes in your password or username, email address, or phone number.",   "type": "error" }

In this example, the

id

field is a unique identifier for the error, the

text

field is a human-readable message that describes the error, and the

type

field indicates that this is an error message. This is based on the error message format used by Ory Kratos, as described in the [Ory Kratos documentation](https://www.ory.sh/docs/kratos/concepts/ui-messages#the-provided-credentials-are-invalid-check-for-spelling-mistakes-in-your-password-or-username-email-address-or-phone-number-4000006).

The provided JSON configuration for the error handler seems to be correct. It specifies that the

json

error handler should be used and that a custom message "Access denied due to invalid or expired token." should be returned when an error occurs. The

when

field specifies that this handler should be used when the error is either

unauthorized

,

invalid_token

, or

token_expired

. Here's the formatted JSON for clarity:

json {   "errors": [     {       "handler": "json",       "config": {         "message": "Access denied due to invalid or expired token.",         "when": [           {             "error": ["unauthorized", "invalid_token", "token_expired"]           }         ]       }     }   ] }

Please note that

invalid_token

and

token_expired

are not standard HTTP status messages. The standard HTTP status messages are derived (lowercase and whitespaces replaced with

_

) from the well-defined [HTTP Status](https://en.wikipedia.org/wiki/List_of_HTTP_status_codes) messages such as

Not Found

,

Forbidden

,

Internal Server Error

, and so on. If Ory Oathkeeper is configured to emit these specific error types (

invalid_token

,

token_expired

), then this configuration should work as expected. For more information on how to set up error handlers in Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/pipeline/error).

The error message "additional property message is not allowed" suggests that the

message

field is not a recognized configuration option for the

json

error handler in Ory Oathkeeper. The

json

error handler in Ory Oathkeeper does not support a

message

field in its configuration. Instead, it automatically generates error messages based on the type of error that occurred. Here's an example of a valid

json

error handler configuration:

json {   "errors": [     {       "handler": "json",       "config": {}     }   ] }

In this example, the

json

error handler is enabled, and no additional configuration is provided. This means that Ory Oathkeeper will use the default error messages. If you want to customize the error messages, you would need to implement a custom error handler. For more information on how to do this, you can refer to the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/pipeline/error).

A message from kapa.ai

Sure, here's an example of an Ory Oathkeeper configuration snippet related to operations:

yaml serve:   proxy:     port: 4455     cors:       enabled: false       allowed_origins: ["*"]       allowed_methods: ["GET", "POST", "PUT", "PATCH", "DELETE"]       allowed_headers: ["Authorization", "Content-Type"]       exposed_headers: ["Content-Type"]       max_age: 0       allow_credentials: false     timeout:       idle: 120s       read: 5s       write: 120s     trust_forwarded_headers: false    api:     port: 4456     cors:       enabled: false       allowed_origins: ["*"]       allowed_methods: ["GET", "POST", "PUT", "PATCH", "DELETE"]       allowed_headers: ["Authorization", "Content-Type"]       exposed_headers: ["Content-Type"]       max_age: 0       allow_credentials: false     timeout:       idle: 120s       read: 5s       write: 120s    prometheus:     port: 9000     metrics_path: "/metrics"     metric_name_prefix: "ory_oathkeeper_"     collapse_request_paths: true     hide_request_paths: false

This configuration snippet sets up the ports, CORS settings, timeouts, and Prometheus metrics for the Ory Oathkeeper proxy and API servers. For more information on how to configure Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/reference/configuration).

I'm sorry, but the provided knowledge sources do not contain any information or examples related to Open Policy Agent (OPA) configuration for Ory. Ory's main components like Ory Kratos, Ory Hydra, and Ory Keto have their own specific configurations and do not directly mention OPA. For information on how to configure OPA with Ory or any other system, you would typically refer to the specific documentation of that system or the [OPA documentation](https://www.openpolicyagent.org/docs/latest/). If you have any other questions about Ory's configuration, feel free to ask!

The error message indicates that the

authorizer.handler

in your rule is set to

"opa"

, which is not recognized as a valid authorizer by Ory Oathkeeper. Ory Oathkeeper supports different kinds of authorizers, and the list of supported authorizers can increase over time due to new features and requirements. However, based on the provided knowledge sources, the supported authorizers include

noop

,

allow

,

deny

, and

keto_engine_acp_ory

. Here's an example of how you might set the

authorizer.handler

to `allow`:

json {   "authorizer": {     "handler": "allow"   } }

In this example, the

allow

authorizer permits every action allowed. You should replace

"opa"

with a valid authorizer handler in your rule configuration. If you intended to use Open Policy Agent (OPA) for authorization, you would need to implement a custom authorizer or use an existing OPA integration if one is available. For more information on how to configure authorizers in Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/pipeline/authz).

Yes, once Ory Kratos is running in Minikube, you can access the Kratos UI from a browser. However, it's important to note that Ory Kratos itself is API-only and does not provide a user interface. You would need to set up your own user interface and configure it to use the Ory Kratos APIs. To access your UI (or any service) running in Minikube from a browser, you can use one of the following methods: 1. NodePort: Expose your service using a NodePort. This will make your service accessible on a static port on the Minikube VM. You can then access the service using the Minikube IP and the NodePort. Here's an example command to get the Minikube IP:

bash    minikube ip

2. Ingress: If you have the Ingress addon enabled in Minikube, you can set up an Ingress resource that routes traffic to your service. You can then access the service using the Minikube IP and the path defined in your Ingress resource. 3. Port Forwarding: You can use the

kubectl port-forward

command to forward a local port to a port on the Pod running your service. Here's an example command:

bash    kubectl port-forward pod/my-pod 8080:80

This will forward local port 8080 to port 80 on

my-pod

. You can then access the service at

localhost:8080

. Remember to replace

my-pod

with the name of the Pod running your service, and adjust the port numbers as necessary. For more information on how to set up and configure Ory Kratos, you can refer to the [Ory Kratos documentation](https://www.ory.sh/docs/kratos/).

Ory Kratos SelfService UI Node is a reference implementation of a user interface for Ory Kratos. It's built with Node.js and provides examples of how to implement registration, login, account verification, and more using the Ory Kratos APIs. Once you have Ory Kratos running in Minikube, you can also deploy the SelfService UI Node in the same Minikube cluster and configure it to use your Ory Kratos instance. Here's an example of how you might install the SelfService UI Node:

bash useradd -s /bin/false -m -d /opt/uinode uinode   cd /opt/uinode   wget <https://github.com/ory/kratos-selfservice-ui-node/archive/refs/tags/<version-you-want>.zip>   unzip <version-you-want>.zip   rm  <version-you-want>.zip   mv kratos-selfservice-ui-node-<version-you-want>/ ui   cd ui   npm i   chown -R uinode /opt/uinode

(Source: [Install Ory Kratos UI](https://www.ory.sh/docs/kratos/guides/deploy-kratos-example#install-ory-kratos-ui)) You would need to replace

<version-you-want>

with the version of the SelfService UI Node that you want to install. Once the SelfService UI Node is running, you can access it from a browser using one of the methods I described in the previous message (NodePort, Ingress, or Port Forwarding). Remember to configure the SelfService UI Node to use your Ory Kratos instance. You can do this by setting the

KRATOS_PUBLIC_URL

and

KRATOS_BROWSER_URL

environment variables to the URL of your Ory Kratos instance.

The

/self-service/registration/api

endpoint of Ory Kratos is designed to initiate a registration flow for API clients such as mobile devices, smart TVs, and so on. This endpoint does not return a

csrf_token

in the response. The

csrf_token

is used to protect against Cross-Site Request Forgery (CSRF) attacks and is typically used in browser-based flows where the client is a web browser. In API flows, CSRF protection is usually not necessary because API clients do not rely on cookies for session management. Here's an example of a response from the

/self-service/registration/api

endpoint:

json {   "id": "c7ed95c7-2710-436c-a7d0-09ac771a3e8b",   "type": "api",   "expires_at": "2021-07-09T10:41:34.883536226Z",   "issued_at": "2021-07-09T09:41:34.883536226Z",   "request_url": "<http://playground.projects.oryapis.com/self-service/registration/api>",   "ui": {     "action": "<https://playground.projects.oryapis.com/self-service/registration?flow=c7ed95c7-2710-436c-a7d0-09ac771a3e8b>",     "method": "POST",     "nodes": [ /* ... */ ]   } }

(Source: [Ory Kratos Documentation](https://www.ory.sh/docs/kratos/self-service/flows/user-registration#registration-for-api-clients-and-clients-without-browsers)) If you're working with a browser-based flow and need a

csrf_token

, you should use the

/self-service/registration/browser

endpoint instead. This endpoint will return a

csrf_token

in the

ui.nodes

array of the response. For more information on how to use the Ory Kratos APIs, you can refer to the [Ory Kratos API Reference](https://www.ory.sh/docs/kratos/reference/api).

The error message "Could not find any login identifiers. Did you forget to set them? This could also be caused by a server misconfiguration." indicates that Ory Kratos could not find any login identifiers in the request. Login identifiers are typically things like a username or email address that are used to identify a user. Here are a few things you can check: 1. Request Body: Make sure you're sending the correct login identifiers in your request. For example, if you're using the password method to authenticate, you should be sending a

password

and an

identifier

(which can be a username or email address) in your request. 2. Identity Schema: If you're using a custom identity schema, make sure you've marked the fields that should be used as identifiers. For example, if you want to allow both the username and email address for signing in, you should define

"identifier": true

for both

username

and

email

fields in your identity schema. Here's an example:

json    {      "<http://ory.sh/kratos|ory.sh/kratos>": {        "credentials": {          "password": {            "identifier": true          }        }      }    }

3. Server Configuration: If you're still encountering this error, it might be due to a server misconfiguration. Check your Ory Kratos configuration and make sure it's set up correctly. For more information on how to handle this error, you can refer to the [Ory Kratos documentation](https://www.ory.sh/docs/kratos/concepts/ui-messages#could-not-find-any-login-identifiers-did-you-forget-to-set-them-this-could-also-be-caused-by-a-server-misconfiguration-4000009).

The payload for registration depends on the identity schema you use. However, a typical payload for a registration request using the password method might look like this:

json {   "method": "password",   "csrf_token": "<your-csrf-token>",   "traits.email": "<user-email>",   "password": "<user-password>",   "traits.tos": "<true-or-false>" }

Here's a breakdown of what each field means: - `method`: This should be set to "password" to indicate that you're using the password method to authenticate. - `csrf_token`: This is a token used to protect against Cross-Site Request Forgery (CSRF) attacks. You can get this token from the

csrf_token

field in the response from the

/self-service/registration

endpoint. - `traits.email`: This is the email address of the user. The exact field name might be different depending on your identity schema. - `password`: This is the password of the user. - `traits.tos`: This is a boolean value indicating whether the user has agreed to the terms of service. The exact field name might be different depending on your identity schema. Here's an example of how you might send a registration request using `curl`:

bash curl -X POST \     -H 'Content-Type: application/json' \     -H 'Accept: application/json' \     -d '{"method":"password","csrf_token":"<your-csrf-token>","traits.email":"<user-email>","password":"<user-password>","traits.tos":"<true-or-false>"}' \     "https://$<http://PROJECT_SLUG.projects.oryapis.com/self-service/registration?flow=<your-flow-id|PROJECT_SLUG.projects.oryapis.com/self-service/registration?flow=<your-flow-id>>"

Remember to replace

<your-csrf-token>

,

<user-email>

,

<user-password>

,

<true-or-false>

, and

<your-flow-id>

with your actual values. For more information on how to handle registration with Ory Kratos, you can refer to the [Ory Kratos documentation](https://www.ory.sh/docs/kratos/self-service/flows/user-registration).

The error message you're seeing is due to a mismatch between the type of request Ory Kratos is expecting and the type of request it received. When initiating a flow, Ory Kratos distinguishes between API clients (like mobile apps) and browser clients. API clients should use the

/self-service/{flow-type}/api

endpoint, while browser clients should use the

/self-service/{flow-type}/browser

endpoint. The error message indicates that the request was made to an API endpoint (like

/self-service/{flow-type}/api

), but the presence of the

Cookie

header suggests that the request was made by a browser. This is considered a potential security risk and is therefore blocked by Ory Kratos. To resolve this issue, you should ensure that: - Browser clients (like a web app) use the

/self-service/{flow-type}/browser

endpoint. - API clients (like a mobile app) use the

/self-service/{flow-type}/api

endpoint and do not include a

Cookie

header in the request. Here are the relevant sections from the Ory Kratos documentation: - [Browser vs. native apps](https://www.ory.sh/docs/identities/native-browser) - [Login for API Clients and Clients without Browsers](https://www.ory.sh/docs/kratos/self-service/flows/user-login#login-for-api-clients-and-clients-without-browsers) - [Registration for API clients and clients without browsers](https://www.ory.sh/docs/kratos/self-service/flows/user-registration#registration-for-api-clients-and-clients-without-browsers)

The error message "Could not find any login identifiers. Did you forget to set them?

The API endpoint you're using (`http://127.0.0.1:4433/self-service/registration/api`) is designed for API clients such as mobile devices, smart TVs, and so on. It does not use HTTP redirects and does not provide a CSRF token in the response. If you're working with a browser-based client (like a web app), you should use the

/self-service/registration/browser

endpoint instead. This endpoint initiates a registration flow for browser clients and includes a CSRF token in the response. Here's an example of how you might initiate a registration flow for a browser client:

bash curl -s -i -X GET \     -H "Accept: text/html" \     <http://127.0.0.1:4433/self-service/registration/browser>

In the response, you should see a

Set-Cookie

header with a

csrf_token

. This is the CSRF token you can use for subsequent requests. For more information on how to handle registration with Ory Kratos, you can refer to the [Ory Kratos documentation](https://www.ory.sh/docs/kratos/self-service/flows/user-registration#initialize-registration-flow).

Yes, you can integrate Open Policy Agent (OPA) with Ory Oathkeeper using the

remote_json

authorizer. Your configuration would look something like this:

yaml authorizers:   remote_json:     enabled: true     config:       remote: "<http://opa-service.default.svc.cluster.local/v1/data/example/authz>"       headers:         Content-Type: "application/json"

This configuration tells Ory Oathkeeper to use the

remote_json

authorizer, which makes a HTTP POST request to the specified remote endpoint (

<http://opa-service.default.svc.cluster.local/v1/data/example/authz>

in this case) with a JSON body. If the endpoint returns a "200 OK" response code, the access is allowed. If it returns a "403 Forbidden" response code, the access is denied. You can also specify additional configuration options like

payload

and

forward_response_headers_to_upstream

if needed. Here's an example of how you might use the

payload

option to send additional data to the OPA service:

yaml authorizers:   remote_json:     enabled: true     config:       remote: "<http://opa-service.default.svc.cluster.local/v1/data/example/authz>"       headers:         Content-Type: "application/json"       payload: |         {           "input": {             "subject": "{{ print .Subject }}",             "resource": "{{ printIndex .MatchContext.RegexpCaptureGroups 0 }}"           }         }

In this example, the

payload

is a JSON object that includes the subject and resource from the request. For more information on how to configure the

remote_json

authorizer, you can refer to the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/pipeline/authz#remote_json). Sources: - [Oathkeeper > Pipeline > Authorizers >

Sure, here is the equivalent JSON configuration for integrating Open Policy Agent (OPA) with Ory Oathkeeper using the

remote_json

authorizer:

json {   "authorizers": {     "remote_json": {       "enabled": true,       "config": {         "remote": "<http://opa-service.default.svc.cluster.local/v1/data/example/authz>",         "headers": {           "Content-Type": "application/json"         }       }     }   } }

And here is an example with the

payload

option to send additional data to the OPA service:

json {   "authorizers": {     "remote_json": {       "enabled": true,       "config": {         "remote": "<http://opa-service.default.svc.cluster.local/v1/data/example/authz>",         "headers": {           "Content-Type": "application/json"         },         "payload": {           "input": {             "subject": "{{ print .Subject }}",             "resource": "{{ printIndex .MatchContext.RegexpCaptureGroups 0 }}"           }         }       }     }   } }

Please note that the

payload

field is a string in the actual configuration file. The

{{ print .Subject }}

and

{{ printIndex .MatchContext.RegexpCaptureGroups 0 }}

are placeholders that will be replaced with actual values at runtime. For more information on how to configure the

I'm sorry, but I don't have enough information to provide a confident answer. The changes in a config map would depend on the specific context and the changes you've made. If you're referring to a Kubernetes ConfigMap, changes could include updates to the data field, metadata, or other properties. If you're referring to changes in the configuration of an Ory product, such as Ory Kratos or Ory Oathkeeper, the changes could include updates to the settings for various features or components. For more information on how to configure Ory products, you can refer to the respective documentation: - [Ory Kratos Configuration](https://www.ory.sh/docs/kratos/configuration) - [Ory Oathkeeper Configuration](https://www.ory.sh/docs/oathkeeper/configuration) For more information on Kubernetes ConfigMaps, you can refer to the [Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/configmap/).

The error message you're seeing indicates that the

remote_json

authorizer is disabled in your Ory Oathkeeper configuration. This means that any rules that use this authorizer will not work. To resolve this issue, you need to enable the

remote_json

authorizer in your Ory Oathkeeper configuration. Here's how you can do this: In your Ory Oathkeeper configuration file (usually named

oathkeeper.yml

), find the

authorizers

section and set

enabled

to

true

for the

remote_json

authorizer. Here's an example:

yaml authorizers:   remote_json:     enabled: true     config:       remote: "<http://my-remote-authorizer/authorize>"

In this example,

<http://my-remote-authorizer/authorize>

is the URL of your remote authorizer. Replace it with the actual URL of your remote authorizer. After making these changes, save your configuration file and restart Ory Oathkeeper. For more information on how to configure authorizers in Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/pipeline/authz).

configuration](https://www.ory.sh/docs/oathkeeper/pipeline/authz#remote_json-configuration)

The response you're seeing is likely from the Open Policy Agent (OPA) decision API. The

decision_id

is a unique identifier for the decision made by OPA. However, this response doesn't provide any information about the decision itself (whether access was allowed or denied). If you're expecting a different response, it could be due to how your OPA policy is written or how the request to OPA is being made. In the context of Ory Oathkeeper, when using the

remote_json

authorizer to integrate with OPA, OPA should return a response with a status code of "200 OK" to allow access, or "403 Forbidden" to deny access. The body of the response from OPA should be a JSON object with a boolean

allow

field. Here's an example of how OPA might respond to an authorization request:

json {   "result": {     "allow": true   } }

In this example, the

allow

field is

true

, which means access is allowed. If you're not seeing the expected response, you should check your OPA policy and the request you're sending to OPA. Make sure your policy is correctly written and that your request includes all the necessary information. For more information on how to integrate OPA with Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/pipeline/authz#remote_json).

remote_json

example](https://www.ory.sh/docs/oathkeeper/pipeline/authz#remote_json-example)

The

remote_json

authorizer in Ory Oathkeeper performs authorization based on the HTTP status code returned by the remote endpoint. If the endpoint returns a "200 OK" response code, the access is allowed. If it returns a "403 Forbidden" response code, the access is denied. While the

remote_json

authorizer does send a JSON payload to the remote endpoint and can include HTTP headers in the request, it does not validate the response body from the remote endpoint. It only checks the HTTP status code. Here's an example of how you might configure the

remote_json

authorizer:

yaml authorizers:   remote_json:     enabled: true     config:       remote: "<http://my-remote-authorizer/authorize>"       headers:         Content-Type: "application/json"       payload: |         {           "subject": "{{ print .Subject }}",           "resource": "{{ printIndex .MatchContext.RegexpCaptureGroups 0 }}"         }

In this example, the

payload

is a JSON object that includes the subject and resource from the request. The

headers

include the

Content-Type

header set to

application/json

. For more information on how to configure the

remote_json

authorizer, you can refer to the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/pipeline/authz#remote_json). Sources: - [Oathkeeper > Pipeline > Authorizers >

remote_json

example](https://www.ory.sh/docs/oathkeeper/pipeline/authz#remote_json-example)

The response codes from Open Policy Agent (OPA) itself are not directly controlled by Ory Oathkeeper. OPA's response codes are determined by the logic you define in your OPA policies. However, when integrating OPA with Ory Oathkeeper using the

remote_json

authorizer, Ory Oathkeeper interprets the HTTP status codes returned by the remote endpoint (in this case, OPA). If the endpoint returns a "200 OK" response code, Ory Oathkeeper allows the access. If it returns a "403 Forbidden" response code, Ory Oathkeeper denies the access. If you want OPA to return a "403 Forbidden" response code when an action is not allowed, you would need to implement this logic in your service that interfaces between Ory Oathkeeper and OPA. This service would need to interpret the decision from OPA and return the appropriate HTTP status code to Ory Oathkeeper. For more information on how to integrate OPA with Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/pipeline/authz#remote_json).

remote_json

example](https://www.ory.sh/docs/oathkeeper/pipeline/authz#remote_json-example)

To send a payload in the

remote_json

authorizer from Ory Oathkeeper, including information from headers, method, and path, you can use the

payload

configuration option. This option allows you to specify a JSON template that will be sent to the remote endpoint. Here's an example of how you can configure the

remote_json

authorizer to send such a payload:

json {   "authorizers": {     "remote_json": {       "enabled": true,       "config": {         "remote": "<http://my-remote-authorizer/authorize>",         "headers": {           "Content-Type": "application/json"         },         "payload": "{ \"subject\": \"{{ print .Subject }}\", \"method\": \"{{ print .Request.Method }}\", \"path\": \"{{ print .Request.URL.Path }}\", \"headers\": {{ marshal .Request.Header }} }"       }     }   } }

In this configuration: -

{{ print .Subject }}

will be replaced with the subject of the request. -

{{ print .Request.Method }}

will be replaced with the HTTP method of the request. -

{{ print .Request.URL.Path }}

will be replaced with the path of the request. -

{{ marshal .Request.Header }}

will include all headers of the request as a JSON object. The

payload

string is parsed using Go's

text/template

package and applied to an

AuthenticationSession

object. This allows you to include various pieces of information from the request in your payload. Remember that the

payload

field should be a string in the actual configuration file, even though it contains a JSON template. For more information on how to configure the

remote_json

authorizer, you can refer to the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/pipeline/authz#remote_json). [Source](https://www.ory.sh/docs/oathkeeper/pipeline/authz#remote_json)

The spaces between

print

and

.

in the template expressions (like

{{ print .Subject }}

) are not strictly necessary, but they are often included for better readability. Both

{{ print .Subject }}

and

{{ print.Subject }}

would work the same way in Go templates. However, it's generally considered good practice to include the space for clarity and consistency. This is because: 1. It makes the template more readable, especially when dealing with more complex expressions. 2. It follows the convention used in most Go template examples and documentation. 3. It helps to visually separate the function name (

print

) from the object property (

.Subject

). In the context of Ory Oathkeeper's configuration, you'll typically see the space included, as shown in the documentation examples:

json "payload": "{ \"subject\": \"{{ print .Subject }}\", \"method\": \"{{ print .Request.Method }}\" }"

[Source](https://www.ory.sh/docs/oathkeeper/pipeline/authz#remote_json) So, while both forms are technically correct, using

{{ print .Subject }}

is the more common and recommended approach in Ory Oathkeeper configurations and Go templates in general.

Certainly! Here's an example of how you can configure the

remote_json

authorizer in Ory Oathkeeper to send a payload that includes the HTTP method, path, and a role from the header:

json {   "authorizers": {     "remote_json": {       "enabled": true,       "config": {         "remote": "<http://my-remote-authorizer/authorize>",         "headers": {           "Content-Type": "application/json"         },         "payload": "{ \"method\": \"{{ print .Request.Method }}\", \"path\": \"{{ print .Request.URL.Path }}\", \"role\": \"{{ print .Request.Header.Get \\\"X-User-Role\\\" }}\" }"       }     }   } }

In this configuration: -

{{ print .Request.Method }}

will be replaced with the HTTP method of the request. -

{{ print .Request.URL.Path }}

will be replaced with the path of the request. -

{{ print .Request.Header.Get \"X-User-Role\" }}

will be replaced with the value of the "X-User-Role" header from the request. The resulting payload sent to the remote authorizer will look something like this:

json {   "method": "GET",   "path": "/api/resource",   "role": "admin" }

Note that we're assuming the role is sent in a header named "X-User-Role". If your role information is in a different header, you should replace "X-User-Role" with the appropriate header name. Remember that the

payload

field should be a string in the actual configuration file, even though it contains a JSON template. The double backslashes before the quotes in

\\\"X-User-Role\\\"

are necessary to properly escape the quotes within the JSON string. For more information on how to configure the

remote_json

authorizer, you can refer to the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/pipeline/authz#remote_json).

If you're passing your role information in a header named "role" instead of "X-User-Role", you can easily adjust the payload configuration in the

remote_json

authorizer. Here's how you can modify the payload to use the "role" header:

json {   "authorizers": {     "remote_json": {       "enabled": true,       "config": {         "remote": "<http://my-remote-authorizer/authorize>",         "headers": {           "Content-Type": "application/json"         },         "payload": "{ \"method\": \"{{ print .Request.Method }}\", \"path\": \"{{ print .Request.URL.Path }}\", \"role\": \"{{ print .Request.Header.Get \\\"role\\\" }}\" }"       }     }   } }

In this configuration, we've changed

{{ print .Request.Header.Get \"X-User-Role\" }}

to

{{ print .Request.Header.Get \"role\" }}

. This will retrieve the value from the "role" header instead of "X-User-Role". The resulting payload sent to the remote authorizer will look something like this:

json {   "method": "GET",   "path": "/api/resource",   "role": "admin" }

Remember that header names in HTTP are case-insensitive, so "role", "Role", or "ROLE" will all match the same header. For more information on how to configure the

remote_json

authorizer and use request data in the payload, you can refer to the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/pipeline/authz#remote_json).

The error you're encountering suggests that the

Request

field is not directly accessible in the

AuthenticationSession

struct that Ory Oathkeeper is using in this context. This is likely due to a change in the structure or naming of the fields available in the template. To resolve this issue, you should use the

MatchContext

field instead of

Request

. Here's the corrected payload configuration:

json "payload": "{\"method\": \"{{ print .MatchContext.Method }}\", \"path\": \"{{ print .MatchContext.URL.Path }}\"}"

This change is based on the

AuthenticationSession

struct definition provided in the Ory Oathkeeper documentation:

go type AuthenticationSession struct {     Subject      string     Extra        map[string]interface{}     Header       http.Header     MatchContext MatchContext   }      type MatchContext struct {     RegexpCaptureGroups []string     URL                 *url.URL     Method              string     Header              http.Header   }

[Source](https://www.ory.sh/docs/oathkeeper/pipeline#session) In this structure, the HTTP method and URL path are accessible through the

MatchContext

field. If you also need to include a header value (like the role we discussed earlier), you can do so like this:

json "payload": "{\"method\": \"{{ print .MatchContext.Method }}\", \"path\": \"{{ print .MatchContext.URL.Path }}\", \"role\": \"{{ print .MatchContext.Header.Get \\\"role\\\" }}\"}"

This configuration should work correctly with the current structure of the

AuthenticationSession

in Ory Oathkeeper.

@chilly-king-10285 getting error=map[messagenet/http HTTP/1.x transport connection broken: malformed HTTP response. from oathkeeper

A message from kapa.ai

This error message suggests that Ory Oathkeeper is receiving a malformed HTTP response from the remote service it's trying to communicate with. This could be happening in the context of the

remote_json

authorizer when it's making a request to the remote authorization service (like your OPA instance). Here are a few potential reasons and solutions for this issue: 1. Incorrect remote service URL: Double-check the URL specified in the

remote

field of your

remote_json

authorizer configuration. Make sure it's correct and the service is accessible from Oathkeeper. 2. Misconfigured remote service: The service Oathkeeper is trying to reach (e.g., your OPA instance) might be misconfigured and sending invalid HTTP responses. Check the logs of your remote service for any errors. 3. Network issues: There might be network connectivity problems between Oathkeeper and the remote service. Ensure that the network policies allow this communication. 4. Incompatible response format: The remote service might be sending a response in a format that Oathkeeper doesn't expect. Ensure that your remote service is sending valid HTTP responses with the correct status codes (200 for allow, 403 for deny). 5. Timeout issues: If the remote service is taking too long to respond, it might result in a partial response that Oathkeeper interprets as malformed. You might need to adjust timeout settings. To troubleshoot this: 1. Check Oathkeeper's logs for more detailed error messages. 2. Verify the configuration of your

remote_json

authorizer, especially the

remote

URL. 3. Test the remote service independently to ensure it's functioning correctly and returning valid HTTP responses. 4. Check network connectivity between Oathkeeper and the remote service. If you're still having issues after checking these points, you might want to reach out to the Ory community or support for more specific assistance, as the exact cause might depend on your particular setup and configuration. [Source: Ory Oathkeeper documentation on

remote_json

authorizer](https://www.ory.sh/docs/oathkeeper/pipeline/authz#remote_json)

The error message you're seeing suggests that Ory Oathkeeper is receiving a malformed HTTP response from a remote service it's trying to communicate with. This could be happening during the authentication or authorization process, possibly when Oathkeeper is trying to communicate with your Open Policy Agent (OPA) service or another remote service configured in your setup. Here are a few things you can check to troubleshoot this issue: 1. Remote Service Configuration: Ensure that the URL and port of the remote service (like OPA) are correctly configured in your Oathkeeper settings. Double-check the

remote

field in your

remote_json

authorizer configuration. 2. Network Connectivity: Verify that Oathkeeper can reach the remote service. If you're running in Kubernetes, make sure the service names and network policies are correctly set up. 3. Remote Service Response: Check the logs of your remote service (e.g., OPA) to see if it's receiving the requests from Oathkeeper and if it's responding correctly. The remote service should be returning valid HTTP responses. 4. SSL/TLS Configuration: If you're using HTTPS, ensure that SSL/TLS is correctly configured on both Oathkeeper and the remote service. 5. Payload Format: Verify that the payload you're sending from Oathkeeper (as we discussed in previous messages) is correctly formatted and can be processed by your remote service. 6. Response Headers: Ensure that the remote service is setting the correct Content-Type header in its responses. For JSON responses, it should be

application/json

. 7. Oathkeeper Logs: Check the Oathkeeper logs for more detailed error messages that might provide additional context about where and why the error is occurring. If you're still having trouble after checking these points, you might need to use a network debugging tool like

tcpdump

or Wireshark to capture and analyze the network traffic between Oathkeeper and the remote service to identify where exactly the malformed response is coming from. For more information on troubleshooting Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/). If the issue persists, you might want to reach out to the Ory community or support for more specific assistance.

Ory Oathkeeper provides support for gRPC middleware, allowing you to directly embed it into your Go application as a gRPC interceptor. This feature enables you to handle gRPC traffic using Oathkeeper without the need for an additional network hop. Here's an overview of how the gRPC middleware logic works in Ory Oathkeeper: 1. The gRPC middleware is implemented as both a unary and stream interceptor. 2. You can set up the gRPC middleware in your Go application like this:

go import (    "<http://github.com/ory/oathkeeper/middleware|github.com/ory/oathkeeper/middleware>"    "<http://google.golang.org/grpc|google.golang.org/grpc>"   )      func setup() {    oathkeeperMW, err := middleware.New(ctx, middleware.WithConfigFile("path/to/config"))    if err != nil {     return nil, nil, fmt.Errorf("failed to create oathkeeper middleware: %w", err)    }        s := grpc.NewServer(     grpc.UnaryInterceptor(mw.UnaryInterceptor()),     grpc.StreamInterceptor(mw.StreamInterceptor()),    )        // register your service to s, start the server, ...   }

3. The middleware will match only against explicit gRPC matchers, which you can use by specifying

authority

and

full_method

in your JSON configuration:

json {     "id": "some-id",   "version": "v0.36.0-beta.4",   "match": {       "authority": "<http://example.com|example.com>",     "full_method": "my.grpc.package/MyService/MyMethod"     },   "authenticators": [{ "handler": "noop" }],     "authorizer": { "handler": "allow" },     "mutators": [{ "handler": "noop" }],     "errors": [{ "handler": "json" }]   }

4. The gRPC traffic will then be handled by the middleware as if it were a standalone Ory Oathkeeper instance, just without the added network hop. It's important to note that this feature is experimental and may change. Ory cannot give any compatibility guarantees regarding the API. Also, this option is only available if you are using Go and gRPC. [Source](https://www.ory.sh/docs/oathkeeper/grpc-middleware)

The error you're encountering is likely due to an incorrect configuration in the

mutators

section of your Ory Oathkeeper rule. Let's break down the issue and provide a corrected version: 1. The

X-Forwarded-For

header value should not be a URL. This header is typically used to identify the originating IP address of a client connecting through an HTTP proxy or load balancer. 2. The angle brackets (

<

and

>

) around the URL are unnecessary and may be causing parsing issues. Here's a corrected version of your mutator configuration:

json "mutators": [   {     "handler": "header",     "config": {       "headers": {         "X-Validated-By": "Oathkeeper",         "X-Forwarded-For": "{{ print .Request.RemoteAddr }}"       }     }   } ]

In this corrected version: 1. We've kept the

X-Validated-By

header as is. 2. We've replaced the URL in the

X-Forwarded-For

header with a template that will print the remote address of the request. This is more appropriate for the

X-Forwarded-For

header. If you actually intended to set a custom header with the gateway URL, you should use a different header name, like this:

json "mutators": [   {     "handler": "header",     "config": {       "headers": {         "X-Validated-By": "Oathkeeper",         "X-Gateway-URL": "<http://gateway-proxy.gloo-system.svc.cluster.local:8080>"       }     }   } ]

Remember, the

header

mutator in Ory Oathkeeper is used to add or modify HTTP headers in the request before it's forwarded to the upstream service. The keys in the

headers

object are the header names, and the values are strings that can include template expressions. For more information on how to configure mutators in Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation on mutators](https://www.ory.sh/docs/oathkeeper/pipeline/mutator).

The error message you're seeing indicates that there's a mismatch in the expected format for the

mutators

configuration in Ory Oathkeeper. The configuration you've provided is in YAML format, but it seems that Oathkeeper is expecting a JSON object for the

mutators

field. To resolve this issue, you need to adjust your configuration to match the expected format. Here's the correct JSON format for the

mutators

configuration:

json {   "mutators": [     {       "handler": "header",       "config": {         "headers": {           "X-Validated-By": "Oathkeeper"         }       }     }   ] }

If you prefer to use YAML format, make sure your YAML is properly indented and structured. Here's the correct YAML format:

yaml mutators:   - handler: header     config:       headers:         X-Validated-By: "Oathkeeper"

Make sure that this

mutators

configuration is part of a larger rule configuration in your Oathkeeper setup. Remember, when configuring Ory Oathkeeper, pay attention to the format (JSON or YAML) you're using and ensure it matches what Oathkeeper expects. The

mutators

field should be an array of objects, each representing a mutator configuration. For more information on configuring mutators in Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation on mutators](https://www.ory.sh/docs/oathkeeper/pipeline/mutator).

The configuration you've provided for the mutator looks correct in terms of structure and syntax. It's a valid YAML representation of a header mutator in Ory Oathkeeper. However, there might be a context-specific issue that's causing a problem. Let's break it down:

yaml mutators:   - handler: header     config:       headers:         X-User: "Oathkeeper"

This configuration sets up a header mutator that adds or modifies the

X-User

header with the value "Oathkeeper". If you're still encountering an error, it could be due to one of the following reasons: 1. Format mismatch: Ensure that your entire configuration file is consistently using YAML format. Mixing JSON and YAML can cause parsing errors. 2. Indentation: YAML is sensitive to indentation. Make sure your indentation is consistent throughout the file. 3. Context: This mutator configuration should be part of a larger rule configuration. Ensure it's placed correctly within your Oathkeeper rules. 4. Static value: The current configuration sets a static value "Oathkeeper" for the X-User header. If you intended to use a dynamic value (like the authenticated user's ID), you should use a template expression instead. For example:

yaml    mutators:      - handler: header        config:          headers:            X-User: "{{ print .Subject }}"

This would set the X-User header to the subject of the authenticated request. 5. Multiple mutators: If you have multiple mutators, ensure they're all listed under the

mutators

key with proper indentation. If you're still encountering issues after checking these points, it would be helpful to see the complete rule configuration and the exact error message you're receiving. For more information on configuring mutators in Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation on mutators](https://www.ory.sh/docs/oathkeeper/pipeline/mutator#header).

Ory Oathkeeper supports gRPC through its gRPC middleware feature. This allows you to embed Oathkeeper directly into your Go application as a gRPC interceptor, enabling you to handle gRPC traffic without the need for an additional network hop. Here's how Oathkeeper supports gRPC: 1. gRPC Middleware: Oathkeeper provides both unary and stream interceptors for gRPC. This means it can handle both unary RPC calls and streaming RPC calls. 2. Integration in Go Applications: You can set up the gRPC middleware in your Go application using the following code:

go import (    "<http://github.com/ory/oathkeeper/middleware|github.com/ory/oathkeeper/middleware>"    "<http://google.golang.org/grpc|google.golang.org/grpc>"   )      func setup() {    oathkeeperMW, err := middleware.New(ctx, middleware.WithConfigFile("path/to/config"))    if err != nil {     return nil, nil, fmt.Errorf("failed to create oathkeeper middleware: %w", err)    }        s := grpc.NewServer(     grpc.UnaryInterceptor(mw.UnaryInterceptor()),     grpc.StreamInterceptor(mw.StreamInterceptor()),    )        // register your service to s, start the server, ...   }

3. gRPC-specific Matchers: Oathkeeper uses explicit gRPC matchers in its configuration. You can specify

authority

and

full_method

in your JSON configuration to match gRPC requests:

json {     "id": "some-id",   "version": "v0.36.0-beta.4",   "match": {       "authority": "<http://example.com|example.com>",     "full_method": "my.grpc.package/MyService/MyMethod"     },   "authenticators": [{ "handler": "noop" }],     "authorizer": { "handler": "allow" },     "mutators": [{ "handler": "noop" }],     "errors": [{ "handler": "json" }]   }

4. Handling gRPC Traffic: Once set up, the gRPC traffic will be handled by the middleware as if it were a standalone Oathkeeper instance, but without the additional network hop. It's important to note that this gRPC middleware feature is experimental and may be subject to changes. Ory does not provide compatibility guarantees for this API. Also, this feature is only available when using Go and gRPC. [Source: https://www.ory.sh/docs/oathkeeper/grpc-middleware]

While the gRPC middleware is the primary way Ory Oathkeeper supports gRPC, there are a few other approaches you could consider for integrating authentication and authorization with gRPC services: 1. Reverse Proxy: You could use Ory Oathkeeper as a reverse proxy in front of your gRPC services. This would require translating between HTTP/2 and gRPC, which Oathkeeper doesn't do natively. You might need to use an additional tool like Envoy for this purpose. 2. External Authorization: Some gRPC-compatible API gateways support external authorization. For example, you could use Envoy with its External Authorization filter, configuring it to call Oathkeeper's decision API for each request. 3. Custom Integration: You could implement your own gRPC interceptors that call Oathkeeper's decision API for each request. This would allow you to use Oathkeeper's authentication and authorization logic without embedding it directly in your application. 4. Sidecar Pattern: Deploy Oathkeeper as a sidecar container alongside your gRPC services in a Kubernetes environment. The sidecar could handle authentication and authorization before passing requests to the main service container. 5. Service Mesh: If you're using a service mesh like Istio, you might be able to configure it to handle authentication and authorization using policies, potentially integrating with Oathkeeper's decision API. However, it's important to note that these alternatives are not officially supported or documented by Ory for use with Oathkeeper and gRPC. They would require additional configuration and potentially custom development. For the most up-to-date and officially supported method, the gRPC middleware feature remains the recommended approach for integrating Ory Oathkeeper with gRPC services. If you need more specific solutions, you might want to consider reaching out to the Ory community or consulting the latest documentation for any updates or new features related to gRPC support.

Yes, Ory Oathkeeper does have a feature called

strip_path

. This feature is part of the

upstream

configuration in an Oathkeeper rule. The

strip_path

field, if set, replaces the provided path prefix when forwarding the requested URL to the upstream URL. This can be useful when you want to remove a certain path prefix from the request URL before it's forwarded to the upstream service. Here's an example of how it can be used in a rule:

json {   "id": "some-id",   "upstream": {     "url": "<http://my-backend-service>",     "strip_path": "/api/v1"   },   "match": {     "url": "<http://my-app/some-route/<.*>>",     "methods": ["GET", "POST"]   },   "authenticators": [{ "handler": "noop" }],   "authorizer": { "handler": "allow" },   "mutators": [{ "handler": "noop" }],   "errors": [{ "handler": "json" }] }

In this example, if a request comes in for

<http://my-app/some-route/api/v1/users>

, Oathkeeper will forward the request to

<http://my-backend-service/users>

(stripping out the

/api/v1

prefix). For more information, you can refer to the [Ory Oathkeeper documentation on API access rules](https://www.ory.sh/docs/oathkeeper/api-access-rules#examples).

Your configuration for a custom authenticator using the "remote" handler in Ory Oathkeeper is close, but there are a few adjustments needed to make it correct. Here's the corrected version with explanations:

json {   "handler": "remote",   "config": {     "remote": "<http://auth-service.default.svc.cluster.local:8085/user/>{{.MatchContext.Header.Get \"Role\"}}/sites",     "forward_response_headers_to_upstream": ["Authorization"]   } }

Let's break down the changes: 1. The

url

field should be

remote

. This is the correct key for specifying the remote authenticator's URL in the "remote" handler configuration. 2. Remove the angle brackets (

<

and

>

) around the URL. These are not needed and can cause parsing issues. 3. The template syntax for accessing headers has been corrected. Use

.MatchContext.Header.Get "Role"

instead of

.MatchContext.RequestHeaders.Role

. 4. The

forward_headers

field should be

forward_response_headers_to_upstream

. This specifies which headers from the remote authenticator's response should be forwarded to the upstream service. This configuration will send a request to your custom authentication service, including the "Role" header from the original request in the URL. The "Authorization" header from the authenticator's response will be forwarded to the upstream service if the authentication is successful. Remember that the remote authenticator should return either a "200 OK" status code to allow access or a "401 Unauthorized" status code to deny access. For more information on configuring custom authenticators in Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation on authenticators](https://www.ory.sh/docs/oathkeeper/pipeline/authn#remote).

The error message "additionalProperties 'remote' not allowed" suggests that there's an issue with the configuration structure in your Ory Oathkeeper setup, specifically related to the

remote

authenticator. This error typically occurs when you're trying to use a property that isn't recognized in the current context. In the case of the

remote

authenticator, the correct configuration structure is slightly different from what you might have used. Here's the correct way to configure the

remote

authenticator:

json {   "authenticators": [     {       "handler": "remote",       "config": {         "remote": "<http://my-authentication-service/endpoint>",         "forward_response_headers_to_upstream": ["X-User-ID", "X-User-Name"]       }     }   ] }

Key points to note: 1. The

remote

field should be inside the

config

object, not at the same level as

handler

. 2. Make sure you're placing this configuration in the correct place within your Oathkeeper rules. If you're still encountering issues, double-check your entire configuration file for any misplaced properties or incorrect nesting. For more detailed information on configuring the

remote

authenticator, you can refer to the [Ory Oathkeeper documentation on authenticators](https://www.ory.sh/docs/oathkeeper/pipeline/authn#remote). If the problem persists, you might want to share your full configuration (with sensitive information redacted) to get more specific guidance.

Thank you for providing your Ory Oathkeeper configuration. I can see a few issues that need to be addressed. Let me help you correct them: 1. For the

oauth2_introspection

authenticator: - The

introspection_url

should not be enclosed in angle brackets (

<

and

>

). 2. For the

remote

authenticator: - The

url

field should be

remote

instead. - The URL should not be enclosed in angle brackets. - The template syntax for accessing headers is incorrect. Here's the corrected configuration:

yaml authenticators:   oauth2_introspection:     enabled: true     config:       introspection_url: "<http://hydra:4445/admin/oauth2/introspect>"    remote:     enabled: true     config:       remote: "<http://auth-service.default.svc.cluster.local:8085/user/{{.MatchContext.Header.Get> \"Role\"}}/sites"

Key changes: - Removed angle brackets from URLs. - Changed

url

to

remote

in the

remote

authenticator config. - Corrected the template syntax for accessing the

Role

header. These changes should resolve the configuration issues. Remember to adjust the URLs if they need to be different in your specific setup. For more information on configuring authenticators in Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation on authenticators](https://www.ory.sh/docs/oathkeeper/pipeline/authn).

The error message you're seeing indicates that there's an issue with the

remote

authenticator configuration in your Ory Oathkeeper setup. Specifically, the "remote" property is not allowed in the current context. Let's address this issue and correct your configuration. Here's how you can fix the

remote

authenticator configuration: 1. Remove the angle brackets (

<

and

>

) around the URLs. These are not needed and can cause parsing issues. 2. Correct the template syntax for accessing headers in the

remote

authenticator. Here's the corrected configuration for the

remote

and

oauth2_introspection

authenticators:

yaml authenticators:   oauth2_introspection:     enabled: true     config:       introspection_url: "<http://hydra:4445/admin/oauth2/introspect>"       cache:         enabled: false         max_cost: 1000       retry:         give_up_after: 1s         max_delay: 100ms       scope_strategy: none       pre_authorization:         enabled: false    remote:     enabled: true     config:       remote: "<http://auth-service.default.svc.cluster.local:8085/user/{{.MatchContext.Header.Get> \"Role\"}}/sites"

Key changes: - Removed angle brackets from URLs. - Corrected the template syntax for accessing the

Role

header in the

remote

authenticator. - Ensured that the

remote

field is used instead of

url

in the

remote

authenticator config. These changes should resolve the configuration issues you're experiencing. Remember to adjust the URLs if they need to be different in your specific setup. For more information on configuring authenticators in Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation on authenticators](https://www.ory.sh/docs/oathkeeper/pipeline/authn). If you continue to experience issues after making these changes, please provide the full, updated configuration (with sensitive information redacted) for further assistance.

Yes, that's correct. In Ory Oathkeeper, if you define multiple authenticators for an access rule, they are evaluated in order, and the first authenticator that successfully validates the credentials will be used. The subsequent authenticators will be ignored. This behavior is explicitly described in the Ory Oathkeeper documentation: "You can define more than one authenticator in the Access Rule. The first authenticator that's able to handle the credentials will be consulted and other authenticators will be ignored." [Source: Ory Oathkeeper Documentation](https://www.ory.sh/docs/oathkeeper/pipeline/authn) For example, if you have a configuration like this:

json {     "authenticators": [       {         "handler": "a"       },       {         "handler": "b"       },       {         "handler": "c"       }     ]   }

If handler

a

is able to validate the credentials, then handlers

b

and

c

will be ignored. If

a

can't handle the credentials but

b

can, then

a

and

c

will be ignored. It's important to note that "handling" the credentials means that the authenticator knows how to process them, not necessarily that the credentials are valid. If a handler encounters invalid credentials, the subsequent handlers will still be ignored. This design allows you to set up a fallback system of authentication methods, where you can try different authentication strategies in a specific order.

Yes, you can call an API and add its response to the request in Ory Oathkeeper. This can be achieved using the

hydrator

mutator. The

hydrator

mutator allows you to fetch additional data from external APIs and use it to modify the request before it's forwarded to the upstream service. Here's how you can configure the

hydrator

mutator to call an API and add its response to the request:

json {   "mutators": [     {       "handler": "hydrator",       "config": {         "api": {           "url": "<http://my-backend-api>"         }       }     }   ] }

The

hydrator

mutator works as follows: 1. It makes an upstream HTTP POST call to the API specified in the

api.url

configuration. 2. The request to the API contains a JSON representation of the

AuthenticationSession

struct in the body. 3. The API is expected to return a similar JSON object, but with

extra

or

header

fields modified. 4. The

AuthenticationSession

from this response replaces the original one and is passed to the next mutator or to the upstream service. You can use the response from the API to set custom headers or add data to the

extra

field, which can be used by subsequent mutators or forwarded to the upstream service. For example, if you want to add a custom header based on the API response:

json {   "mutators": [     {       "handler": "hydrator",       "config": {         "api": {           "url": "<http://my-backend-api>"         }       }     },     {       "handler": "header",       "config": {         "headers": {           "X-Custom-Data": "{{ print .Extra.custom_data }}"         }       }     }   ] }

This configuration first calls the API using the

hydrator

mutator, then uses the

header

mutator to add a custom header based on the data returned by the API. Remember that the

hydrator

mutator supports caching to improve performance for repeated requests. [Source: Ory Oathkeeper Documentation on Mutators](https://www.ory.sh/docs/oathkeeper/pipeline/mutator#hydrator)

Based on the response you've provided, it seems you're getting a JSON object from an API call. This could be the result of using the

hydrator

mutator in Ory Oathkeeper, which we discussed earlier. Let's see how you can use this response in your Oathkeeper configuration. You can use the

hydrator

mutator to fetch this data and then use other mutators to add this information to your request. Here's an example of how you might configure this: 1. First, use the

hydrator

mutator to fetch the data:

json {   "mutators": [     {       "handler": "hydrator",       "config": {         "api": {           "url": "<http://your-api-endpoint>"         }       }     }   ] }

2. Then, you can use the

header

mutator to add this information as headers to your request:

json {   "mutators": [     {       "handler": "hydrator",       "config": {         "api": {           "url": "<http://your-api-endpoint>"         }       }     },     {       "handler": "header",       "config": {         "headers": {           "X-User-ID": "{{ print .Extra.user_id }}",           "X-User-Type": "{{ print .Extra.type }}",           "X-Allowed-Site-IDs": "{{ print .Extra.allowed_site_ids }}"         }       }     }   ] }

This configuration will: 1. Call your API using the

hydrator

mutator. 2. Take the response from the API and add it to the

.Extra

field of the authentication session. 3. Use the

header

mutator to add the information from the API response as headers to the request. Remember that the exact field names (

.Extra.user_id

,

.Extra.type

, etc.) might vary depending on how the

hydrator

mutator processes the API response. You may need to adjust these based on the actual structure of the

.Extra

field after hydration. For more information on how to use mutators in Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation on mutators](https://www.ory.sh/docs/oathkeeper/pipeline/mutator).

The error message you're seeing indicates that the

hydrator

mutator is disabled in your Ory Oathkeeper configuration. This means that any rules using this mutator will not work properly. To resolve this issue, you need to enable the

hydrator

mutator in your Oathkeeper configuration. Here's how you can fix this: 1. Locate your Ory Oathkeeper configuration file (usually named

oathkeeper.yml

or similar). 2. Find the

mutators

section in the configuration. 3. Add or modify the

hydrator

configuration to enable it. Here's an example of how it should look:

yaml mutators:   hydrator:     enabled: true     config:       api:         url: "<http://your-api-endpoint>"

4. Make sure the

url

in the

api

section points to the correct endpoint for your hydrator API. 5. Save the configuration file and restart Ory Oathkeeper to apply the changes. After making these changes, the

hydrator

mutator should be enabled and your rules using it should work properly. For more information on configuring mutators in Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation on mutators](https://www.ory.sh/docs/oathkeeper/pipeline/mutator#hydrator). If you continue to experience issues after making these changes, you may want to review your entire Oathkeeper configuration to ensure all components are properly configured and enabled.

Based on your response and the requirement to pass

allowed_site_ids

as a header, we can use the

hydrator

mutator in combination with the

header

mutator in Ory Oathkeeper to achieve this. Here's how you can configure it: 1. First, use the

hydrator

mutator to fetch the data:

json {   "mutators": [     {       "handler": "hydrator",       "config": {         "api": {           "url": "<http://your-api-endpoint>"         }       }     }   ] }

2. Then, use the

header

mutator to add the

allowed_site_ids

as a header:

json {   "mutators": [     {       "handler": "hydrator",       "config": {         "api": {           "url": "<http://your-api-endpoint>"         }       }     },     {       "handler": "header",       "config": {         "headers": {           "X-Allowed-Site-IDs": "{{ print .Extra.allowed_site_ids }}"         }       }     }   ] }

This configuration will: 1. Call your API using the

hydrator

mutator. 2. Take the response from the API and add it to the

.Extra

field of the authentication session. 3. Use the

header

mutator to add the

allowed_site_ids

from the API response as a header to the request. Note that since

allowed_site_ids

is an empty array in your example, the header value will be empty. If you want to handle this case differently, you might need to add some logic in your API or use a more complex template in the header configuration. For example, if you want to set the header only if

allowed_site_ids

is not empty, you could use:

json "X-Allowed-Site-IDs": "{{ if .Extra.allowed_site_ids }}{{ join \",\" .Extra.allowed_site_ids }}{{ end }}"

This will join the array elements with commas if

allowed_site_ids

is not empty, and set no header if it is empty. Remember to ensure that the

hydrator

mutator is enabled in your Oathkeeper configuration as discussed in our previous interaction. For more information on configuring mutators in Ory Oathkeeper, you can refer to the [Ory Oathkeeper documentation on mutators](https://www.ory.sh/docs/oathkeeper/pipeline/mutator).

Based on the error message you're seeing, it appears that the

hydrator

mutator in Ory Oathkeeper is failing to get a successful response from the external API it's calling. Unfortunately, Ory Oathkeeper's default logging doesn't provide extensive details about mutator operations. However, there are a few things you can do to get more information and troubleshoot this issue: 1. Increase Log Level: You can increase Oathkeeper's log level to get more detailed logs. Set the

LOG_LEVEL

environment variable to

debug

or even

trace

. For example:

export LOG_LEVEL=debug

[Source: Ory Oathkeeper Documentation on Logging](https://www.ory.sh/docs/oathkeeper/reference/configuration) 2. Enable Sensitive Value Logging: If you want to see sensitive values in the logs (which might include details about the API call), you can set:

export LOG_LEAK_SENSITIVE_VALUES=true

Be cautious with this in production environments as it may log sensitive information. 3. Check API Endpoint: Ensure that the API endpoint configured in the

hydrator

mutator is correct and accessible from where Oathkeeper is running. 4. Examine Network Logs: If possible, examine the network logs or use a tool like tcpdump to capture the network traffic between Oathkeeper and the external API. This can give you more details about the request and response. 5. Implement Custom Logging: If you have control over the external API that the

hydrator

is calling, you could implement more detailed logging on that side to see what request it's receiving and what response it's sending. 6. Use Distributed Tracing: If your setup supports it, implementing distributed tracing can provide more insights into the request flow, including the calls made by mutators. Remember, the

hydrator

mutator expects a 200 OK response from the API it calls. Any other response code will be treated as an error. Make sure your API is returning the correct status code. If you continue to have issues after trying these steps, you might want to reach out to the Ory community or support channels for more specific assistance, as they might have additional insights or newer features for debugging mutator issues.

Thank you for providing your Ory Oathkeeper configuration. I can see a few issues that need to be addressed in both your global configuration and the rule configuration. Let me help you correct them: 1. In the global configuration: - Remove the angle brackets (

<

and

>

) around the URL in the

hydrator

config. - The

X-Authented

header has a typo. It should probably be

X-Authenticated

. 2. In the rule configuration: - Again, remove the angle brackets around the URL in the

hydrator

config. - The

X-Authented

header has the same typo. Here's the corrected global configuration:

yaml mutators:   hydrator:     enabled: true     config:       api:         url: "<http://auth-service.default.svc.cluster.local:8085/user/653acd38f1e2e4b3a2d4e124/sites>"   header:     enabled: true     config:       headers:         X-Authenticated: "true"         X-Allowed-Site-IDs: "{{ print .Extra.allowed_site_ids }}"

And here's the corrected rule configuration:

json "mutators": [   {     "handler": "hydrator",     "config": {       "api": {         "url": "<http://auth-service.default.svc.cluster.local:8085/user/653acd38f1e2e4b3a2d4e124/sites>"       }     }   },   {     "handler": "header",     "config": {       "headers": {         "X-Authenticated": "true",         "X-Allowed-Site-IDs": "{{ print .Extra.allowed_site_ids }}"       }     }   } ]

These changes should resolve the configuration issues. Remember that the

hydrator

mutator will make a request to the specified URL and add the response to the

.Extra

field of the authentication session. The

header

mutator will then use this data to set the headers. If you're still encountering issues after making these changes, it could be due to the response from your auth service. Make sure it's returning a 200 OK status and that the response includes an

allowed_site_ids

field. [Source: Ory Oathkeeper documentation on mutators](https://www.ory.sh/docs/oathkeeper/pipeline/mutator)

To specify whether to make a GET or POST call from the

hydrator

mutator in Ory Oathkeeper, you can use the

method

configuration option. By default, the

hydrator

mutator uses a POST request, but you can explicitly set it to GET if needed. Here's how you can configure the

hydrator

mutator to make a GET request:

json {   "mutators": [     {       "handler": "hydrator",       "config": {         "api": {           "url": "<http://your-api-endpoint>",           "method": "GET"         }       }     }   ] }

For a POST request (which is the default), you can either omit the

method

field or explicitly set it to POST:

json {   "mutators": [     {       "handler": "hydrator",       "config": {         "api": {           "url": "<http://your-api-endpoint>",           "method": "POST"         }       }     }   ] }

Remember that when using POST, the

hydrator

mutator sends a JSON representation of the

AuthenticationSession

struct in the request body. If you're using GET, no body is sent with the request. If you need to send specific data with your GET request, you can include it in the URL as query parameters. For more information on configuring the

hydrator

mutator, you can refer to the [Ory Oathkeeper documentation on mutators](https://www.ory.sh/docs/oathkeeper/pipeline/mutator#hydrator).

I apologize for the confusion in my previous response. It appears that the

method

property is not supported in the

hydrator

mutator configuration for Ory Oathkeeper, contrary to what I suggested earlier. Let's correct this information and address the error you're seeing. The error message indicates that the

method

property is not allowed in the configuration for the

hydrator

mutator. This means that Ory Oathkeeper does not support explicitly specifying the HTTP method for the

hydrator

mutator. To resolve this issue, you should remove the

method

property from your

hydrator

mutator configuration. The

hydrator

mutator in Ory Oathkeeper uses POST requests by default, and this behavior cannot be changed through configuration. Here's how your corrected

hydrator

mutator configuration should look:

json {   "mutators": [     {       "handler": "hydrator",       "config": {         "api": {           "url": "<http://your-api-endpoint>"         }       }     }   ] }

Key points to remember: 1. The

hydrator

mutator always uses POST requests to call the external API. 2. You cannot specify or change the HTTP method used by the

hydrator

mutator. 3. The

hydrator

mutator sends a JSON representation of the

AuthenticationSession

struct in the request body. If you need to make GET requests or use other HTTP methods, you might need to implement a custom solution or use a different approach to achieve your desired functionality. For the most up-to-date and accurate information on configuring the

hydrator

mutator, please refer to the [official Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/pipeline/mutator#hydrator). I apologize for any confusion my previous response may have caused. Thank you for bringing this to my attention, as it allows me to provide more accurate information.

The error message "The call to an external API returned an invalid JSON object" suggests that the

hydrator

mutator in Ory Oathkeeper successfully made a call to the external API, but the response it received was not in a valid JSON format. This issue could be caused by several factors: 1. The external API is not returning a properly formatted JSON response. 2. There might be unexpected characters or formatting issues in the API response. 3. The API might be returning an error message in plain text instead of JSON. To resolve this issue, you can try the following steps: 1. Check the external API: - Verify that the API endpoint you're calling is correct. - Test the API independently to ensure it's returning valid JSON. - If possible, examine the raw response from the API to see what it's actually returning. 2. API Response Format: - Ensure that the API is returning a JSON object that matches the expected format for the

hydrator

mutator. - The response should typically include fields that can be mapped to the

AuthenticationSession

struct, particularly the

extra

or

header

fields. 3. Error Handling in the API: - Make sure the API handles errors by returning them in a valid JSON format rather than plain text. 4. Debugging: - If possible, increase the log level of Ory Oathkeeper to get more detailed error messages. You can do this by setting the

LOG_LEVEL

environment variable to

debug

. - You might also want to enable sensitive value logging temporarily to see the actual API response. Set

LOG_LEAK_SENSITIVE_VALUES=true

, but be cautious with this in production environments. 5. API Authentication: - If the API requires authentication, ensure that the correct credentials are being sent with the request. Remember, the

hydrator

mutator expects a specific response format from the API. If you have control over the API, make sure it's returning data in the correct structure expected by Oathkeeper. For more information on configuring and troubleshooting the

hydrator

mutator, you can refer to the [Ory Oathkeeper documentation on mutators](https://www.ory.sh/docs/oathkeeper/pipeline/mutator#hydrator). If you continue to face issues after trying these steps, you might need to examine the API response in detail or reach out to the Ory community or support channels for more specific assistance.

The response you've provided is a valid JSON object, which is good. This means that the external API you're calling from the

hydrator

mutator in Ory Oathkeeper is returning a properly formatted JSON response. Given this response, you can use it in your Oathkeeper configuration to add custom headers or modify the request. Here's how you can use this data with the

hydrator

and

header

mutators: 1. First, use the

hydrator

mutator to fetch this data:

json {   "handler": "hydrator",   "config": {     "api": {       "url": "<http://your-api-endpoint>"     }   } }

2. Then, use the

header

mutator to add this information as headers to your request:

json {   "handler": "header",   "config": {     "headers": {       "X-User-ID": "{{ print .Extra.user_id }}",       "X-User-Type": "{{ print .Extra.type }}",       "X-Allowed-Site-IDs": "{{ if .Extra.allowed_site_ids }}{{ join \",\" .Extra.allowed_site_ids }}{{ else }}empty{{ end }}"     }   } }

This configuration will: 1. Call your API using the

hydrator

mutator. 2. Take the response from the API and add it to the

.Extra

field of the authentication session. 3. Use the

header

mutator to add the information from the API response as headers to the request. Note that for the

X-Allowed-Site-IDs

header, we've added a condition to handle the case where

allowed_site_ids

is an empty array. If it's empty, the header will be set to "empty". You can adjust this as needed. Remember to ensure that both the

hydrator

and

header

mutators are enabled in your Oathkeeper configuration. [Source: Ory Oathkeeper documentation on mutators](https://www.ory.sh/docs/oathkeeper/pipeline/mutator)

Yes, you're correct. The

hydrator

mutator in Ory Oathkeeper expects the response from the external API to be in a specific format that matches the

AuthenticationSession

struct. The format you've mentioned is indeed the expected structure. Based on the Ory Oathkeeper documentation, the expected response format for the

hydrator

mutator should be:

json {     "subject": String,     "extra": Object,     "header": Object,     "match_context": {       "regexp_capture_groups": Object,       "url": Object     }   }

[Source](https://www.ory.sh/docs/oathkeeper/pipeline/mutator#hydrator) Given that your current API response is:

json {     "user_id": "653acd38f1e2e4b3a2d4e123",     "type": "admin",     "allowed_site_ids": [] }

You'll need to modify your API to return the response in the expected format. Here's an example of how you might structure the response:

json {   "subject": "653acd38f1e2e4b3a2d4e123",   "extra": {     "user_id": "653acd38f1e2e4b3a2d4e123",     "type": "admin",     "allowed_site_ids": []   },   "header": {},   "match_context": {     "regexp_capture_groups": {},     "url": {}   } }

In this example: - The

subject

is set to the

user_id

. - The original response is placed in the

extra

object. - The

header

and

match_context

objects are left empty, but you can populate them if needed. By adjusting your API to return this format, the

hydrator

mutator should be able to process the response correctly and make the data available for subsequent mutators or for forwarding to the upstream service. Remember, the

hydrator

mutator will replace the original

AuthenticationSession

with the one from this response, so make sure to include all necessary information in the response.

The error message you're seeing suggests that there's a mismatch between the JSON data structure and the Go struct that Ory Oathkeeper is using to unmarshal the response. Specifically, the issue seems to be with the

regexp_capture_groups

field in the

match_context

object. Based on the Ory Oathkeeper documentation, the

regexp_capture_groups

field should be an array of strings, not an object. Let's modify your API response to match the expected format:

json {     "subject": "653acd38f1e2e4b3a2d4e124",     "extra": {         "allowed_site_ids": [             "653acd38f1e2e4b3a2d4e201",             "653acd38f1e2e4b3a2d4e202"         ]     },     "header": {},     "match_context": {         "regexp_capture_groups": [],         "url": {}     } }

Key changes: 1. Changed

regexp_capture_groups

from an empty object

{}

to an empty array

[]

. If you need to include any capture groups, you would add them as string elements in this array. For example:

json "regexp_capture_groups": ["capture1", "capture2"]

Also, the

url

field in

match_context

should typically be a string representing the URL, not an empty object. If you don't have a specific URL to include, you can leave it as an empty string:

json "match_context": {     "regexp_capture_groups": [],     "url": "" }

Make these adjustments in your API response, and it should resolve the unmarshal error you're encountering. Remember, the structure of the response should match the

AuthenticationSession

struct in Ory Oathkeeper, as described in the [Ory Oathkeeper documentation](https://www.ory.sh/docs/oathkeeper/pipeline/mutator#hydrator). If you continue to face issues after making these changes, you might want to double-check the Oathkeeper version you're using and consult the specific documentation for that version, as the expected response format might vary slightly between versions.

The JSON response you've provided looks close to the correct format, but there's still a small issue with the

url

field in the

match_context

object. Let's make one more adjustment to resolve the error you're encountering. Here's the corrected version of your JSON response:

json {     "subject": "653acd38f1e2e4b3a2d4e124",     "extra": {         "allowed_site_ids": [             "653acd38f1e2e4b3a2d4e201",             "653acd38f1e2e4b3a2d4e202"         ]     },     "header": {},     "match_context": {         "regexp_capture_groups": [],         "url": ""     } }

The key change here is: - Changed the

url

field in

match_context

from an empty object

{}

to an empty string

""

. The

url

field in the

match_context

should be a string representing the URL. If you don't have a specific URL to include, you should use an empty string rather than an empty object. This change should resolve the unmarshal error you're experiencing. The structure now correctly matches the

AuthenticationSession

struct that Ory Oathkeeper uses to process the response from the

hydrator

mutator. If you're still encountering issues after making this change, here are a few additional things to check: 1. Ensure that your API is actually returning this exact JSON structure. 2. Verify that there are no extra characters or formatting issues in the API response. 3. Check the Ory Oathkeeper version you're using, as the expected format might vary slightly between versions. 4. Review your Oathkeeper configuration to ensure the

hydrator

mutator is correctly set up. For more information on configuring the

hydrator

mutator, you can refer to the [Ory Oathkeeper documentation on mutators](https://www.ory.sh/docs/oathkeeper/pipeline/mutator#hydrator). If you continue to face issues after making these adjustments, you might want to reach out to the Ory community or support channels for more specific assistance, as there might be a version-specific issue or a more complex configuration problem at play.

The error message you're seeing indicates that Ory Oathkeeper is expecting the

url

field in the

match_context

to be a structured

url.URL

object, but it's receiving a string instead. This is a more specific requirement than what I previously suggested. Let's adjust the response to meet this expectation. Here's how you should modify your API response:

json {     "subject": "653acd38f1e2e4b3a2d4e124",     "extra": {         "allowed_site_ids": [             "653acd38f1e2e4b3a2d4e201",             "653acd38f1e2e4b3a2d4e202"         ]     },     "header": {},     "match_context": {         "regexp_capture_groups": [],         "url": {             "Scheme": "http",             "Host": "<http://example.com|example.com>",             "Path": "/path"         }     } }

Key changes: - The

url

field in

match_context

is now an object representing a URL structure, rather than a string. - The URL object includes

Scheme

,

Host

, and

Path

fields, which correspond to the Go

url.URL

struct. If you don't have a specific URL to include, you can use empty strings for these fields:

json "url": {     "Scheme": "",     "Host": "",     "Path": "" }

This structure should match the Go

url.URL

type that Ory Oathkeeper is expecting, and should resolve the unmarshal error you're encountering. Remember to adjust your API to return this format. If you're using a language other than Go to generate this response, you'll need to ensure it produces a JSON object with this structure for the

url

field. For more information on the expected format and configuration of the

hydrator

mutator, you can refer to the [Ory Oathkeeper documentation on mutators](https://www.ory.sh/docs/oathkeeper/pipeline/mutator#hydrator). If you continue to face issues after making these changes, you might want to check your Ory Oathkeeper version and consult the specific documentation for that version, as the expected response format might vary between versions.
