Worker nodes upgraded to latest k8s version and I am facing the 'NotReady' status of those worker nodes. I see 'PIDPressure - False' when I do a 'kubectl describe' for these nodes.
Deleting the stale Docker containers on the K8s nodes and restarting the services has resolved my issue. Upgrading to latest K8s is not necessary.
PIDPressure - False
^^ is an expected condition of the healthy node, it means that kubelet has sufficient PIDs available for normal operation.
Need more details:
kubectl version
kubectl describe node <node-name>
sudo journalctl -u kubelet --all|tail
