Centralized Identity Management in AI Development with Keycloak

Question

Pulumi · Accepted Answer

When setting up centralized identity management for AI development, Keycloak is an excellent choice due to its flexibility, compatibility with various protocols like OpenID Connect and SAML, and a wide range of features. With Keycloak, you can easily manage users, roles, groups, and authentication flows.

To use Keycloak with Pulumi, you'll need to utilize the `pulumi_keycloak` package, which provides all necessary resources to manage Keycloak configurations as infrastructure as code. The following examples will demonstrate how to set up a basic Keycloak realm with a client, user, and group.

Before running the Pulumi program, ensure you have Pulumi installed and configured along with the Keycloak provider.

Let's dive into a Python program that demonstrates how to manage Keycloak's infrastructure using Pulumi:

1. **Keycloak Realm**: A realm in Keycloak manages a set of users, credentials, roles, and groups. Each user belongs to and logs into a realm.

2. **Keycloak Client**: This is an entity that can request Keycloak to authenticate a user. It's often equivalent to an application that wants to use Keycloak for its identity needs.

3. **Keycloak User and Group**: You manage individual users in Keycloak, as well as group them to apply common policies.

Here is the detailed Pulumi program:

```python
import pulumi
import pulumi_keycloak as keycloak

# Create a new Realm named 'ai-development'
ai_dev_realm = keycloak.Realm("ai-development",
    realm="ai-development", # This is the name of the realm. It must be unique.
    enabled=True,
    # Further configure the realm with additional arguments as needed.
)

# Define an OpenID Connect client
ai_dev_client = keycloak.openid.Client("ai-dev-client",
    realm_id=ai_dev_realm.id, # Link it to the created realm
    client_id="ai-dev-client", # Unique identifier for the client
    name="AI Development Client", # Human-readable name for the client
    enabled=True,
    access_type="CONFIDENTIAL", # Use 'CONFIDENTIAL' for server-side apps
    valid_redirect_uris=["http://localhost/callback"], # The URIs to redirect to after a login or logout 
    secret="clientSecret", # Define a client secret (use more secure way in production)
)

# Define a User in the realm
ai_dev_user = keycloak.User("ai-dev-user",
    realm_id=ai_dev_realm.id, # The realm this user belongs to
    username="devuser", # Unique username
    enabled=True,
    email_verified=True,
    initial_password=keycloak.UserInitialPasswordArgs(
        value="Password#1234", # The initial password for the user (use more secure way in production)
        temporary=False,
    )
)

# Define a User Group in the realm
ai_dev_group = keycloak.Group("ai-dev-group",
    realm_id=ai_dev_realm.id, # The realm this group belongs to
    name="AI Developers", # Name of the group
)

# Assign the user to the group
ai_dev_user_group_membership = keycloak.UserGroupMembership("ai-dev-user-group-membership",
    realm_id=ai_dev_realm.id, # The realm the relationship is in
    user_id=ai_dev_user.id, # ID of the user
    group_id=ai_dev_group.id, # ID of the group
)

# Expose the realm name and client ID as stack outputs
pulumi.export("realm_name", ai_dev_realm.realm)
pulumi.export("client_id", ai_dev_client.client_id)
```

In this program, we start by creating a Keycloak realm for our AI development environment. We then define a client within that realm that will be used by our application to interact with Keycloak. Following that, we create a Keycloak user and set an initial password for them. Lastly, we create a user group within the realm and add our user to this group.

By running this Pulumi program, you will provision the necessary Keycloak setup for centralized identity and access management in an AI development context. Remember to tailor these resources to align with your security practices, particularly around client secrets and user passwords.
