Keycloak Identity Brokering for Federated AI Services

Question

Pulumi · Accepted Answer

Identity Brokering in Keycloak allows you to connect Keycloak with external Identity Providers (IdPs) so that users can be authenticated against those external IdPs. The term "federated" refers to the idea that users from different domains or organizations can use their existing identities to access shared services or systems, such as AI services or applications.

To accomplish this with Pulumi, you could define a Keycloak Identity Provider resource in your Pulumi program. You have to choose the type of IdP you are working with (e.g., SAML, OpenID Connect) and configure it accordingly within your Keycloak realm.

Let's assume you want to set up a SAML Identity Provider in Keycloak for your federated AI services. Below is a Pulumi program written in Python that demonstrates how you might configure such an identity provider:

1. Set up a Keycloak SAML Identity Provider.
2. Configure the properties required by the SAML Identity Provider, like `entityId` and `singleSignOnServiceUrl`.
3. Define any additional configurations that are relevant to your setup, such as `syncMode`, `trustEmail`, etc.

The following is a detailed Pulumi program example that sets up identity brokering in Keycloak for federated AI services:

```python
import pulumi
import pulumi_keycloak as keycloak

# Create a Keycloak SAML Identity Provider within a specific Keycloak realm.
saml_identity_provider = keycloak.saml.IdentityProvider("saml-idp",
    # Alias for the identity provider
    alias="ai-service-idp",
    # Realm in which this identity provider will be created. Replace with your realm name.
    realm="my-realm",
    # Whether this identity provider is enabled.
    enabled=True,
    # The Entity ID of the SAML Identity Provider.
    entityId="http://idp.example.com/",
    # The SSO URL of the SAML Identity Provider where Keycloak redirects for authentication.
    singleSignOnServiceUrl="http://idp.example.com/sso",
    # Specifies how to synchronize user data from the external IdP.
    syncMode="IMPORT",
    # If true, Keycloak will trust the email claim without validation.
    trustEmail=False,
    # Additional configurations can go here.
)

# Export the IdP configuration details, typically URLs or IDs that can be used by applications.
pulumi.export("idp_alias", saml_identity_provider.alias)
pulumi.export("sso_service_url", saml_identity_provider.singleSignOnServiceUrl)

```

In the program above:

- We are creating a SAML identity provider within a Keycloak realm using the `pulumi_keycloak.saml.IdentityProvider` resource.
- The `alias` attribute is a unique identifier for the IdP within the realm.
- The `enabled` attribute toggles whether this IdP is active.
- The `entityId` is the identity provider's unique ID - often the IdP's URL.
- The `singleSignOnServiceUrl` is the URL for the SAML SSO service provided by the identity provider.
- The `syncMode` dictates how Keycloak will synchronize users. Here it is set to "IMPORT" meaning that users will be imported into Keycloak upon first login.
- The `trustEmail` attribute, if set to True, means that Keycloak will trust the email provided by the IdP without further validation.

After defining your resources, you can run this pulumi program by:
- Installing the required Pulumi Python packages.
- Setting up the Keycloak provider credentials.
- Running `pulumi up` in your terminal.

This will apply the configuration to your Keycloak instance and output the alias and the SSO service URL for the configured identity provider, which you can use to integrate with your federated AI services.

Remember that the specific settings and configurations will largely depend on the actual setup and requirements of your federated identity management and the external IdPs you plan to integrate.
