Keycloak Configuration for Kubernetes Operator Installer

This topic describes the steps involved in configuring Keycloak before and after the Deploy installation. Keycloak is the default authentication manager for Deploy.

Intended Audience

This guide is for administrators who install and manage Digital.ai Deploy.

Before You Begin

• The Operator zip file is downloaded from the Deploy Software Distribution site and extracted to the standalone Deploy server you would use to install Deploy on the Kubernetes cluster.
• A local Deploy instance installed on your system. For information about how to set up local Deploy instance, see platform specific Operator-based installation topics.

Configuring Keycloak Parameters

To configure Keycloak as the default authentication manager for Digital.ai Deploy, go to digitalai-deploy/kubernetes folder of the Operator file and update the OIDC parameters in the daideploy_cr.yaml file.

Enabling OIDC Configuration

To enable external OIDC configuration on Digital.ai Deploy:

1. Set the oidc.enabled to true.

2. Set spec.keycloak.install to false.
   Note: By default, this value is set to true. If you want to use a different authentication provider other than Keycloak, set the value to false.

3. Configure the values for the OIDC parameters in the daideploy_cr.yaml file as described in the following table:

   Note: For more information about OIDC configuration, see Deploy OIDC with Keycloak.

Parameter	Description	Configuration
oidc.external	Is external configuration enabled	true
oidc.clientid	Client credentials from Deploy to Keycloak	clientId="" clientSecret=""
oidc.clientSecret
oidc.rolesClaimName	User property mappings	rolesClaimName=groups userNameClaimName="preferred_username"
oidc.userNameClaimName
oidc.issuer	URLs from Browser to Keycloak	issuer=http://keycloak:8080/auth/realms/digitalai-platform logoutUri=http://keycloak:8080/auth/realms/digitalai-platform/protocol/openid-connect/logout userAuthorizationUri=http://keycloak:8080/auth/realms/digitalai-platform/protocol/openid-connect/auth
oidc.logoutUri
oidc.userAuthorizationUri
oidc.postLogoutRedirectUri	URLs from Browser to Deploy	postLogoutRedirectUri=http://localhost:4516/login/external-login redirectUri=http://localhost:4516/login/external-login
oidc.redirectUri
oidc.accessTokenUri	URLs from Deploy to Keycloak	accessTokenUri=http://keycloak:8080/auth/realms/digitalai-platform/protocol/openid-connect/token keyRetrievalUri=http://keycloak:8080/auth/realms/digitalai-platform/protocol/openid-connect/certs
oidc.keyRetrievalUri
oidc.scopes	List of scopes (note single quotes around list, same way as in example)	'["openid"]'

Note: The path-based routing will not work if you use OIDC authentication. To enable path-based routing, you must modify the ingress specification in the daideploy_cr.yaml file as follows:

• Set the ingress.nginx.ingress.kubernetes.io/rewrite-target: /$2 to /
• Set ingress.path: /xl-release(/|$)(.*) to /

Note: if you have some missing values above, use "" for that value in the oidc object. Do not delete that value from the object.

Configuring Keycloak as the Default Authentication Manager

To configure Keycloak as the default authentication manager for Digital.ai Deploy, specify the values for the OIDC parameters in the the daideploy_cr.yaml as described in the following table:

Note:

• By default, Kubernetes Operator installer uses embedded Postgres database for Keycloak authentication.
• For more information about Keycloak authentication with External Database, see "Operator Based Solution with keycloak enabled with external database"

Parameter	Description	Default Value
keycloak.ingress.rules.host	Defines the valid DNS name for the Keycloak Ingress resource. This is a mandatory parameter. Note: By default, Keycloak pod uses the Postgres database that is included in the Operator installer. If you want to use an external database, create a database and a user, and ensure to update the parameters described in this table in the Keycloak section.	NA
DB_VENDOR	Defines the database vendor name. This is a mandatory parameter.	NA
DB_ADDR	Defines the database URI. This is a mandatory parameter.	NA
DB_PORT	Defines the port number. This is a mandatory parameter.	NA
DB_USER	Defines the username of the database user. This is a mandatory parameter.	NA
DB_PASSWORD	Defines the password of the database user. This is a mandatory parameter.	NA
spec.keycloak.install	Installs the Keycloak chart.	true
keycloak.extraENV KEYCLOAK_USER	Defines the username of the Keycloak user.	admin
keycloak.extraENV KEYCLOAK_PASSWORD	Defines the password of the Keycloak user.	admin

Do you want to use an existing Keycloak database with the Operator-based installer?

Note: This is not an officially supported use case. Use these instructions at your own discretion.

Use the following instructions to set up an existing Keycloak database, if you have been using an existing PostgreSQL database for Keycloak and if you want to use it while installing or upgrading Deploy using the Operator-based installer.

• Operator-based Fresh Installation
  • Edit the daideploy_cr.yaml file for setting up Keycloak with external database.
    • If you are using external database for both Deploy and Keycloak, update the values for the following parameters:
      • .spec.postgresql.install to false
      • .spec.keycloak.extraENV
        • DB_ADDR
        • DB_PORT
        • DB_USER
        • DB_PASSWORD
    • If you are using external database only for Keycloak and embedded Postgres database for Deploy, update the values for the following parameters:
      • .spec.keycloak.extraENV
        • DB_ADDR
        • DB_PORT
        • DB_USER
        • DB_PASSWORD
• Operator-based Upgrade

  • During the upgrade process, you need to use the custom operator zip option for setting up Keycloak with external database.

    Answer the following question while upgrading.

    • Do you want to use custom operator zip file for Deploy? Yes

    • ? Deploy operator zip to use (absolute path or URL to the zip)

  1. Download the operator zip from the Deploy Software Distribution site.
     • Extract the ZIP file to the DeployInstallation folder.
     • Update the following in daideploy_cr.yaml for setting up Keycloak with external database.
       • If you are using external database for both Deploy and Keycloak, update the values for the following parameters:
         • .spec.postgresql.install to false
         • .spec.keycloak.extraENV
           • DB_ADDR
           • DB_PORT
           • DB_USER
           • DB_PASSWORD
       • If you are using external database only for Keycloak and embedded Postgres database for Deploy, update the values for the following parameters:
         • .spec.keycloak.extraENV update the following fields.
           • DB_ADDR
           • DB_PORT
           • DB_USER
           • DB_PASSWORD
     • Zip the operator package and provide absolute path of the zip while upgrading [? Deploy operator zip to use (absolute path or URL to the zip)].
  2. If External database for Deploy is used, then during upgrade process we need to edit list of following question "Edit list of custom resource keys that will migrate to the new Deploy CR" and update the following parameters.
     • .spec.UseExistingDB.Enabled
     • .spec.UseExistingDB.XL_DB_URL
     • .spec.UseExistingDB.XL_DB_USER
     • .spec.UseExistingDB.XL_DB_PASS

Configuring User Permissions

As an admin, you can add user roles, assign role-based permissions, and configure Keycloak users with the required user roles.

To add user roles:

1. Log in to Digital.ai Deploy as admin, or a user with the Admin global permission.
2. From Explorer, click User Management > Roles > Add Role, and type the role. For example oidc-administrators.
3. Click Save.

To assign global permissions to the user role:

1. From Explorer, click User Management > Global Permissions, and select the checkboxes next to the user role (for example, oidc-administrators) to define the required permissions for the selected user role.

   

After assigning global permissions to the user role, to configure Keycloak users with this user role:

1. Log in to Keycloak as admin.

2. In the navigation pane, under Manage, click Users and select the user, for example — Alice.

3. From the Role Mapping tab, choose the role under Assigned Roles.

   

   Note: For information about the role, click Roles under Configure group.

Logging in to the Deploy Application

After configuring the parameters, you can verify the OIDC authentication by accessing the Deploy application.

1. In a web browser, enter the URL of the Deploy application.
   You will be redirected to the Keycloak Login screen.

   

2. If configured, enter the username and password for Deploy, or enter the default username and password (admin/admin).

   Note: After the successful configuration of Keycloak OIDC authentication, the default login credentials (admin/admin) will no longer work.

   After a successful authentication, you will be redirected to the Deploy dashboard.

Note:

• By default, the Operator comes with the default realm — digitalai-platform. You can use this realm to configure users and identity providers for Digital.ai products, such as Release and Deploy.
• To sign in as oidc-user, you can use the login credentials of any of the following sample users: alice, bob, carol, elrond, eve.
• If you want to sign in as an internal user, browse directly to http://example.com/login.
