1. Secure AI Service Gateways with OpenID Connect Clients


    To establish a secure AI service gateway with OpenID Connect clients, you'll need to integrate OpenID Connect (OIDC) authentication with your service gateway. OIDC is an authentication layer on top of OAuth 2.0, which allows clients to verify the identity of the end user and to obtain basic profile information about the end user in an interoperable and REST-like manner.

    Let's assume you want to use Keycloak, which is an open-source Identity and Access Management solution aimed at modern applications and services. With Keycloak, you can set up OIDC clients which integrate with your existing service gateways, such as API Gateways from cloud provides like AWS, Azure, or GCP.

    Here we will use Pulumi to create an OIDC client in Keycloak to be used by an API Gateway. This program doesn't cover the setup of API Gateway itself but focuses on creating and configuring an OIDC client, which is a necessary step for securing your gateways.

    Before running this Pulumi program, you must have access to a Keycloak server and ensure you have configured the Pulumi Keycloak provider correctly with the necessary credentials.

    Below is a Pulumi program in Python that demonstrates how to create an OpenID Connect client in Keycloak:

    import pulumi import pulumi_keycloak as keycloak # Create a new OpenID Connect client in Keycloak # This client will be used to secure our AI services by providing an authentication layer. oidc_client = keycloak.openid.Client("ai-service-gateway-client", realm_id="your_realm", # Replace with the ID of the Keycloak realm client_id="ai-service-client-id", # Replace with your desired client ID name="AI Service Gateway Client", # Name of the OIDC client description="Client for securing AI service gateways with OIDC", enabled=True, # Enables this client to communicate with the server client_authenticator_type="client-secret", # Type of client authentication # Replace with the desired base URL for your AI services root_url="https://ai-service.yourdomain.com", redirect_uris=[ "https://ai-service.yourdomain.com/*", # Redirect URI for your service ], web_origins=[ "*", # Define the allowed web origins ], standard_flow_enabled=True, # Enable the standard OIDC flow direct_access_grants_enabled=True, # Enable direct access grants (resource owner password credentials grant) # The 'access type' of the client - can be 'CONFIDENTIAL' if it requires the client secret on the token endpoint. access_type="CONFIDENTIAL", ) # Export the client ID and secret for use in your gateway configuration pulumi.export('client_id', oidc_client.client_id) pulumi.export('client_secret', oidc_client.client_secret) # The secret value will be automatically encrypted by Pulumi when viewing outputs.

    This program defines an OIDC client with the necessary properties that you can adjust to match your application's requirements. After creating the OIDC client, it exports the client ID and secret. You'll use these credentials to configure your AI service gateway (like an API Gateway) to use OIDC for authentication.

    Remember, the code assumes that you have a Keycloak realm already set up. Replace the placeholder values in the realm_id, client_id, and root_url with your actual Keycloak realm ID, your desired OIDC client ID, and the base URL of your AI services.

    After running this Pulumi program with pulumi up, the Keycloak OIDC client is created and the associated credentials are printed as outputs, which you should securely inject into your AI service gateway's authentication configuration. The client secret is encrypted in the output for security purposes.
