Editing running Pods manifests in Kubernetes

You CANNOT edit specifications of an existing POD other than the below:

spec.containers[*].image
spec.initContainers[*].image
spec.activeDeadlineSeconds
spec.tolerations

To make it possible:

1. Extract pod manifest:

   kubectl get pod webapp -o yaml > my-new-pod.yaml

2. Edit the file my-new-pod.yaml
3. Delete the old pod:

   kubectl delete pod webapp

4. Create new pod from edited manifest:

   kubectl create -f my-new-pod.yaml
