Having issues using a variable in a playbook

[Benjamin Arntzen]

Hi there,

I'm trying to build python 3.4.2 in a semi-idempotent way. I see mpdehaan's comments on it and didn't have any issues following those.

The issue I'm having is that the variables defined in common.yml aren't being carried through to the second play (python-app-server). I would like to simply define vars_files in the first play and have it carry forward. Am I just thinking about it wrong?

Here's my playbook's site.yml file, as I would like it to look:

---
# file: site.yml
- hosts: all
  user: '{{ deploy_user }}'
  sudo: yes
  vars_files:
    - vars/common.yml
    - [ "vars/{{ ansible_os_family }}.yml", "vars/os_defaults.yml" ]


  roles:
    - base
    - redacted-base


- hosts: python-app-server
  user: '{{ deploy_user }}'
  roles:
    - python-app-server

And here's how it has to look in order to work at the moment:

---
# file: site.yml
- hosts: all
  user: '{{ deploy_user }}'
  sudo: yes
  vars_files:
    - vars/common.yml
    - [ "vars/{{ ansible_os_family }}.yml", "vars/os_defaults.yml" ]


  roles:
    - base
    - redacted-base


- hosts: python-app-server
  user: '{{ deploy_user }}'
  vars_files:
    - vars/common.yml
  roles:
    - python-app-server

I'm totally unconcerned about adding two lines, I just want a much cleaner way to express this. Thoughts?

Thanks,
~ B

Hi Benjamin

Look at specifying variables using group_vars or host_vars (see http://docs.ansible.com/intro_inventory.html#splitting-out-host-and-group-specific-data)

There is a special group 'all' of which all hosts are automatically a member.

Regards

Tom

vars/vars_files/registered vars are in the single play scope, if you
want common.yml vars present in other plays you need to import it
there also.
