In Ory Keto, namespaces are defined using the Ory Permission Language (OPL), which is a subset of TypeScript. Here's an example of how you can define namespaces:

typescript import { Namespace, Context } from "@ory/keto-namespace-types"      class User implements Namespace {}   class Document implements Namespace {}   class Folder implements Namespace {}

Each namespace holds a set of permissions, which define which relationships are checked. For example, checking a

view

permission for

User:bob

on an

readme.txt

file in the

Document

namespace requires the following relationship lookups:

typescript is User:bob in viewers of Document:readme.txt // all viewers can view the document   is User:bob in editors of Document:readme.txt // all editors can view the document   is User:bob in owners of Document:readme.txt // all owners can view the document

The permission model defines which relationships are checked in the process. You can learn more about creating a permission model in the [Ory documentation](https://www.ory.sh/docs/keto/modeling/create-permission-model). Please note that the code snippets provided are written in TypeScript, which is the language used for defining permissions in Ory Keto. If you're using a self-hosted Ory Keto, you'll need to have a TypeScript environment set up to use this code. Source: [Ory Documentation](https://www.ory.sh/docs/keto/concepts/namespaces)

Based on the provided extracts, there is no direct command to create a namespace through the command line in Ory Keto. Namespaces are defined using the Ory Permission Language (OPL), which is a subset of TypeScript. This is typically done within the code of your application or service, rather than directly through the command line. However, there is a command

keto namespace

in the Ory Keto CLI that is used to read and manipulate namespaces. The specific options for this command are:

-h, --help help for namespace    -c, --config strings Config files to load, overwriting in the order specified. (default [/home/runner/keto.yml])

Please note that the

keto namespace migrate up

command is deprecated and is not required anymore. For more information, you can refer to the [Ory Keto CLI documentation](https://www.ory.sh/docs/keto/cli/keto-namespace).

To configure a self-hosted Ory Kratos to provide login service for a self-hosted Ory Hydra, you need to set up the appropriate URLs in the configuration files of both services. In Ory Hydra, you need to set the

hydra.config.urls.login

and

hydra.config.urls.consent

to point to your Ory Kratos instance. This can be done in the Hydra configuration file or via environment variables. Here is an example of how to set these values in the Hydra configuration file:

yaml hydra:   config:     urls:       login: <https://my-kratos-instance/login>       consent: <https://my-kratos-instance/consent>

In Ory Kratos, you need to set the

selfservice.flows.login.ui_url

to point to your login UI. This can be done in the Kratos configuration file. Here is an example of how to set this value:

yaml selfservice:   flows:     login:       ui_url: <http://127.0.0.1:4455/auth/login>

Please note that the actual URLs will depend on your specific setup. Sources: - [Ory Hydra Configuration](https://www.ory.sh/docs/hydra/self-hosted/kubernetes-helm-chart) - [Ory Kratos Configuration](https://www.ory.sh/docs/kratos/self-service/flows/user-login)

To configure a self-hosted Ory Kratos to provide login service for a self-hosted Ory Hydra with your own UI interface, you need to set up the appropriate URLs in the configuration files of both services. In Ory Hydra, you need to set the

oauth2/urls/login

and

oauth2/urls/consent

to point to your Ory Kratos instance. This can be done in the Hydra configuration file. Here is an example of how to set these values:

yaml oauth2:    urls:    consent: <http://localhost:3000/consent>    login: <http://localhost:3000/login>

You can update the project configuration using the file you worked with:

bash ory update oauth2-config <project-id> --file config.yaml

In Ory Kratos, you need to set the

selfservice.flows.login.ui_url

to point to your login UI. This can be done in the Kratos configuration file. Here is an example of how to set this value:

yaml selfservice:    flows:    login:    ui_url: <http://127.0.0.1:3000/auth/login>

Please note that the actual URLs will depend on your specific setup. Sources: - [Configure Ory Network](https://www.ory.sh/docs/hydra/guides/custom-ui-oauth2) - [Ory Kratos Configuration](https://www.ory.sh/docs/kratos/self-service/flows/user-login)

@chilly-king-10285 Can you tell me the full process of self-hosted ory kratos + ory hydra, starting from the frontend calling the login api

Sure, here's a high-level overview of how you can use a self-hosted Ory Kratos and Ory Hydra together, starting from the frontend calling the login API: 1. Frontend Calls the Login API: The frontend initiates the process by calling the Ory Hydra's OAuth 2.0 Authorization endpoint. This will redirect the user to the login provider, which is Ory Kratos in this case. 2. Ory Kratos Handles the Login Request: Ory Kratos handles the login request by presenting the user with a login form. This can be a custom form that you've built or a form provided by Ory Kratos. 3. User Submits the Login Form: The user fills out the login form and submits it. Ory Kratos verifies the user's credentials. 4. Ory Kratos Redirects to Ory Hydra: If the login is successful, Ory Kratos redirects the user back to Ory Hydra along with a login challenge. 5. Ory Hydra Handles the Login Challenge: Ory Hydra verifies the login challenge and if it's valid, it issues an authorization code to the user. 6. Frontend Exchanges Authorization Code for Tokens: The frontend exchanges the authorization code for access and refresh tokens by calling Ory Hydra's OAuth 2.0 Token endpoint. 7. Frontend Uses the Tokens: The frontend can now use the access token to make authenticated requests to your API on behalf of the user. Here's an example of how you can initiate the login flow from your frontend:

javascript // Redirect the user to the Ory Hydra's OAuth 2.0 Authorization endpoint window.location.href = '<https://your-hydra-instance/oauth2/auth?client_id=your-client-id&redirect_uri=your-redirect-uri&response_type=code&scope=openid+offline>';

Please note that the actual URLs and parameters will depend on your specific setup.
