Keycloak as Auth Service in Kubernetes for AI Workloads
PythonTo deploy Keycloak as an authentication service in a Kubernetes cluster for AI workloads, you'll first need to have a Kubernetes cluster up and running. Whether you're using a managed Kubernetes service like Google Kubernetes Engine (GKE), Amazon Elastic Kubernetes Service (EKS), or Azure Kubernetes Service (AKS), or you're managing your own, the process with Pulumi will be similar.
For this use case, we'll use
pulumi_keycloak
to configure Keycloak resources. We'll create aRealm
,Client
, andUser
as basic examples of resources Keycloak requires to operate. Keycloak realms manage a set of users, credentials, roles, and groups. A client represents a client application that will interact with Keycloak. Users are individuals who can log in to the client application.To define these resources in your Pulumi application, you need to have the
pulumi_keycloak
provider installed and configured. Install the provider with Pulumi'spip
if you haven't done so:pip install pulumi_keycloak
Once you have the provider installed, you can write a Pulumi program to define your Keycloak configuration. Here is a simple illustration of defining a Keycloak Realm, a Client, and a User in a Python Pulumi program.
import pulumi import pulumi_keycloak as keycloak # Create a new Keycloak Realm keycloak_realm = keycloak.Realm('example-realm', realm='example', # This is the name of the realm enabled=True, ) # Create a new Keycloak Client within the Realm keycloak_client = keycloak.openid.Client('example-client', realm_id=keycloak_realm.id, client_id='example-app', # ID used for the client application name='Example App', # Human-readable name for the client enabled=True, client_authenticator_type='client-secret', protocol='openid-connect', access_type='CONFIDENTIAL', standard_flow_enabled=True, implicit_flow_enabled=False, direct_access_grants_enabled=True, valid_redirect_uris=['https://example.com/callback', 'https://example-app/auth'], ) # Create a new Keycloak User within the Realm keycloak_user = keycloak.User('example-user', realm_id=keycloak_realm.id, username='example-user', enabled=True, email='user@example.com', email_verified=True, firstName='Example', lastName='User', ) # Output the Realm and Client id so it can be easily accessed if needed pulumi.export('realm_id', keycloak_realm.id) pulumi.export('client_id', keycloak_client.id)
In the above program:
- We import the required modules.
- We create a new
Realm
called 'example'. Realms are the core concept in Keycloak as they partition the Keycloak server into multiple isolated units. - We create a new
Client
within that realm, which is a representation of your application that will be using Keycloak for authentication. - We create a new
User
within the realm, representing an individual who will be authenticated by Keycloak.
To apply this Pulumi program, run
pulumi up
in your command line in the same directory as your script.
