Almost-Annual Upgrades

Every 10 months I run upgrades on my Kubernetes cluster. I haven’t blogged about my cluster setup or hardware before; I set it all up pretty shortly after I wrapped up my home lab blog posts, part 5. Maybe in the future I’ll document my initial setup, but that’s out of scope for this post.

In this upgrade I needed to upgrade from 1.33 all the way to 1.36 - hitting 1.34 and 1.35 along the way. So I read through the upgrade documentation for 1.34 to 1.36… 1.34 itself was no concern, and neither was 1.36. But 1.35? It deprecated support for containerd versions less than 2.0. And I was running 1.7 at the time.
