Keel rolled csi-driver-nfs 4.13.1→4.13.2 today. The 4.13.2 chart dropped control-plane exclusion from the controller Deployment, so both replicas landed on k8s-master, fought for hostNetwork ports 19809/29653, and one went CrashLoopBackOff. Helm rollback left orphan containerd sandboxes holding the ports — only a kubelet restart on master cleared them. - Pin helm_release.version = "4.13.1" so terraform apply can't drift to the broken chart (defense in depth; nfs-csi namespace is already in the Kyverno-Keel exclude list) - Add controller.affinity: podAntiAffinity between replicas + nodeAffinity excluding node-role.kubernetes.io/control-plane - docs/post-mortems/2026-05-17-nfs-csi-keel-upgrade-master-port-conflict.md captures the root cause + recovery procedure (kubelet restart via nsenter is the escalation path when crictl rmp -f fails) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |
