You need to upgrade your Kubernetes clusters to pick up security patches and new features. Are you intimidated? What could go wrong? There are many pitfalls, including but not limited to: API deprecation, mismatching addon versions, deprecated control-plane extensions, incorrect upgrade order, and upgrades in HA setup, etc. The other side of the coin is also worth exploring, if an upgrade goes wrong, how to safely downgrade. This talk gives you a deep dive on the pitfalls, suggests rule-of-thumb, and reviews community efforts on safer upgrades. Attendees will walk away with more confidence in upgrading their Kubernetes clusters.
