 # Cleaning Up
 
-In this lab you will delete the compute resources created during this tutorial.
+In this lab you will delete the resources created during this tutorial.
 
-## Compute Instances
+## Virtual Machines
 
-Delete the controller and worker compute instances:
+Stop the 7 VM created for this tutorial:
 
 ```bash
-gcloud -q compute instances delete \
-  controller-0 controller-1 controller-2 \
-  worker-0 worker-1 worker-2 \
-  --zone $(gcloud config get-value compute/zone)
+sudo shutdown -h now
+```
+
+Delete all the VMs via the Proxmox WebUI or the Proxmox CLI (on the hypervisor):
+
+```bash
+sudo qm destroy <vmid> --purge
 ```
 
 ## Networking
 
-Delete the external load balancer network resources:
-
-```bash
-{
-  gcloud -q compute forwarding-rules delete kubernetes-forwarding-rule \
-    --region $(gcloud config get-value compute/region)
-
-  gcloud -q compute target-pools delete kubernetes-target-pool
-
-  gcloud -q compute http-health-checks delete kubernetes
-
-  gcloud -q compute addresses delete kubernetes-the-hard-way
-}
-```
-
-Delete the `kubernetes-the-hard-way` firewall rules:
-
-```bash
-gcloud -q compute firewall-rules delete \
-  kubernetes-the-hard-way-allow-nginx-service \
-  kubernetes-the-hard-way-allow-internal \
-  kubernetes-the-hard-way-allow-external \
-  kubernetes-the-hard-way-allow-health-check
-```
-
-Delete the `kubernetes-the-hard-way` network VPC:
-
-```bash
-{
-  gcloud -q compute routes delete \
-    kubernetes-route-10-200-0-0-24 \
-    kubernetes-route-10-200-1-0-24 \
-    kubernetes-route-10-200-2-0-24
-
-  gcloud -q compute networks subnets delete kubernetes
-
-  gcloud -q compute networks delete kubernetes-the-hard-way
-}
-```
+Delete the private Kubernetes network (`vmbr8`) via the Proxmox WebUI (to avoid fatal misconfiguration).
