1. Keycloak Roles for Multi-Tenant AI Platform Access Management


    In a multi-tenant AI platform, access management is crucial to ensure that only authorized users can access specific resources and perform certain operations. Keycloak is a popular open-source identity and access management solution that can handle multi-tenancy quite effectively.

    We will use Pulumi to script the creation of roles in Keycloak that could be used for a multi-tenant AI platform. We'll define different roles that could represent different levels of access to the system, such as admin, developer, and user. These roles can be assigned to users within specific realms, which represent different tenants within the platform.

    The following Pulumi program uses the pulumi_keycloak provider to create roles within a Keycloak realm. I'm going to break down what each part of the program does:

    1. Keycloak Provider: Set up the Keycloak provider to manage resources within Keycloak.
    2. Roles: Create different roles that can be assigned to users or groups within a realm.
    3. User Roles: Associate a user with specific roles within a realm.
    4. Default Roles: Optionally, you can set default roles that every new user within the realm would inherit.
    5. Export: At the end, we will export some important identifiers that can be used to interact with or reference these roles within an application.

    Let's write the Pulumi program in Python. Make sure you have already set up your Keycloak instance and Pulumi environment before running this script.

    import pulumi import pulumi_keycloak as keycloak # Configure the Keycloak provider provider = keycloak.Provider('keycloak-provider', client_id='admin-cli', client_secret='secret', realm='master', url='https://keycloak.example.com/') # Replace 'your-realm' with the actual name of the Keycloak realm you want to work within. realm_id = 'your-realm' # Define roles for the AI platform admin_role = keycloak.Role('admin-role', realm_id=realm_id, name='admin', description='Admin role with all privileges' ) developer_role = keycloak.Role('developer-role', realm_id=realm_id, name='developer', description='Developer role with limited privileges' ) user_role = keycloak.Role('user-role', realm_id=realm_id, name='user', description='User role with basic privileges' ) # Assuming we already have a list of users # and we want to assign them their respective roles # The 'user_ids' list should be replaced with actual Keycloak user IDs user_ids = ['user-id-1', 'user-id-2'] for user_id in user_ids: keycloak.UserRoles('user-roles-{}'.format(user_id), realm_id=realm_id, user_id=user_id, role_ids=[ admin_role.id, developer_role.id, user_role.id ] ) # Set the 'user' role as a default role for all new users within the realm default_roles = keycloak.DefaultRoles('default-user-roles', realm_id=realm_id, default_roles=[user_role.name] ) # Export the role IDs which can be used to assign these roles to the users via API or Keycloak Admin Console pulumi.export('admin_role_id', admin_role.id) pulumi.export('developer_role_id', developer_role.id) pulumi.export('user_role_id', user_role.id)

    In this program:

    • We define three roles: admin, developer, and user. Each role has a name and a description which helps to identify the purpose and level of access the role grants within the platform.
    • We loop through a list of user IDs and assign all the roles to each user. In a real-world case, you would likely have logic to determine which roles to assign to each user.
    • We set the user role as a default role for the realm, so all new users will automatically get this role.
    • Finally, we export the IDs of the roles. This can be useful when you need to manage these roles programmatically, like via API or integrating with other systems.

    Please replace placeholder values such as 'your-realm', 'admin-cli', 'secret', 'https://keycloak.example.com/', and 'user-id-1', 'user-id-2' with actual values from your Keycloak setup. The realm_id should be the ID of the realm where you want to create these roles.
