SSH to EC2 instance ID
I often find myself looking up EC2 nodes by instance ID so I can grab the external DNS name and SSH in. Fed up with the extra “ec2-describe-instance , copy, paste” layer, I threw together a function (basically a fancy alias) to SSH into an EC2 instance referenced by ID.
Assuming you’re on Mac OS X / Linux, just put this somewhere in ~/.profile, reload your terminal, and you’re good to go. Alternatively, you can use the shell script version.Update (3/5/10): Added region support
