the name of the Ansible group denoting the collection of alls hosts participating as either agents or servers in the Consul network. consul_agent_server_group_name denotes those hosts that are voting members in the Consul consensus. These two role vars are a convenient degree of freedom when you're managing multiple Consul clusters within a single large inventory.

This variable is set on the role level and not uses in tasks. What would be a use case?

andrewrothstein commented 6 years ago

It's set at the role level. It's referenced in the vars which are referenced in the tasks as well as the templates for every host.

Let me be more precise about my question - consul_agent_group_name is not used:

$ git clone https://github.com/andrewrothstein/ansible-consul-cluster
$ grep consul_agent_group_name -r ansible-consul-cluster
ansible-consul-cluster/defaults/main.yml:consul_agent_group_name: consul

I'm interested in the idea of having two inventory groups consul_agent_server_group_name and consul_agent_group_name, but still don't see how this would work in practice.
