Comment 2 for bug 1700039

You picket also the change to add docker_volume_type. That is the reason the conductor fails.

You have two options:
Option 1: Revert the code to ocata without the cherry-picked change and then create the kubernetes dashboard manually. You can either take the manifests from here [1] or here [2].

Option 2: To fix you modified ocata version you could remove these lines [3][4] and add default: "" in [5].
