Having monit complement ansible

2013/09/14

Here is a weird thing:

When running /etc/init.d/milter-greylist restart via ansible (either direct or via a playbook) it hangs. I had no time to debug this, so I reverted to the next best workaround since the machine was already running monit:

Have ansible distribute greylist.conf and then have monit restart the process. So here is a simple playbook:

- hosts: greylist
  user: root
  tasks:
  - name: copy local milter-greylist configuration to hosts
    action: copy src=/usr/local/etc/greylist.conf dest=/etc/milter-greylist/greylist.conf

and here is how monit finishes the task:

check file greylist.conf with path /etc/milter-greylist/greylist.conf
 if changed checksum then exec "/etc/init.d/milter-greylist restart"

Of course this is just a simple case of having the two cooperate. But once you get the hang of it, more elaborate schemes where ansible and monit can cooperate will pop out.
