Week Ending April 19, 2020

Developer News

SIG-PM (Project Management) is gone now, mostly because the chairs decided that the SIG was redundant with other SIGs, mostly SIG-Arch, but also SIG-Contribex and SIG-Usability. As part of this, SIG-PM’s subprojects, such as Enhancements, have been moved.

Timothy St. Clair has stepped down from the Steering Committee to avoid having too many VMware folks on it.

In last week’s monthly community meeting, we heard from SIG-Docs (who are moving to the Hugo Docsy theme), SIG-CLI (kubectl moving out of core), and SIG-Node (topology management and RuntimeClass). Kubernetes will be participating in the CommunityBridge Mentorships this term.

Release Schedule

Next Deadline: Enhancements Freeze, May 5

We are well into 1.19 now, so get your KEPs and feature proposals ready for what you’re working on this term.

Last week we released updates to all supported branches: 1.16.9, 1.17.5, and 1.18.2. This update fixes a client-go regression, and requires a golang version update for 1.16 and 1.17.

Featured PRs

#90252: Separate go module for tools to avoid polluting root go.mod

Coming into 1.19 development strong with a big cleanup of developer-only dependencies. These have now been split off into their own file to both reduce repo footprint and reduce downstream dependency complexity.

#90010: generate metadata for requiring transition from beta

Along with #90247, this adds annotation-driven codegen for tracking the lifecycle of types. The new annotations look like:

// +k8s:prerelease-lifecycle-gen:introduced=1.1
// +k8s:prerelease-lifecycle-gen:deprecated=1.8
// +k8s:prerelease-lifecycle-gen:removed=1.18
// +k8s:prerelease-lifecycle-gen:replacement=apps,v1,Deployment

and create a zz_generated.prerelease-lifecycle.go full of useful information. If you work on any developer tooling which cares about deprecations, check this out.
