Flask-Multipass-Keycloak 0.1.1

Flask-Multipass provider for Keycloak

Flask-Multipass-Keycloak

This package provides the keycloak authentication and identity providers for Flask-Multipass.

KeycloakAuthProvider This provider is a simple wrapper around AuthlibAuthProvider, since Keycloak works well with the standard authlib provider in flask-multipass.

KeycloakIdentityProvider This provider gives access to group information and members via Keycloak REST API.

Install

pip install flask-multipass-keycloak

Usage

Configuration

The configuration follows the standard Flask-Multipass way and the Keycloak specific part placed into the keycloak_args section.

MULTIPASS_AUTH_PROVIDERS = {
    'keycloak': {
        'type': 'keycloak',
        'title': 'Keycloak Auth Provider',
        'authlib_args': {...}
    }
}

MULTIPASS_IDENTITY_PROVIDERS = {
    'keycloak': {
        'type': 'keycloak',
        'title': 'Keycloak Identity Provider',
        'identifier_field': 'email',
        'keycloak_args': {
            'client_name': '<client_name>',
            'client_secret': '<client_secret>',
            'username': <username>,
            'password': <password>,
            'access_token_url': <access-token-url>,
            'realm_api_url': <realm-api-url>
        }
    }
}

Performance

The library needs to get an API access token from Keycloak which typically takes 200-300ms. Set the cache key of the multipass identity provider configuration to the import path of a Flask-Caching instance or a function returning such an instance, or the instance itself to enable caching of tokens (until they expire) and group data (30 minutes).

Development

In order to develop flask-multipass-keycloak, install the project and its dependencies in a virtualenv. This guide assumes that you have the following tools installed and available in your path:

• git (available in most systems)
• make (available in most systems)
• poetry (installation guide)
• pyenv (installation guide)

First, clone the repository locally with:

git clone https://github.com/unconventionaldotdev/flask-multipass-keycloak
cd flask-multipass-keycloak

Before creating the virtualenv, make sure to be using the same version of Python that the development of the project is targeting. This is the first version specified in the .python-version file and you can install it with pyenv:

pyenv install

You may now create the virtualenv and install the project with its dependencies in it with poetry:

poetry install
