Launching a deployment template with stateful services on an external cluster, does not list the volume policies in step 2 of the launch wizard.
An external GKE cluster has been registered with gopaddle. In Step 1 of the launch wizard, the external cluster is chosen for deployment.
In step 2 of the launch wizard, for each volume label in the stateful services, if the volume type is chosen as "Dynamic Volume", then 'No volume policy found' message is displayed. However there are GCE based volume policies available in the Provision Policies under "Storage Policies" section.
Though the external cluster is of type GKE, GCE based provision policies cannot be used to dynamically provision the persistent volumes. Instead an NFS provision policy can be used to dynamically provision persistent volumes on external clusters.
