Next Deadline: Enhancements Freeze, Sept. 9th
Enhancements Freeze is just around the corner! Make sure you’ve got everything sorted out on the Enhancements Sheet.
Featured PRs
#103631: Automate code generated by using mockgen and go:generate
Our mockgen usage has been moved from “remember to run this” comments into go:generate. Together with a new hack/update-mocks.sh script to run go generate for any changed files, this streamlines and automates the management of these mock interfaces. If you’re editing anything with a mockgen generate comment, make sure you run the update script before committing.
#104590: Add GA AnnStorageProvisioner annotation to PVC
The volume.beta.kubernetes.io/storage-provisioner annotation used for communication between Kubernetes and CSI now has a GA version: volume.kubernetes.io/storage-provisioner. The old annotation is still present but deprecated. Any tooling relying on it should update to check for the new key first.
Merges
- Controller-manager has a more flexible health check system
- PodSecurity will run before PodSecurityPolicy so that audit and warn rules in PodSecurity can still trigger
- Reduce parallel type checks to 2 threads to reduce RAM usage
- Kubelet resource calculations will not include completed pods
Deprecations
volume.beta.kubernetes.io/storage-provisionerannotation is deprecated, see above
Removals
--seccomp-profile-rootKubelet config removed in favor of using the<root-dir>/seccompdirectory
Version Updates
- Test images now include Windows ltsc2022
