using gathered fact in another play in the same playbook

Hi all!

Let’s say I have a few hosts (a.local, b.local) with postgresql installed, and I want to add them to bacula system on a backup host (backup.local).
Basically, each database host would have have a file named {{ hostname }}.conf with the following:

  1. Extra vars are totally available between plays.

  2. Yes, you can get to variables registered for other systems through hostvars:

{{ hostvars[your_hostname_here][variable_here] }}

Thanks! #2 is what I wanted!

I’ve written a small discovery script:

`
#!/bin/sh

for path in “$@”
do
if [ -d “$path” ] || [ -f “$path” ]
then
echo -n “$path”
exit 0
fi
done
exit 1
`

And use it:

`

  • hosts: {{ hostname }}
    tasks:

  • name: discover
    script: “discover.sh ‘/tmp’ ‘/etc’”
    register: pgdir

  • hosts: bacula.local
    tasks:

  • debug: msg=“{{ hostvars[hostname][‘pgdir’][‘stdout’] }}”

`

But can I use extra var “hostname” and NOT add it to /etc/ansible/hosts ?

p.s. there probably should be a module to discover remote paths, how do you think?
