Break It on Purpose

You are going to break your server on purpose. Knowing you can undo an experiment is what makes a homelab fun instead of scary.

Delete the dashboard

1. Open Dockhand and select the heimdall stack.
2. Delete the stack, selecting the option to remove its volumes when asked.
3. Open http://CONTAINER-IP:8080. The dashboard should be gone.

Roll it back

1. In Proxmox, select the Debian container and open Snapshots.
2. Select working-dashboard and choose Rollback.
3. Confirm that changes made after the snapshot will be discarded.
4. Wait for rollback to finish. Start the container if Proxmox leaves it stopped.
5. Reload http://CONTAINER-IP:8080 and watch Heimdall return.

The snapshot restored the container’s filesystem and configuration to the moment you captured it. Future experiments can be bold because you now know how to get back.

Clone your working server

Stop the Debian container, then choose More → Clone. Select Full Clone, give it a different hostname such as docker-sandbox, choose a new CT ID, and create it.

Do not start the clone while the original is running: the saved DHCP lease can briefly give both copies the same IP. Start the clone by itself, confirm that it contains the same apps, then stop it. Select the clone and choose More → Remove to delete it, then restart the original.

A clone is a safe sandbox for a larger experiment and a starting template for your next server.

You have proved you can break something and get it back.
