It looks like we do not have the openshift-origin namespace, and do not have a working ReplicationController.
Currently I do not consider this a complete OpenShift deployment.

I assume I am missing the --server-key option.

I use k8s on Google's GKE. Do I have to generate that key, or is it a pre-created key?

This is a Python 2 vs Python 3 error, but it also looks like your file is missing.

You need to SSH into your kube master and grab /srv/kubernetes/serviceaccount.key (off the top of my head, the path might be slightly different) and pass the path to that with --server-key

Create-volume is a extremely alpha feature and will only work on the newest builds of kubernetes. You can manually make a pv and pass the name of it if you want to use an old cluster version.

I'll work on adding better detection for these errors before the script actually makes anything.
