description: >
  Example extra config for cluster config
  this example collects the hostname and MAC addresses for each node in
  the deployment, then distributes that info to all Controller nodes.

# Parameters passed from the parent template - note if you maintain
# out-of-tree templates they may require additional parameters if the
# in-tree templates add a new role.
parameters:
  controller_servers:
    type: json
  compute_servers:
    type: json
  blockstorage_servers:
    type: json
  objectstorage_servers:
    type: json
  cephstorage_servers:
    type: json
# Note extra parameters can be defined, then passed data via the
# environment parameter_defaults, without modifying the parent template
