Featured PRs
133604: Fix storage counting all objects instead of objects for resource
This PR fixes a regression where apiserver_storage_objects was overcounted by counting all etcd objects (using /registry) instead of just the target resource (e.g., pods); It now counts only that resource’s objects, thus giving accurate per-resource metrics and avoiding extra work when the watch cache is disabled.
KEP of the Week
This KEP introduces support for AppArmor within a cluster. AppArmor can enable users to run a more secure deployment, and/or provide better auditing and monitoring of their systems. The AppArmor support provides users an alternative to SELinux, and provides an interface for users that are already maintaining a set of AppArmor profiles. This KEP is proposing a minimal path to GA, per the no perma-Beta requirement.
This KEP was released as Stable in 1.34
Other Merges
- Count storage types accurately when filtering per type
- Prevent data race around claimsToAllocate
Subprojects and Dependency Updates
- cluster-api v1.11.0 adds support for Kubernetes v1.33 (management and workload clusters), introduces the v1beta2 API, and includes new providers (Scaleway, cdk8s)
- kubespray v2.28.1 fixes etcd and kubeadm issues while improving Cilium, Hubble, and Calico networking stability
Shoutouts
- Christian Schlotter (@chrischdi): Thanks to Fabrizio Pandini (@fabrizio.pandini) and Stefan Büringer (@sbueringer) for the huge amount of work they did for the latest cluster api :cluster-api: v1.11.0 release to set the stage for the v1beta2 api version, which benefits all users to have a more clear and consistent API as well as a better feedback loop!
