Run Command when Kernel RPM Changes

Hello all,

I'm fairly new to puppet and have a quick question. I need to run a command whenever a new kernel is installed via a "yum update" on a CentOS 7 box. In particular I'm using enhanced networking drivers on AWS instances that require an argument be passed to the kernel line in grub, and then the grub.cfg rebuilt.

So, each time the kernel RPM changes, I need to run the command. Is there a simple way (or forge module) to do that?

Thanks, TR

I think Puppet is not the right tool for this particular problem.

If you're using Puppet Enterprise, then this is exactly why Live Management is there. If you're not using Puppet Enterprise, you could look at the open source MCollective. That will be easy enough if you're using Puppet 4 and can benefit from the all-in-one package that contains MCollective.
