In case someone else has this issue, for my post task I that I only want to
run on the last host I used the below conditional. Results in skipped tasks
but it does accomplish the goal. Not sure if there is a more elegant way to
say run on the last host.
when: inventory_hostname == ansible_play_hosts[ ansible_play_hosts | length
- 1]
This results in
