workflows:

  enable_ssh_admin:
    description: >-
      This workflow creates an admin user on the overcloud nodes,
      which can then be used for connecting for automated
      administrative or deployment tasks, e.g. via Ansible. The
      workflow can be used both for Nova-managed and split-stack
      deployments, assuming the correct input values are passed
      in. The workflow defaults to Nova-managed approach, for which no
      additional parameters need to be supplied. In case of
      split-stack, temporary ssh connection details (user, key, list
      of servers) need to be provided -- these are only used
      temporarily to create the actual ssh admin user for use by
      Mistral.
