Dr etcd; or; How I Learned to Stop Worrying and Love the Datastore - Nick Young, VMware

Sign up or log in to save this to your schedule and see who's attending!

If you’ve deployed your own Kubernetes cluster, care and feeding of an etcd cluster is a necessary evil. At the end of the day, etcd is the place where your cluster’s buck stops, and despite the marketing hype, operating an etcd cluster at scale is not a set and forget experience.

This talk tells a story of how my team grew from etcd novices to delivering a well-monitored, reasonably resilient, etcd system that could be upgraded in less than half an hour per cluster, online, with no downtime.

After this talk, you will have:
- a better understanding of etcd's sharp edges, and what you can do to avoid catching yourself on them
- some insights on key etcd metrics to keep an eye on and why
- what we tried with upgrades, what worked, and what didn't, and how you can avoid stepping in our potholes
- some war stories, like when we accidentally made 80k namespaces in Kube and filled our etcd.
