How do I undo a kubectl create deploy?

Question

I was setting up a nginx cluster on google cloud, and I entered a wrong image name; instead of entering:

kubectl create deploy nginx --image=nginx:1.17.10

I entered:

kubectl create deploy nginx --image=1.17.10

and eventually after running kubectl get pods, It showed ImagePullBackOff as the status for the pod.

When I tried running the correct create deploy command above, It said "nginx" already exists.

When I tried doing kubernetes delete --all pods, the pod was recreated with a new ID but still had the same status, and still couldn't allow me to run the right 'kubectl create deploy' command above. Now I'm stuck.

How can I undo it?

You need to delete the deployment:

kubectl delete deploy nginx

Otherwise Kubernetes will recreate the pod on every shutdown.

You can see all your deployments with

kubectl get deploy
