kubernetes -I changed the deployment name ,then redeploying to the environment,how to cleanup the old deployment and pods with old name?

Question

Had requirement to change the pod or deployment name.now when we deploy,we have 2 deployments and 3 pods each with old and new name So far i was deleting the old deployments manually.

do i need to manually delete the old deployment and pods or is there a better method?

Yeah, you need to delete the previous one manually. Object names in Kubernetes are immutable, so you can't rename them. — Kamol Hasan, Apr 29 '20 at 09:03
Why don't you just keep the same name and apply the changes to the existing deployment? `$ kubectl apply -f deployment.yaml` — Kamol Hasan, Apr 29 '20 at 09:05
just delete old deployment by its name. It will delete underneath old pods. kubectl delete deploy old-deploy-name. — Janitha Madushan, Apr 29 '20 at 09:24

To delete deployment use

$ kubectl delete deploy/old_deployment_name

This will delete deployment, including pods and rs, if you had them.

And dont do this mistake the second time :) @Kamol is right - the best way of managing resources is change config file(e.g your deployment) and re-apply with

kubectl apply -f deployment.yaml

I think we can also remove everything if its installed with the apply command

kubectl apply -f deployment.yaml

you can delete

kubectl delete -f deployment.yaml
