1. Secure AI Model Registry with LDAP Integration in Keycloak

    Python

    To create a secure AI Model Registry with LDAP integration using Keycloak and Pulumi, you will need to do the following:

    1. Set up a new Keycloak Realm or use an existing one. The realm acts as a namespace for managing a set of users, roles, and groups, and their interactions with your applications.

    2. Configure LDAP Federation to connect your Keycloak instance to an LDAP server. This is crucial for enabling LDAP as a user store.

    3. Create a Client to define the entity that can request a login.

    4. Manage Roles and Groups to assign appropriate permissions to users.

    5. Use User role mapping to associate users with their roles, allowing for fine-grained access control.

    The following Pulumi program in Python uses the pulumi_keycloak provider to create resources for such a setup. Remember to replace any placeholder values with those corresponding to your environment and that your LDAP server details are correct.

    import pulumi import pulumi_keycloak as keycloak # Create a new Keycloak Realm realm = keycloak.Realm("ai-model-realm", realm="ai-model-realm", enabled=True) # Configure LDAP Federation: You need to provide specifics for your LDAP setup ldap_user_federation = keycloak.ldap.UserFederation("ldap-user-federation", realm_id=realm.id, name="MyLDAP", enabled=True, bind_dn="cn=manager,dc=example,dc=org", bind_credential="password", users_dn="ou=users,dc=example,dc=org", connection_url="ldap://ldap.example.org:389", import_enabled=True, # Automatically import LDAP users into Keycloak vendor="other") # Create a new client for the AI model registry client = keycloak.openid.Client("ai-model-registry-client", realm_id=realm.id, client_id="ai-model-registry", name="AI Model Registry", enabled=True, access_type="CONFIDENTIAL", standard_flow_enabled=True, direct_access_grants_enabled=True) # Define a Role for users to access the AI Model Registry role = keycloak.Role("registry-user-role", realm_id=realm.id, name="model-registry-user") # Managing Keycloak Groups is optional, depending on your use case group = keycloak.Group("registry-users-group", realm_id=realm.id, name="AI Model Registry Users") # If a specific user needs a role, map it here user_roles = keycloak.UserRoles("specific-user-roles", realm_id=realm.id, user_id="specific-user-id", # Replace with actual user ID role_ids=[role.id]) # Export the realm name and client credentials for use in your applications pulumi.export('keycloak_realm', realm.realm) pulumi.export('keycloak_client_id', client.client_id) # If you have the client secret, you can also export it or securely use it directly # pulumi.export('keycloak_client_secret', client_secret) # Replace with actual client secret retrieval method

    Explanation:

    • The keycloak.Realm resource creates a new Keycloak realm to contain our user base and other configuration settings.

    • The keycloak.ldap.UserFederation resource sets up a connection to an external LDAP directory which Keycloak will use to authenticate and import users.

    • With the keycloak.openid.Client, we're defining a client application that will communicate with Keycloak for authentication requests. Here we named it "AI Model Registry" to represent the software that will use this client.

    • The keycloak.Role and keycloak.Group resources are for assigning roles and grouping users, respectively, for access control to the AI Model Registry.

    • Finally, keycloak.UserRoles maps roles to specific users, giving them the rights they need to interact with protected resources.

    When you run this Pulumi program with the pulumi up command, it creates the infrastructure described in the code. Ensure all sensitive information like bind_credential for LDAP is handled safely and follows best practices, perhaps using Pulumi's secret management. Remember to replace placeholders like specific-user-id with real user identifiers from your user store or LDAP directory.

    After setting up, any service or application that needs to authenticate against Keycloak can use the client ID and possibly the client secret to establish trust with the Keycloak server and start the authentication process.

    The above Pulumi program assumes your environment is already configured for Keycloak, and doesn't cover every aspect of Keycloak's extensive feature set, such as setting up various authentication flows, protocols, or detailed LDAP mappings and synchronization. For more complex use cases, consult the Keycloak documentation and include additional configurations as necessary.
