NOTE: The deployment still goes through despite the python error that's trown. The same workd on OCP 3.5+

ValueError: Invalid value for available_replicas, must not be None

available_replicas is a key of the V1DeploymentConfigStatus which is the body for the 'status' key in the V1DeploymentConfig object. That status key however is supposed to be optional

[ceridwen]

This is the same underlying issue as #139 and kubernetes-client/python#394, an API call that returns null and then crashes because of new validation code in 4.0 client.

Fixed by (#167) you will need to use the Dynamic Client (https://github.com/openshift/openshift-restclient-python#dynamic-client-usage) to get the fix.
