Answer 1

If you created the pod using kubectl run, then you will need to delete the deployment (which created the replica set, which created the pod). Otherwise, the higher level controllers will continue to ensure that the objects they are responsible for keeping running stay around in the system, even if you try to delete them manually. Try kubectl get deployment --namespace=kube-system to see if you have a deployment in the kube-system namespace. If so, deleting it should also delete the replica set and the pods that you created.

Answer 2

If a pod is recreated even after kubectl delete pod-name, it means that the pod is controlled by a higher level kubernetes objects such as Deployment, Replicaset, Replication controller.

You can use kubectl describe pods pod-name | grep Controllers to find which controller your pod belongs to. You need to delete this higher level object to delete the pod.
