I don't like to upgrade things that are working. Unfortunately that bit me in the butt with Kubernetes. Long story short, a node crashed, and when it came back up, the pods wouldn't start. We spent a couple days trying to figure it out, but nothing was working. This was in production, so we made the choice to rebuild the entire cluster again with a newer version. We still had other nodes running, and were scaled enough that there was no complete downtime, but we were maxxing the cpu and some connections were getting dropped.
