KOPS BREAKS ETCD COUPLING, KUBERNETES DROPS DEPRECATED SETS

By RepoJournal · Filed · About Kubernetes

Kops decouples APIServer from local Etcd with load balancer support [ref:1], while core Kubernetes scrubs deprecated libraries ahead of the 1.36 release.

Kops shipped a significant infrastructure shift by adding support for external Etcd on GCP through load balancers [1], eliminating the requirement that Etcd live on control plane nodes. This is the first major move toward more flexible cluster topologies. The same release added Linode SSH key management [2], expanding Kops' cloud provider coverage. On the Kubernetes core side, the project is systematizing code cleanup: deprecated sets.NewString calls are being replaced with generic implementations [3], and test utilities are being reorganized under scheduler ownership [4]. Kube-state-metrics had to implement two new cache.Store interface methods (Bookmark and LastStoreSyncResourceVersion) to stay compatible with client-go 0.36.2 [6], signaling that the metrics tooling ecosystem is keeping pace with core API changes. Test infrastructure pruned four permanently failing kops upgrade jobs that were incompatible with kops 1.36.0-beta.1 [5], cleaning up CI noise before the release stabilizes.
