Adopting the {dashboard_service}

To adopt the {dashboard_first_ref}, you patch an existing OpenStackControlPlane custom resource (CR) that has the {dashboard_service} disabled. The patch starts the service with the configuration parameters that are provided by the {rhos_prev_long} environment.

Prerequisites

You adopted Memcached. For more information, see Deploying back-end services.
You adopted the {identity_service_first_ref}. For more information, see Adopting the {identity_service}.

Procedure

Patch the OpenStackControlPlane CR to deploy the {dashboard_service}:

oc patch openstackcontrolplane openstack --type=merge --patch '
spec:
  horizon:
    enabled: true
    apiOverride:
      route: {}
    template:
      memcachedInstance: memcached
      secret: osp-secret
'

Verification

Verify that the {dashboard_service} instance is successfully deployed and ready:
```
oc get horizon
```

Confirm that the {dashboard_service} is reachable and returns a 200 status code:

PUBLIC_URL=$(oc get horizon horizon -o jsonpath='{.status.endpoint}')
curl --silent --output /dev/stderr --head --write-out "%{http_code}" "$PUBLIC_URL/dashboard/auth/login/?next=/dashboard/" -k | grep 200
