Busybox - How to delete looping creations of busybox containers

I created a namespace inside Kubernetes and tried to create a container using the following command:

kubectl run busybox -it ----image=busybox -- sh

But now, everytime I delete the pod using kubectl delete pods --all, it deletes the pod that was just created and it automatically recreates a new pod. I looked through the documentation but am unable to figure out what flag will stop this incessant creation of these containers.

The reason it does this is because kubectl run implicitly creates a deployment for the pod. Deployments are tasked with ensuring a certain number of pods are always running, so when Kubernetes detects a misalignment in the number of pods the deployment should be running vs the number that are actually running, it'll spin up a new one. You can remedy this by deleting the deployment: kubectl delete deployment busybox

Alternatively, you can temporarily kill the pods (but keep the deployment) by scaling down the deployment to run 0 pods: kubectl scale deployment busybox --replicas=0.

Documentation: https://kubernetes-v1-4.github.io/docs/user-guide/kubectl/kubectl_run/

Create and run a particular image, possibly replicated. Creates a deployment or job to manage the created container(s).
