DOCUMENTATION = """
author:
  - "Kenneth D. Evensen (@kevensen)"
deprecated:
  removed_in: "2.9"
  why: This module used the oc command line tool, where as M(openshift_raw) goes over the REST API.
  alternative: Use M(openshift_raw) instead.
description:
  - This module allows management of resources in an OpenShift cluster. The
    inventory host can be any host with network connectivity to the OpenShift
    cluster; the default port being 8443/TCP.
  - This module relies on a token to authenticate to OpenShift. This can either
    be a user or a service account.
