Send a message prior to reboot?

[jmreicha]

Was curious if there was a way to tell the operator to send a message/alert when nodes get scheduled to reboot? I poked through the code a little bit but didn't see a way.

Also, is this project being actively maintained these days or is it mostly in maintenance mode?

You could use the before and after reboot annotations to run a custom pod. That could let you send a message in some way you prefer (email, slack) without CLUO implementing it directly.
