Debugging etcd - Joe Betz & Jingyi Hu, Google
Oh no, something’s wrong with my Kubernetes cluster! Was it something I did? Or maybe one of those controllers we installed? The answers might be hidden in the etcd’s logs or data files. We’ll walk through real-world examples of how to make sense of etcd logs and correlate issues back to the commands or controllers that initiated them. We’ll cover tools we use to get answers from etcd’s data files, what to look for, and how to quickly get a cluster healthy again.
