Answer 1

It looks to me that you are using a Deployment API Object. Therefore, if you remove the pod it will be recreated. Try the following:

kubectl  get deployments

Get the deployment id and execute

kubectl delete deployment DEP_ID

Then it will be removed. If there is no deployment check replicasets as well

Answer 2

Try restarting the docker daemon on the master node
