Hi,
have started evaluating ansible playbook functionality to perform
simple config management tasks.
I have experienced several problems. Tried to get some help on irc,
and through web searches, but.. well. I'm here :)
I'm running the following playbook:
-------8<-------
# test.yml
---
- hosts: all
become: yes
tasks:
- name: Install hoardr-client for RedHat/CentOS
yum: "name={{ item }} state=installed"
with_items:
- hoardr-client
when: ansible_pkg_mgr == 'yum'
- name: Install hoardr-client for Debian/Ubuntu
apt: "name={{ item }} update_cache=yes"
with_items:
- hoardr-client
when: ansible_pkg_mgr == 'apt'
-------8<-------
(more on this playbook later)
What happens is that the "when:" condition seems to fail
miserably (wrapping is likely to destroy this, so
http://pastebin.com/YtcNuxnj holds the original):
-------8<-------
# Running: ansible-playbook test.yml
TASK [Install hoardr-client for RedHat/CentOS]
*********************************
fatal: [localhost.localdomain]: FAILED! => {
"failed": true,
"msg": "The conditional check 'ansible_pkg_mgr == 'yum'' failed.
The error was: error while evaluating conditional
(ansible_pkg_mgr == 'yum'): 'ansible_pkg_mgr' is undefined
The error appears to have been in
'/home/cosimo/src/sys/ansible/test.yml': line 9, column 5, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
- name: Install hoardr-client for RedHat/CentOS
^ here"}
to retry, use: --limit @/home/cosimo/src/sys/ansible/test.retry
-------8<-------
I traced this back to facts gathering not working for some reason.
Next step I tried:
ansible -m setup <hostname> | grep ansible_pkg_mgr
"ansible_pkg_mgr": "apt",
it would seem the answer I got was correct,
so what is going wrong here?
Side notes:
1) searching around, I found instances of the following syntax:
when: "'$ansible_pkg_mgr' == 'yum'"
This is not working either. I hope this is on purpose :-)
2) I found a `package' directive, which I'd really wish I could use,
instead of yum/apt alternate code paths. When I try it,
I get the following error message:
... cannot detect which package manager to use: try gathering facts
or setting the "use" option.
What is the "use" option? I can't seem to find it anywhere.
Thanks for at least reading through this,
