Add one more step (task) to containers download/upload sequence - copy saved .tar containers to ansible host (delegate_to: localhost). Then upload images to target nodes. It uses synchronize module so if ansible host (localhost) is the same host as kube-master[0] then new task causes no issues and the copy to localhost process is basically skipped.
