template: shows change every time but no change?

The tasks

      dest="/etc/sysconfig/network/ifcfg-{{ item.device }}"

  with_items:

The network_interfaces variable

network_interfaces:

    - device: "eth1"

      name: "domain1.com"

      bootproto: "static"

      address: "192.168.100.1"

      netmask: "255.255.255.0"

      gateway: "192.168.100.254"

    - device: "eth2"

      name: "domain2.com"

      bootproto: "static"

      address: "172.18.28.201"

      netmask: "255.255.0.0"

The template file (ifcfg.j2)

STARTMODE='auto'

USERCONTROL='no'

BOOTPROTO='{{ item.bootproto }}'

IPADDR='{{ item.address }}'

NETMASK='{{ item.netmask }}'

{% if item.broadcast is defined %}

BROADCAST='{{ item.broadcast }}'

{% endif %}

{% if item.ethool_options is defined %}

ETHTOOL_OPTIONS=''

{% endif %}

{% if item.mtu is defined %}

MTU=''

{% endif %}

{% if item.name is defined %}

NAME='{{ item.name }}'

{% endif %}

{% if item.network is defined %}

NETWORK=''

{% endif %}

{% if item.remote_ipaddr is defined %}

REMOTE_IPADDR=''

{% endif %}

Every run of Ansible says eth1 and eth2 have changed.

I copied the ifcfg-eth1 to ifcfg-eth1.bak and ran Ansible again. The diff of the files shows nothing different. 

What determines if the file needs to be "changed"?

Have you tried running Ansible with --diff to see what it says is changing?

Thank you for the advise. 

It looks like it's not an Ansible thing. It looks like only happens when I run the Ansible playbook via Vagrant.

Thanks again.
