I'm looking for some tips on the best way to store a variable persistently
across all hosts or multiple plays.
I am attempting to create a docker swarm manager using something similar to
this:
1. - hosts: swarm-init
2. gather_facts: no
3. tasks:
4. - shell: docker swarm init
5. - shell: docker swarm join-token -q manager
6. register: manager
7. - shell: docker swarm join-token -q worker
8. register: worker
I would run this play once and don't have that logic built yet but I have
not been able to find a method of storing {{ worker }} in a variable so
that I could join the swarm from another host in another play. Any advice?
