Kops ripped out Kopeio networking support overnight, and your test infrastructure needs to catch up.

The deprecated Kopeio CNI is officially dead in Kops [1], with maintainers citing the archived kopeio/networking repo during office hours. The merge landed alongside test-infra PRs removing the kopeio jobs [2], so clusters that still use it will break on upgrade. Before you touch anything, note the Akamai (Linode) volume label bug [3] that fails with a 400 on long cluster names; a fix normalizes labels to the API's 1 to 32 character limit. Meanwhile, minikube bumped its ISO kernel from 6.6.95 to 6.6.152 [4], using Buildroot LTS 2025.02.16 and savedefconfig rewrites so the kernel diff is purely a version change. The kops maintainers called Kopeio "deprecated and archived" [1], so migration to another CNI is non-negotiable. Also in test-infra, site-only changes in minikube will skip presubmit jobs [5], unblocking doc typo fixes like the 3-line PR stuck behind flaky tests for days.
