Hi,
I've been trying to get Ansible Tower to run a playbook/role which should
update the /etc/hosts file across all hosts in a group.
I have the following playbook:
- name: Update hosts file if required
hosts: all
gather_facts: yes
roles:
- { role: hostfile }
and the following role:
---
- debug: var=ansible_default_ipv4.address
- name: node to ip mapping
debug: var=hostvars[item].ansible_default_ipv4.address
with_items: groups['all']
- name: Build Host file
lineinfile: dest=/etc/hosts
regex='.*{{ item }}$ }}'
line="{{ hostvars[item].ansible_default_ipv4.address }}
{{item}}"
state=present
when: hostvars[item].ansible_default_ipv4.address is defined
with_items: groups['all']
become: true
However, when Tower run this its skips the 2 hosts in the group. From
looking at the debug output it would appear that Tower is not caching the
facts under hostvars as you can see from the output below:
TASK [setup]
******************************************************************* ok:
[172.31.9.43] ok: [52.50.60.2] TASK [hostfile : debug]
******************************************************** ok: [172.31.9.43]
=> { "ansible_default_ipv4.address": "172.31.9.43" } ok: [52.50.60.2] => {
"ansible_default_ipv4.address": "172.31.33.206" } TASK [hostfile : node to
ip mapping] ******************************************* ok: [172.31.9.43]
=> (item=groups['all']) => { "hostvars[item].ansible_default_ipv4.address":
"VARIABLE IS NOT DEFINED!", "item": "groups['all']" } ok: [52.50.60.2] =>
(item=groups['all']) => { "hostvars[item].ansible_default_ipv4.address":
"VARIABLE IS NOT DEFINED!", "item": "groups['all']" } TASK [hostfile :
Build Host file] ********************************************** skipping:
[172.31.9.43] => (item=groups['all']) skipping: [52.50.60.2] =>
(item=groups['all']) PLAY RECAP
*********************************************************************
172.31.9.43 : ok=3 changed=0 unreachable=0 failed=0 52.50.60.2 : ok=3 changed=0
unreachable=0 failed=0
I have a feeling that I'm missing something very obvious here. Any ideas
where I should look?
Thanks,
Jon
