Release Schedule

Next Deadline: Feature Blogs, Nov. 2 (Code Freeze, Nov. 16)

Tuesday is the final pre-Code Freeze deadline: it’s time to get your Feature Blog items in. We’re starting the countdown to Code Freeze on the 16th – the Release team has already started semi-weekly burndown meetings.

1.19.16, 1.20.12, 1.21.6, and 1.22.3 are out, including another Golang update.

#105979: De-share the Handler struct in core API

Up until now, we had two systems sharing a configuration struct: probes and lifecycle hooks. This has lead to some confusing mis-features like HTTP calls for lifecycle hooks. These have now been split from a single Handler to ProbeHandler for probes and LifecycleHandler for hooks. In keeping with our compatibility guarantees both new structs are currently identical but it opens the door for future improvements, adding features only where it makes sense. If you’re building a PodSpec in Go code anywhere and it includes probes or hooks, make sure you update your struct names to match the new API.

#99557: ‘kubectl events’ command

While the venerable kubectl get events has long served for basic debugging and shell scripting, there was always a lot of room for improvement. As a new alpha-level command, we have kubectl alpha events to build this future on. The biggest new feature is a --for CLI option which takes an object reference and filters the output. Check out the KEP for ideas on future features which I’m sure SIG-CLI would love help with!

PodSecurity Party

PodSecurity has seen a huge burst of activity, so let’s just go through all of them!
