Find a list of aws instances based on their tag "Name"

Access aws instances easily even after dns name changes

Restarts of aws ec2 instances can cause ips and dns names to change if you don't pay for static IPs

This set of scripts enables quick ssh access to a group of similarly named machines

  1. run generate-instance-list.sh to get a list of aws instance ids
  2. run ssh-connect.sh against the generated list to access any of the instances

TODO

Currently it is not possible to differentiate the machines easily - enable access by more human readable names in the generated instance list.
