OpenStack control plane deployment is managed by openstackcontrolplane CR.
Use the following commands to view the OpenStackControlPlane CRD definition and specification schema:
oc describe crd openstackcontrolplane | more
oc explain openstackcontrolplane.specThe OpenStackControlPlane resources are created when the status is "Setup complete". Verify the status typing the following command:
oc get openstackcontrolplane -n openstackSample Output
NAME STATUS MESSAGE
openstack-galera-network-isolation True Setup completeConfirm that the control plane is deployed by reviewing the pods in the openstack namespace
oc get pods -n openstackSample Output
