Handling ec2 terminated hosts

Chef Infra (archive)

Hi

I was wondering if there are best practices for handling terminated
instances on ec2. When an instance dies unexpectedly it’s still registered
with chef server. Currently I’m running a script that lists all registered
instances and all running ec2 instances and compares them. Although it’s
working, I was wondering if there are better ways to handle this.

Thanks in advance

Basically that's what I do. Here's my version. Would love to know if anyone has any improvements:

Very nice, Alex!

I have a very crude blunt instrument that runs "knife {node,client,ec2 server} delete" on an instance ID. I think I like your's for practical use better :-).
