The new master branch should point now to queens instead of pike. So, HOT templates should specify that they might contain features for queens release [1] [1]: https://docs.openstack.org/heat/latest/template_guide/hot_spec.html#queens Change-Id: I7654d1c59db0c4508a9d7045f452612d22493004

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:
|
|
servers:
|
|
type: json
|
|
# Note extra parameters can be defined, then passed data via the
|
|
# environment parameter_defaults, without modifying the parent template
