Configure Keycloak Identity Provider for Kubecost

OIDC is only officially supported on Kubecost Enterprise plans.

1. Create a new Keycloak Realm.

2. Navigate to Realm Settings > General > Endpoints > OpenID Endpoint Configuration > Clients.

3. Select Create to add Kubecost to the list of clients. Define a clientID. Ensure the Client Protocol is set to openid-connect.

4. Select your newly created client, then go to Settings.

   1. Set Access Type to confidential.

   2. Set Valid Redirect URIs to http://YOUR_KUBECOST_ADDRESS/model/oidc/authorize.

   3. Set Base URL to http://YOUR_KUBECOST_ADDRESS.

The .Values.oidc for Keycloak should be as follows:

oidc:
  enabled: true
  # This should be the same as the `clientID` set in step 3 above
  clientID: "YOUR_CLIENT_ID"
  # Find this in Keycloak UI by going to your Kubecost client, then clicking on "Credentials".
  clientSecret: "YOUR_CLIENT_SECRET"
  # The k8s secret where clientSecret will be stored
  secretName: "kubecost-oidc-secret"
  # The login endpoint for the auth server
  authURL: "http://YOUR_KEYCLOAK_ADDRES/realms/YOUR_REALM_ID/protocol/openid-connect/auth?client_id=YOUR_CLIENT_ID&response_type=code"
  # Redirect after authentication
  loginRedirectURL: "http://YOUR_KUBECOST_ADDRESS/model/oidc/authorize"
  # Navigate to "Realm Settings" -> "General" -> "Endpoints" -> "OpenID Endpoint Configuration". Set to the discovery URL shown on this page.
  discoveryURL: "YOUR_DISCOVERY_URL"
