tried to use the feature in an existing playbook with multi-master jails and i wasn't able to limit the configuration to the jails of a given host.

is this still missing as a feature or am i missing how to use it?

or do i need to define explicit, separate groups for each ez-master?

[fschulze]

Try the inventory command to see which groups are defined and which instances belong where.

I guess we would need a way to apply set operations for groups. Not sure if ansible already supports something like that where we could take a look.

well, the inventory shows the group with members of all ezmasters, so i can either apply the configuration to all hosts or none, which is not very useful...

perhaps ploy_ansible would have to create the 'secondary' groups explicitly for each master?

i.e. currently the following scenario

[ez-instance:foo]
ip = 10.0.0.11
master =  staging production
groups = mygroup

[ez-instance:bar]
ip = 10.0.0.12
master =  staging production
groups = mygroup

gives an inventory of

mygroup
  staging-foo
  staging-bar
  production-foo
  production-bar

there's actually nothing wrong with that, what we would need additionally is to generate the following groups:

staging-mygroup
  staging-foo
  staging-bar

production-mygroup
  production-foo
  production-bar

do you think that approach could work?
