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

&nbsp;&nbsp;&nbsp;&nbsp;- yum:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;...  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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.

&nbsp;&nbsp;&nbsp;&nbsp;- yum:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;...  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;register: yum\_result

&nbsp;&nbsp;&nbsp;&nbsp;- command: shutdown -r  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;when: \<condition based on yum\_result\>

Note: See details in  
How to access information in ansible yum list result?

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.
