Kubernetes Operations removes gossip DNS support entirely in 1.37, completing a deprecation cycle that eliminates protokube and its mesh dependencies.

kOps shipped the final gossip removal with documentation and migration guidance [1][2][3]. The cleanup deletes the protokube binary [4], removes the forked memberlist library, and purges unused gossip dependencies [5], marking the end of a decade-old DNS discovery mechanism. Meanwhile, Kubernetes core pinned github.com/google/cel-go to v0.29.2 after v0.30.0 broke unit tests [6], and upgraded the default COS image to cos-129-lts shipping containerd v2.2.5 for proper CRI metrics support [7][8]. The test infrastructure refreshed CAPA job configs to add release-2.13 jobs while dropping 2.9 and 2.10 [9][10], and patched kOps AMI selection to filter by region availability [11]. Cloud provider AWS narrowed security group cleanup logic to prevent unintended revokes of consolidated rule pairs [12][13], while documentation work continued across localization [14][15] and a controller-runtime blog post received a caution banner for technical accuracy [16].

Action items

→ Plan kOps gossip migration before 1.37 upgrade using provided step-by-step guide kubernetes/kops [plan]
→ Verify CEL-go pinning does not block your dependency updates kubernetes/kubernetes [monitor]
→ Review AWS security group cleanup changes if using CLB with bring-your-own security groups kubernetes/cloud-provider-aws [monitor]
