Hi guys,
Struggling with something that I'd really appreciate some help with.
I'm putting together a little role to handle rsnapshot configuration.
At the end of a template, I've got a for loop that's supposed to iterate
over every host in our inventory (encompassed by the group 'servers'), look
up their FQDN, and place their configuration in the file.
To do so, I'm wanting to leverage fact lookup. The idea is that there is
some "dummy" job that runs on 'all' hosts, then the rsnapshot role is
applied to the group 'rsnapshot_servers' using the facts gathered from this
"dummy" job.
I've taken a couple approaches and just cannot seem to get this to work.
Here's the approach I'm taking:
Here's the playbook I'm using:
---
- hosts: servers
tasks: # gather facts
- hosts: rsnapshot_servers
roles:
- rsnapshot
Here's the task this issue concerns:
- name: Deploy rsnapshot configuration
template:
src: rsnapshot.conf.j2
dest: /etc/rsnapshot.conf
owner: root
group: root
mode: 0644
validate: 'rsnapshot -c %s configtest'
And here's the block of Jinja2 in the above template that's supposed to be
populating the file:
{% for host in groups['servers'] %}
backup {{ rsnapshot_remote_user }}@{{ hostvars[host]['ansible_fqdn'] }}:/
some/dir/ {{ host }}/
{% endfor %}
This fails with the following message:
TASK [rsnapshot : Deploy rsnapshot configuration]
******************************
fatal: [my.host]: FAILED! => {"changed": false, "failed": true, "msg":
"AnsibleUndefinedVariable:
'dict object' has no attribute 'ansible_fqdn'"}
If I change the playbook target and the Jinja for loop to just target
'rsnapshot_servers' (where the template task is running), this works with
no problem. This leads me to believe that the facts are not being made
available for this task.
Running the above playbook, I can confirm that 'setup' is run on all
systems in the 'servers' group, so fact gathering should be working with no
issues.
I've tried combinations of setting the playbook scope to 'servers' and
using 'run_once'/'delegate_to'/'delegate_facts' to see if I can get the
task to effectively be looking at all 'servers' systems, but it didn't work.
Does anyone have any idea how I can achieve this?
I need to populate this file with facts about systems from the inventory.
I'll also be introducing some other lookups into the for loop - but I need
to at least tackle this first.
Thanks in advance for any help on this, it's greatly appreciated.
