Dalton Hubble 1786e34f33 Revert Graceful Node Shutdown feature ... * Disable Kubelet Graceful Node Shutdown on worker nodes (enabled in Kubernetes v1.25.0 https://github.com/poseidon/typhoon/pull/1222) * Graceful node shutdown shutdown allows 30s for critical pods to shutdown and 15s for regular pods to shutdown before releasing the inhibitor lock to allow the host to shutdown * Unfortunately, both pods and the node are shutdown at the same time at the end of the 45s period without further configuration options. As a result, regular pods and the node are shutdown at the same time. In practice, enabling this feature leaves Error or Completed pods in kube-apiserver state until manually cleaned up. This feature is not ready for general use * Fix issue where Error/Completed pods are accumulating whenever any node restarts (or auto-updates), visible in kubectl get pods * This issue wasn't apparent in initial testing and seems to only affect non-critical pods (due to critical pods being killed earlier) But its very apparent on our real clusters Rel: https://github.com/kubernetes/kubernetes/issues/110755		2022-09-10 14:58:44 -07:00
