This issue was spotted during major upgrade where we had calls like
this:
servers: {get_param: servers, Controller}
These get_param calls are hanging indefinitely and make the whole
upgrade end in a timeout. We need to put brackets around the get_param
function when there are multiple arguments:
http://docs.openstack.org/developer/heat/template_guide/hot_spec.html#get-param
This is already done in most of the tree, and the few places where this
was not happening were parts not under CI. After this change the
following grep returns only one false positive:
grep -ir get_param: |grep -v -- '\[' |grep ','

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
