Manually Edit AWS Console "Switch Role" Configuration in Bash

Motivation

At Gruntwork, we work with multiple software teams. That means we have to modify the "Switch Role" history multiple times. But the only way to do that today is to delete your cookie and clear all AWS Console saved settings. That got old after a while, so these instructions enable you to modify the "Switch Roles" configuration directly.

The Big Picture

Consul: 0.7.2

You may have crashed your cluster so that all Consul servers have been offline at some point. You may be running on Kubernetes. The default 96 hours didn't pass, so there was no reaping of Consul servers. Restarting it all doesn't work. You've read this issue five times over and nothing works. On top of it all, which makes it harder, you're running a StatefulSet on Kubernetes, so you need to do kubectl delete pods/consul-1 to make the container arguments (kubectl replace consul/consul.yml) bite. On top of this, if you kubectl exec -it consul-1 and then kill -9 5, Kubernetes goes into a crash loop with exponential backoff, eating into your time.

Sounds like a Friday pleasure, right?

The tools you have at your disposal are:

-bootstrap
kubectl replace consul/consul.yml
