+# docker-compose-setup
+
+The example setup is for running an instance of goblin on your personal server
+using Docker + Docker Compose and Caddy.
+
+The Setup process involves a few simple steps.
+
+1. Create a Caddy Network bridge
+
+```sh
+; docker network create -d bridge caddy_network
+```
+
+> [!NOTE]: Replace `caddy_network` with something else if you already have a
+> similar name for a different cluster and would like to avoid merging the
+> existing caddy services with this one. If merging them is not an issue, please
+> continue with the exiting name.
+
+2. Modify the `Caddyfile` to make sure it has the right domains, the example has
+   `goblin.run`.
+3. Run the Caddy Service, you only need to run this once and just verify it's
+   running by using `docker compose ps`
+
+```sh
+docker compose -f ./docker-compose.yml up -d
+```
+
+4. Now you can run the `goblin` service using the following
+
+```sh
+docker compose -f ./docker-compose.goblin.yml up -d
+```
+
+You can verify the status of the running containers by running the following
+
+```sh
+docker compose ps
+```
+
+You should have the services `caddy-1` and `goblin-1` running and will manage
+the domain mapping for you.
