Exploring etcd snapshots with koff

We have looked at etcd performance and how critical it is to cluster health, but what if we want to see what’s in etcd?

If you have existing etcd backups / snapshots or want to take one now, there is a lot you can do and look at!

If you deleted someone important and want to get it back, you can get it from a backup and recreate it in your cluster.

If your etcd database is huge, you can parse through a fresh snapshot and see where the issues are without touching production.

Accessing and parsing your etcd data isn’t a daily occurance, but when the time comes, it’s incredibly useful.

In this module we will utilize the koff tool to showcase get and inspect commnads on both standard Kubernetes objects types as well as traditionally stored etcd keys.
