Sure, I can guide you through the process of setting up Ory Kratos on your local machine using Docker. Here are the steps: 1. Prerequisites: You will need Git, Docker, and Docker Compose installed on your system. Make sure that Docker has enough disk space. You can check the remaining disk space using

docker system df

. If the volumes are above the 85% threshold, prune old Docker objects before you start. 2. Clone Ory Kratos: Clone the Ory Kratos repository and navigate into it using the following commands:

git clone <https://github.com/ory/kratos.git>       cd kratos       git checkout master

3. Run Ory Kratos in Docker: Run the following command to start Ory Kratos using Docker Compose:

docker-compose -f quickstart.yml -f quickstart-standalone.yml up --build --force-recreate

If you have SELinux, run:

docker-compose -f quickstart.yml -f quickstart-selinux.yml -f quickstart-standalone.yml up --build --force-recreate

4. Check the logs: Once the output slows down and logs indicate a healthy system, you're ready to go. A healthy system will show something along the lines of:

kratos_1 | time="2020-01-20T14:52:13Z" level=info msg="Starting the admin httpd on: 0.0.0.0:4434"       kratos_1 | time="2020-01-20T14:52:13Z" level=info msg="Starting the public httpd on: 0.0.0.0:4433"

5. Important considerations: Make sure that ports

4455

,

4433

,

4434

, and

4436

are free. Always use

127.0.0.1

as the hostname; never use

localhost

! This is important because browsers treat these two as separate domains and will therefore have issues with setting and using cookies. For more detailed instructions, you can refer to the [official Ory Kratos Quickstart guide](https://www.ory.sh/docs/kratos/quickstart#clone-ory-kratos-and-run-it-in-docker).

Sure, I can guide you through the process of setting up Ory Kratos on your local machine using Docker and PostgreSQL, and then using the Python SDK for your Django project. Here are the steps: 1. Prerequisites: You will need Git, Docker, and Docker Compose installed on your system. Make sure that Docker has enough disk space. You can check the remaining disk space using

docker system df

. If the volumes are above the 85% threshold, prune old Docker objects before you start. 2. Clone Ory Kratos: Clone the Ory Kratos repository and navigate into it using the following commands:

git clone --depth 1 --branch master <https://github.com/ory/kratos.git>       cd kratos       git checkout master       git pull -ff

3. Install PostgreSQL: Install PostgreSQL by running the following commands:

sudo apt install postgresql postgresql-contrib -y       sudo -i -u postgres

Create the database and a user for Kratos:

createdb kratos       CREATE USER kratos PASSWORD '<YOUR_PASSWORD_HERE>';       GRANT CONNECT ON DATABASE kratos to kratos;

Change the default password encryption to a stronger one and reload the configuration:

psql       ALTER SYSTEM SET password_encryption = 'scram-sha-256';       SELECT pg_reload_conf();

Check your credentials against PostgreSQL:

psql -U kratos -W -h 127.0.0.1

4. Run Ory Kratos in Docker: Run the following command to start Ory Kratos using Docker Compose:

docker-compose -f quickstart.yml -f quickstart-standalone.yml -f quickstart-postgres.yml up --build --force-recreate

5. Python SDK: Unfortunately, as of the current knowledge sources provided, there is no specific Python SDK for Ory Kratos. However, you can interact with the Ory Kratos API using any HTTP client library in Python, such as

requests

. For more detailed instructions, you can refer to the [official Ory Kratos Quickstart guide](https://www.ory.sh/docs/kratos/quickstart#clone-ory-kratos-and-run-it-in-docker) and the [PostgreSQL setup guide](https://www.ory.sh/docs/kratos/guides/deploy-kratos-example#install-postgresql).

Yes, Ory Kratos will store user data in the PostgreSQL database you created. When you set up Ory Kratos, you specify the database connection details in the configuration file (

kratos.yml

). In the configuration file, you set the

dsn

(Data Source Name) to point to your PostgreSQL database. For example:

yaml dsn: <postgres://kratos:[email> protected]:5432/kratos?sslmode=disable&max_conns=20&max_idle_conns=4

This tells Ory Kratos to use your PostgreSQL database (

kratos

) running on

localhost

on port

5432

. The username (

kratos

) and password (

<YOUR_PASSWORD_HERE>

) are also specified in the connection string. Once Ory Kratos is running, it will use this database to store user identities, credentials, and other related data. You can find more details in the [Ory Kratos PostgreSQL setup guide](https://www.ory.sh/docs/kratos/guides/deploy-kratos-example#install-postgresql) and the [Ory Kratos installation guide](https://www.ory.sh/docs/kratos/guides/deploy-kratos-example#install-ory-kratos).

The

kratos.yml

configuration file is located in the Ory Kratos repository that you cloned. Specifically, you can find it in the

contrib/quickstart/kratos/email-password/

directory. Here is the direct link to the file on GitHub: [kratos.yml](https://github.com/ory/kratos/blob/master/contrib/quickstart/kratos/email-password/kratos.yml) Remember to replace the placeholders in the configuration file with your actual values, such as the database connection details.

The

email protected

part in the

dsn

string is a placeholder for the password of the PostgreSQL user. It's not actually related to email protection. In your case, you should replace it with the password you set for the

kratos

user in PostgreSQL. So if your password was

mysecretpassword

, the

dsn

string would look like this:

yaml dsn: <postgres://kratos:mysecretpassword@localhost:5432/kratos?sslmode=disable&max_conns=20&max_idle_conns=4>

This string tells Ory Kratos to connect to a PostgreSQL database named

kratos

on

localhost

port

5432

using the username

kratos

and the password

mysecretpassword

. The

sslmode=disable

part disables SSL for the connection, and

max_conns=20

and

max_idle_conns=4

set the maximum number of total and idle connections to the database, respectively.

No, you don't need to change the

quickstart-postgres.yml

file. This file is used by Docker Compose to set up the services required for the quickstart, including the PostgreSQL database. The

quickstart-postgres.yml

file is designed to work with the default settings in the

kratos.yml

configuration file. If you've changed the database connection details in

kratos.yml

(for example, if you're using a different database name, user, or password), you'll need to update the

quickstart-postgres.yml

file to match. However, if you're using a local PostgreSQL database that you've set up yourself (as it seems from your previous questions), you don't need the

quickstart-postgres.yml

file at all. The

docker-compose -f quickstart.yml -f quickstart-standalone.yml up --build --force-recreate

command should be enough to start Ory Kratos. Remember to set the

dsn

in

kratos.yml

to point to your local PostgreSQL database. For example:

yaml dsn: <postgres://kratos:mysecretpassword@localhost:5432/kratos?sslmode=disable&max_conns=20&max_idle_conns=4>

Replace

mysecretpassword

with the actual password for your

kratos

PostgreSQL user.

This error message indicates that Docker is unable to connect to the Docker registry at

<http://registry-1.docker.io|registry-1.docker.io>

on port

443

. This could be due to a network issue, a DNS resolution problem, or a firewall blocking the connection. Here are a few things you can try to resolve this issue: 1. Check your internet connection: Make sure your internet connection is working properly. You can test this by trying to access

<https://registry-1.docker.io>

in a web browser. 2. Check your DNS settings: Docker uses your system's DNS settings by default. If you're having DNS resolution issues, you might need to specify custom DNS servers for Docker. You can do this by editing the Docker daemon configuration file (usually located at

/etc/docker/daemon.json

) and adding the following:

json     {       "dns": ["8.8.8.8", "8.8.4.4"]     }

This sets Docker to use Google's public DNS servers. 3. Check your firewall settings: If you're using a firewall, make sure it's not blocking connections to

<http://registry-1.docker.io|registry-1.docker.io>

on port

443

. The exact steps to do this depend on which firewall software you're using. 4. Restart Docker: Sometimes, simply restarting Docker can resolve connection issues. You can do this by running

systemctl restart docker

(on Linux) or by clicking "Restart Docker" in the Docker Desktop menu (on Windows and macOS). If none of these steps resolve the issue, you might want to reach out to your network administrator or internet service provider for further assistance.

The Ory Kratos quickstart guide uses a fake SMTP server for sending emails, which means the emails won't actually be delivered to your inbox. Instead, you can view the emails by opening the MailSlurper UI at

<http://127.0.0.1:4436>

. Here's how you can retrieve the email: 1. Open your web browser and navigate to

<http://127.0.0.1:4436>

. 2. You should see the MailSlurper UI, which will display the emails sent by the system. 3. Look for the verification email and click the verification link. If you don't see the email, try refreshing the page or clicking on the home icon in the menu bar. For more information, refer to the [Ory Kratos Quickstart guide](https://www.ory.sh/docs/kratos/quickstart#email-verification-part-1).

Ory Kratos does store user data in the database you specify in the configuration file. However, if you're not seeing any data in your PostgreSQL database, there could be a few reasons for this: 1. Database Connection: Ensure that the

dsn

in your

kratos.yml

configuration file is correctly pointing to your PostgreSQL database. The format should be

<postgres://username:password@localhost:5432/database_name>

. 2. Database User Permissions: Make sure the database user specified in the

dsn

has the correct permissions to read and write to the database. 3. Table Names: Ory Kratos creates tables with specific names in your database. The user data is stored in a table named

identities

. Make sure you're checking the correct table. 4. Data Commit: If you're checking the database while Kratos is still running, it's possible that the data hasn't been committed yet. Try stopping Kratos and then check the database again. If you're still not seeing any data, it might be helpful to check the logs produced by Ory Kratos for any error messages related to database connections or operations.
