+# 11. Cleanup
+
+Estimated time: 4 min remaining
+
+Time for some cleaning of the resources used (to save on cost and to be a good cloud citizen).
+
+To delete the dervice, we need to get the service name first:
+```sh
+$ kubectl get service
+NAME                       CLUSTER-IP    EXTERNAL-IP       PORT(S)    AGE
+hello-node-2142604176-x8   10.124.132.1   123.132.123.151   8080/TCP   1h
+```
+Then we can delete the service, which also deletes your external load balancer:
+```sh
+kubectl delete services hello-node-2142604176-x8
+service "hello-node-2142604176-x8" deleted
+```
+
+Delete the running pods:
+```sh
+$ kubectl delete rc hello-node
+```
+Delete your cluster:
+```sh
+$ gcloud container clusters delete hello-world
+   Waiting for cluster deletion...done.
+   name: operation-xxxxxxxxxxxxxxxx
+   operationType: deleteCluster
+   status: done
+   target: /projects/kubernetes-codelab/zones/us-central1-f/clusters/hello-world
+   zone: us-central1-f
+```
+This deletes the Google Compute Engine instances that are running the cluster.
+
+Finally delete the Docker registry storage bucket hosting your image(s):
+```sh
+$ gsutil ls
+gs://artifacts.<PROJECT_ID>.appspot.com/
+$ gsutil rm -r gs://artifacts.<PROJECT_ID>.appspot.com/
+Removing gs://artifacts.<PROJECT_ID>.appspot.com/...
+```
+Of course, you can also delete the entire project but note that you must first disable billing on the project. 
+Additionally, deleting a project will only happen after the current billing cycle ends.
