BC> you can still access it via hostvars['hostitwassetin']['foo_first_host']
Ja, but how do I know (when I'm the second host) who the first host was?
In my actual use case, I'm doing things like restarting a cluster of
appservers, and I want to pause after the first, and then just do the rest
without further prompting (but one at a time, so I don't want the
(otherwise super cool) new serial: [1, "100%"] business).
FWIW, the add_host trick seems to work:
- hosts: all
serial: 1
tasks:
- debug: var=groups['foo_completed_hosts']
- name: pause after the first host (expect "skipping" for subsequent
hosts)
pause:
prompt: Pausing after the first host; hit return to do the rest
when: "'foo_completed_hosts' not in groups"
- add_host: name={{ inventory_hostname }} groups=foo_completed_hosts
So, if there's not a way to set a global variable, the add_host way seems ok.
