kubectl get all -n Kubernetes-dashboard

If the list is empty, the deletion was successful. You have confirmed that the Kubernetes Dashboard is no longer in your cluster!

Cleaning Up Remaining Resources

After you delete the Kubernetes Dashboard, some items might still remain. These can include services, secrets, or config maps. Finding these leftovers is essential to keeping your cluster tidy.

Checking for Remaining Services

To look for leftover services, run this command:

kubectl get services -n Kubernetes-dashboard

This command will show all services in the dashboard area. If you see any services, they need to be removed.

Deleting Leftover Resources

If you find leftover items, you can delete them one by one. Use this command for each item:

kubectl delete <resource-type> <resource-name> -n Kubernetes-dashboard

Replace <resource-type> and <resource-name> with the real type and name of the item. This will help you remove all unused resources.

Final Cleanup Check

After deleting the leftovers, do a final check. Run this command to see if anything is left:

kubectl get all -n Kubernetes-dashboard

If nothing appears, your cleanup is done. You have successfully removed all remaining items linked to the Kubernetes Dashboard!
