Just noticed an issue with ansible 1.4.1 trying to deploy a networking
configuration for dhcp. Will paste configs below with hostnames changed:
*Playbook:*
#playbook.yml
---
- hosts: "{{ dhcp_hosts }}"
user: ansible
sudo: yes
roles:
- /home/ansible/Ansible/roles/dhcp
tasks:
- name: Ensure that dhclient is installed first
yum: name=dhclient
state=present
tags: deploy
- name: Restart the network
service: name=network
state=restarted
tags: network
*DHCP ROLE:*---
#Drop a network config for dhcp
#
#Drop the /etc/sysconfig/network-script/ifcfg-eth0 template
- name: Drop the ifcfg-eth0 script
template: src=/home/ansible/Ansible/templates/dhcp/ifcfg-eth0.j2
dest=/etc/sysconfig/network-scripts/ifcfg-eth0
owner=root
group=root
mode=0644
tags: deploy
- name: Drop the /etc/dhclient-eth0.conf file
copy: src=/home/ansible/Ansible/files/dhcp/dhclient-eth0.conf
dest=/etc/dhclient-eth0.conf
owner=root
group=root
mode=0644
tags: deploy
When the above playbook and role are run without --check (even with
--diff), it functions as expected. The appropriate template is dropped as
ifcfg-eth0. Where it gets interesting is if you run the same code with
"--check --diff":
TASK: [/home/ansible/Ansible/roles/dhcp | Drop the ifcfg-eth0 script]
*********
--- before: /etc/sysconfig/network-scripts/ifcfg-eth0
+++ after: /home/ansible/Ansible/templates/dhcp/ifcfg-eth0.j2

DEVICE=eth0

+DHCP_HOSTNAME=*###REMOVED###*

It seems as though ansible implementation has the "src" and "dst" flags
switched, only when run with a "--diff --check". Has anyone else seen this
behavior? The --check and --diff are vital components of our testing to
make sure we don't deploy incorrect configs to our production servers.
Also, I have ensured that there is not a .j2 file present on any target
servers and have tested across 10 different servers.
Thanks,
Matt
