Upgrade node specs for existing Kubernetes cluster

kubernetes vmware

Restart Kubelet does the trick but its not practial in case of larger clusters.

$ kubectl get nodes node-02 -o yaml | grep mem    memory: 16145384Ki    memory: 16247784Ki    message: kubelet has sufficient memory available

After restart:

$ kubectl get nodes node-02 -o yaml | grep mem    memory: 32922600Ki    memory: 33025000Ki    message: kubelet has sufficient memory available
