Release Schedule

Next Deadline: Enhancements Freeze June 23rd (PRR June 16th)

The Enhancements Freeze has been pushed back to June 23rd to accommodate the many SIGs with a backlog of KEPs to review. Please get your draft KEPs to Production Readiness by this Thursday (the 16th).

New patch releases for all supported versions are planned for this Wednesday.

enhancements#2813: [Bucket API] KEP updates for API review

The Container Object Storage Interface (COSI) team has merged a PR targeting a revamped COSI API to be alpha in 1.25. COSI is a plugin framework similar to CSI but for object storage systems rather than block storage. The end goal is to provide a basic abstraction layer and self-service toolkit for object storage just as we do for block storage. This includes provisioning and deprovisioning the buckets themselves, a simplified access policy abstraction, and being able to provide a workload with credentials or other access information to use the storage bucket.

enhancements#3179: KEP-3178: Cleaning up IPTables Chain Ownership

Both kube-proxy and kubelet create/manage IPTables firewall rules at various points in the codebase. This KEP aims to clarify and streamline things so we can converge on kube-proxy owning all the rules it needs to operate. This will both improve code clarity and streamline things for users of alternate service proxy implementations.

enhancements#3289: KEP 3288: Split stdout and stderr log stream

A common UNIX convention (at least as applied to containers) is to write basic log data to stdout and errors or other exceptional issues to stderr. While we expose container logs via kubectl logs and the matching APIs, it only returns the combined stream of both types of output. This KEP seeks to add a Stream field to PodLogOptions to allow retrieving just one of the two when desirable.

Other Merges

Also, lots of backports of fixes from the last month.
