Hi,
I had a playbook that I *think* used to work, but I'm finding now that
variables other than the ones I intended are being applied to a particular
host. Does the following minimal test case look sane?
I have vars file at roles/mariadb/vars/credentials.yml with some default
settings:
---
mysql_root_passphrase: foo
I have a more specific vars file at
roles/mariadb/vars/credentials-rails-sandbox.yml ("rails-sandbox" is the
hostname in my inventory) with some overrides:
---
mysql_root_passphrase: bar
My inventory, defined in a file called staging, looks like this:
[general]
general-sandbox
[rails]
rails-sandbox
And my playbook, rails.yml, looks like this:
- hosts: rails
roles:
- { role: mariadb }
vars_files:
- [ "roles/mariadb/vars/credentials-{{ inventory_hostname }}.yml",
roles/mariadb/vars/credentials.yml" ]
I apply it with this:
ansible-playbook -i staging rails.yml
But when I come to run the tasks in roles/mariadb/tasks/main.yml, this one
ends up using the variables from credentials.yml instead of
credentials-rails-sandbox.yml:
- name: mariadb | set up root user credentials
template:
src=dot-my.cnf.j2
dest={{ item.directory }}/.my.cnf
owner={{ item.username }}
group={{ item.username }}
mode=600
with_items:
- username: root
passphrase: '{{ mysql_root_passphrase }}'
directory: /root
sudo: yes
I used the debug module to print the inventory_hostname, and it is
rails-sandbox like I expect:
- name: mariadb | debug inventory_hostname
debug: msg="inventory_hostname is {{ inventory_hostname }}"
During the run I also see that the credentials-rails-sandbox.yml file is
being read:
GATHERING FACTS
***************************************************************
ok: [rails-sandbox]
rails-sandbox: importing
/Users/glh/code/ansible-configs/roles/mariadb/vars/credentials-rails-sandbox.yml
But when the task runs the wrong password is used:
TASK: [mariadb | mariadb | set up root user credentials]
**********************
ok: [rails-sandbox] => (item={'username': 'root', 'directory': '/root',
'passphrase': u'foo'})
The docs <http://docs.ansible.com/playbooks_variables.html> make me think
that the values from my more specific vars file should be taking
precedence, but they're not.
Am I misunderstanding the way variable precedence works in Ansible? Any
obvious mistakes in here?
Thanks for your help.
