Before you delete Kubernetes Dashboard, you need to find all related items. This includes services, deployments, and other parts linked to the dashboard. Knowing what to remove is essential for a clean deletion.
Checking Resource Status
To see what items are tied to the dashboard, you can run a command. Open your terminal and type:
kubectl get all -n Kubernetes-dashboard
This command will list all items in the dashboard area. You will see services, pods, and deployments. Make sure to check everything before you delete.
Deleting the Resources
Once you know what to delete, you can remove the items. 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 delete everything linked to the dashboard.
Verify Deletion: After you delete the items, check if they are gone. Use the same command to see the list again:

Checking the Status of Kubernetes Dashboard
After you delete Kubernetes Dashboard, it’s essential to check if it is really gone. You can do this by using the command line. Open your terminal and type:

This command will show you the list of services in the dashboard area. If the dashboard is deleted, it will not appear in this list.
Troubleshooting Common Issues
If the dashboard still shows up, there may be a problem. First, check if you are in the right namespace. You can switch to the dashboard namespace with:
kubectl config set-context --current --namespace=kubernetes-dashboard
Then, rerun the delete command. If it still does not work, make sure you have the right permissions.
Checking Pod Status
You should also check the status of the dashboard pods. Run this command:
kubectl get pods -n Kubernetes-dashboard
If the dashboard is deleted, no pods will be listed. This shows that everything related to the dashboard is removed.
Final Verification
To be entirely sure the dashboard is gone, you can list all resources in the namespace. Use this command:
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!
Reinstalling Kubernetes Dashboard (If Needed)
You should reinstall the Kubernetes Dashboard for various reasons. You may have deleted it by mistake or want to get the latest version. Reinstalling can help you get a fresh start on the dashboard.
