Recording generated template configurations

[Soren Olegnowicz]

Anybody know of a way to deploy a template to multiple servers, but have each configuration simultaneously centralized on another server? I do not want the servers speaking with each other, so synchronize would not really be an option. I would also prefer not to use fetch, as having the different configurations live on the main workstation would become too clunky too quickly.

How about delegate_to?

- hosts: myservers

tasks:

- name: put foo on myservers
template:
src: foo.txt.j2
dest: /etc/foo.txt

- name: put foo for myservers onto centralserver
template:
src: foo.txt.j2
dest: "/srv/myservers/{{ inventory_hostname }}"
delegate_to: centralserver

That seems to work for me; it's not *simultaneous* simultaneous, but it's
in one playbook anyway. :^)

you can do in 1 task: 

- template: ....

  delegate_to: "{{item}}"

  with_items:

     - "{{inventory_hostname}}" # or ansible_host, depends on your inventory

     - central-host

I think your Ansible control host would need to be able to SSH to "the
central server", so if it can't, that might give you an error like this. I
tested it in an environment where my control host can SSH to everything.

If "the central server" *is* the Ansible control host, and isn't allowed
to SSH to itself, then 'delegate_to: localhost' should work and not use
SSH at all.

Thanks for the tip about delegation, donno how I have not used it yet. Do you have to change security settings when you do though? I am getting an SSH unreachable error on just that one delegate task (not the rest of them).

use `localhost` instead of the host name, unless you defined 'localhost' in your inventory it should avoid remote connections and use in the 'local' connection plugin.
