I want to remove zk and kafka from my k8s
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
kafka1-mvzch 1/1 Running 1 25s
kafka2-m292k 0/1 CrashLoopBackOff 8 20m
zookeeper1-qhmnf 1/1 Running 0 20m
zookeeper2-t7r8w 1/1 Running 0 20m
$kubectl delete pod kafka1-mvzch kafka2-m292k zookeeper1-qhmnf zookeeper2-t7r8w
pod "kafka1-mvzch" deleted
pod "kafka1-m292k" deleted
pod "zookeeper1-qhmnf" deleted
pod "zookeeper2-t7r8w" deletedbut when I run get pods, it still shows the pods.
And I got no service and deployment
$ kubectl get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes ClusterIP 10.100.0.1 <none> 443/TCP 7h1m
$ kubectl get deployment
No resources found in default namespace.You can use kubectl get pod -ojsonpath='{.metadata.ownerReferences}' to identify the owner object of the pods. The owner might be a Deployment, StatefulSet, etc.
Looking at the medium.com guide that you mentioned, I see that they suggest to create ReplicationControllers.
You can cleanup your namespace by running kubectl delete replicationcontroller --all.
You are removing the pods, and they will be deleted. But there is some other construct that re-creates pods to replace the (now deleted) previous pods.
In fact, the names of the pods with the random-looking suffix suggest that there is another controller operating the pods.
When looking at the linked tutorial, you notice that a ReplicationController is created. This ensures the pods.
If you want to remove it, remove the replication controller; the pods will be deleted as well.
