Node reboot in a chef recipe


#1

Hello,

I am looking for strategies on node rebooting within a recipe.

I am aware of dreamcat4’s restart cookbook, but I don’t want to patch chef
in order to make it work.

How do you guys reboot your nodes in a chef run?

Thanks.

execute “reboot”

Is that what your asking: to perform an actual OS/server reboot?

Brian had it pretty much covered. Nothing “special” is required.

If you need a bit more “coordinated” reboot, the Webster-Clay guys
created something called “dominodes” that uses a data bag as a mutex
for coordination:

Nothing special needed,

I have the belief that a server reboot in between a chef-run could be
harmful. I will delay the reboot at the end of the chef run at least.

Thanks for your help.

One elegant way you could solve this is to set a flag in node.run_state (inside of a recipe), then look for this flag in a chef report handler [0].

node.run_state[:reboot] = true

This would ensure the reboot happens only after a successful chef run.

The handler strategy looks nice, I’ll follow that path.

Thanks :slight_smile:
