Example extra config for cluster config
|
|
|
|
this example deploys a random string to all controller and compute
|
|
|
|
nodes, showing how data may be shared amongst nodes, vs the
|
|
|
|
other ExtraConfig interfaces which act only on individual 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.
