Learning about the history of CEL in Kubernetes. Did you know it was first introduced 10 releases ago!? 🤯 We are fans of CEL in Kubernetes mainly thanks to them making Validating and MutatingAdmissionPolicies possible to avoid those risky webhooks in our clusters! #KubeCon #MaintainersSummit

Kubernetes apparently made it into an NCIS episode - DURING KubeCon. I guess theres any clear indicator that K8s has hit peek adoption, its that it gets used as techno-jargon to explain things in TV 🤣 Thanks @thisisnotapril.bsky.social for the find. youtu.be/AzrHurE_PSI

If you could make everyone understand one truth, what would it be? I'll go first: Very few things in life are zero sum. We are all better off if we find ways for everyone to win instead of thinking that for us to win someone has to lose.

As you may know Kubernetes API as a suite of tests for conformance to ensure that the developer experience is consistent across Kubernetes distributions. For the longest time we had tech debt in the sense that we did not cover the entire API fully. We have been tracking this for a while!

Quite a lot of discussion around @bsky.app here at #KubeCon, and consensus that it was @kelseyhightower.com 's clear exit from the other place that was the tipping point for the cloud native community coming over here en masse. Thank you Kelsey for your leadership in this and so many other ways.
