Good morning, this is Kubernetes for September 27th, 2026.
The lead insight is that setting termination grace period to zero does not mean immediate kill, and four related pull requests finally align docs, warnings, and tests with what the kubelet actually does.
First theme is the zero grace cleanup. In pull request 142446, the docs fix notes the API claims zero stops a pod immediately with no chance to shut down, while the kubelet always enforces a minimum of one to two seconds. Pull request 142444 adds an API warning when that field is set to zero, because a delete…
Second theme is small correctness fixes with outsized reliability impact. Pull request 142441 extends crash loop back off to pre-start failures, such as container creation rejections for resource limits below the runtime floor. Previously the kubelet skipped backoff without an exited status and retried every sync…
Finally, maintenance and supply chain. Updates to Gomega, go-openapi pointer libraries with panic guards, and the CoreDNS parser land alongside a cleanup dropping the test library from the CRI API module and moving signal handling into a standard library only package. Merged pull request 142037 adds ML-DSA…
