Thanks for the suggestion Josh, that seems like a promising lead, I didn't
realize until now that add_host can *add host variables*, not just add
hosts to groups. Except that, so far, I'm not sure that it works to set
*new* host variables if the referenced host already existed in inventory.
I've tried this:
- name: Set hostvar aliases
add_host: >
name='{{ item }}'
zookeeper_myid='{{ hostvars[item].ec2_tag_ZooKeeperID }}'
zookeeper_bind_address='{{ hostvars[item].ec2_private_ip_address }}'
with_items: groups[zookeeper_ensemble_group]
which would get me what I'm wanting pretty readably, but it doesn't seem to
work.
I tried changing hash_behaviour to "merge" just to see if that could allow
this work, no dice. I'll have to dig further in implementation to
understand, and this issue might be relevant since the above is a local
action:
