When yum succeeds, boot?

[Mike Eggleston]

I am working on a playbook that uses yum. When yum does an update of all installed packages I want to do a conditional shutdown -r. What condition do I check from the yum task succeeding?

1) If you want to reboot on any change just notify a handler

- yum:
...
notify: reboot

Note: "update_cache" makes "yum" report "changed" even when no package have
been changed (installed/upgraded/downgraded); hence "update_cache" in a
separate task.

2) If you want to reboot on a particular combination of changes register
"yum_result" and make your choice.

- yum:
...
register: yum_result

- command: shutdown -r
when: <condition based on yum_result>

Note: See details in

Not all package updates require a reboot. 

You can make this more robust by installing yum-utils, run /sbin/needs-restarting, and decide based on what that returns.

Example:

On Debian based distros you’d check for the presence of /var/run/reboot-required.
