Known Issues
- There is a regression that may cause issues with deleting nodes due to finalizers not being removed. If you observe a node is stuck for some time and is not being deleted you can describe the node to see if any finalizers remain. If there are any finalizers, you can work around this issue by running the following command to remove the finalizers:
# replace <nodename> with the name of the node
kubectl get node -o name <nodename> | xargs -i kubectl patch {} -p '{"metadata":{"finalizers":[]}}' --type=merge
