How do I remove the Kubernetes dashboard resources from my deployment on Google Cloud Platform?

Question

I've created a Kubernetes deployment. However, there seem to be additional pods running - that I'm hoping to be able to delete the unnecessary ones.

I see no need to run the dashboard container. I'd like to remove it to free up CPU resources.

How can I disable this container from starting up? Preferably from the deployment config.

Essentially the following pod:

kubectl get pods --all-namespaces | grep "dashboard"                                   kube-system   kubernetes-dashboard-490794276-sb6qs                  1/1       Running   1          3d

Update 2021-08

To have a clean removal you must to delete a lot of objects. Overtime removing the dashboard has been a common problem, so you can now do this:

kubectl delete -f https://raw.githubusercontent.com/kubernetes/dashboard/master/aio/deploy/recommended.yaml 

If you don't want to do a blind thing and you want to know what are you removing just try to execute this:

kubectl get secret,sa,role,rolebinding,services,deployments --namespace=kube-system | grep dashboard 

If the output is empty, just double check your dashboard namespace's with the command

kubectl get namespaces 

The dashboard is stored in a separate namespace and, depending of your context, the dashboard can be not always in the same namespace. If you want have a deeper look start trying with kubernetes-dashboard or kube-system and always specify the namespace while callin kubectl.

UPDATE MAY 2020:

Thanks to Lee Richardson for his comment ;)

They have changed the organisation of the files in the repo and as well the command on Kubernetes manual, so the new kubectl delete command needs to be:

kubectl delete -f https://raw.githubusercontent.com/kubernetes/dashboard/master/aio/deploy/recommended.yaml

ORIGINAL POST:

As said before, you can delete the deployment to remove the pods too, running this:

kubectl delete deployment kubernetes-dashboard --namespace=kube-system  

But, if you want to clean all the dashboard related things, you can simply execute the delete command K8s cluster file based in the official Kubernetes manual:

kubectl delete -f https://raw.githubusercontent.com/kubernetes/dashboard/master/aio/deploy/recommended/kubernetes-dashboard.yaml
