Kubernetes pod gets recreated when deleted

Question

I have started pods with command

$ kubectl run busybox --image=busybox --restart=Never --tty -i --generator=run-pod/v1

Something went wrong

Answer 1

You can do kubectl get replicasets check for old deployment based on age or time

Delete old deployment based on time if you want to delete same current running pod of application

kubectl delete replicasets <Name of replicaset>

Answer 2

I also faced the issue, I have used below command to delete deployment.

kubectl delete deployments DEPLOYMENT_NAME

but still pods was recreating, So I crossed check the Replica Set by using below command

kubectl get rs

then edit the replicaset to 1 to 0

kubectl edit rs REPICASET_NAME

Answer 3

In some cases the pods will still not go away even when deleting the deployment. In that case to force delete them you can run the below command.

kubectl delete pods podname --grace-period=0 --force

Answer 4

After taking an interactive tutorial I ended up with a bunch of pods, services, deployments:

me@pooh ~ > kubectl get pods,services
NAME                                       READY   STATUS    RESTARTS   AGE
pod/kubernetes-bootcamp-5c69669756-lzft5   1/1     Running   0          43s
pod/kubernetes-bootcamp-5c69669756-n947m   1/1     Running   0          43s
pod/kubernetes-bootcamp-5c69669756-s2jhl   1/1     Running   0          43s
pod/kubernetes-bootcamp-5c69669756-v8vd4   1/1     Running   0          43s

NAME                 TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
service/kubernetes   ClusterIP   10.96.0.1    <none>        443/TCP   37s
me@pooh ~ > kubectl get deployments --all-namespaces
NAMESPACE     NAME                  DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE
default       kubernetes-bootcamp   4         4         4            4           1h
docker        compose               1         1         1            1           1d
docker        compose-api           1         1         1            1           1d
kube-system   kube-dns              1         1         1            1           1d

To clean up everything, delete --all worked fine:

me@pooh ~ > kubectl delete pods,services,deployments --all
pod "kubernetes-bootcamp-5c69669756-lzft5" deleted
pod "kubernetes-bootcamp-5c69669756-n947m" deleted
pod "kubernetes-bootcamp-5c69669756-s2jhl" deleted
pod "kubernetes-bootcamp-5c69669756-v8vd4" deleted
service "kubernetes" deleted
deployment.extensions "kubernetes-bootcamp" deleted

That left me with (what I think is) an empty Kubernetes cluster:

me@pooh ~ > kubectl get pods,services,deployments
NAME                 TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
service/kubernetes   ClusterIP   10.96.0.1    <none>        443/TCP   8m

Answer 5

In my case I deployed via a YAML file like kubectl apply -f deployment.yaml and the solution appears to be to delete via kubectl delete -f deployment.yaml

Answer 6

You need to delete the deployment, which should in turn delete the pods and the replica sets https://github.com/kubernetes/kubernetes/issues/24137

To list all deployments:

kubectl get deployments --all-namespaces

Then to delete the deployment:

kubectl delete -n NAMESPACE deployment DEPLOYMENT

Where NAMESPACE is the namespace it's in, and DEPLOYMENT is the name of the deployment.

In some cases it could also be running due to a job or daemonset. Check the following and run their appropriate delete command.

kubectl get jobs

kubectl get daemonsets.app --all-namespaces

kubectl get daemonsets.extensions --all-namespaces
