+## Minecraft server
+This example defines a basic setup for a Minecraft server. More details on the Minecraft server docker image can be found [here](https://github.com/itzg/docker-minecraft-server/blob/master/README.md).
+
+Project structure:
+```
+.
+├── docker-compose.yaml
+└── README.md
+```
+
+[_docker-compose.yaml_](docker-compose.yaml)
+```
+services:
+ minecraft:
+   image: itzg/minecraft-server
+   ports:
+     - "25565:25565"
+    ...
+  volumes:
+     - "~/minecraft_data:/data"
+```
+
+When deploying this setup, docker-compose maps the Minecraft server port 25565 to
+the same port of the host as specified in the compose file. The Minecraft client application can connect to this port directly.
+This example maps the Minecraft data folder holding all game storage to ~/minecraft_data on the host.
+
+## Deploy with docker-compose
+
+```
+$ mkdir -p ~/minecraft_data
+$ docker-compose up -d
+WARNING: Some services (minecraft) use the 'deploy' key, which will be ignored. Compose does not support 'deploy' configuration - use `docker stack deploy` to deploy to a swarm.
+Creating network "minecraft_default" with the default driver
+Creating minecraft_minecraft_1 ... done
+```
+
+Note: this is using a volume in order to store Minecraft server data, that can be recovered if you remove the container and restart it. 
+
+## Expected result
+
+Check containers are running and the port mapping:
+
+```
+$ docker ps
+CONTAINER ID        IMAGE                   COMMAND             CREATED             STATUS                   PORTS                                 NAMES
+7f696c2fb101        itzg/minecraft-server   "/start"            5 minutes ago       Up 5 minutes (healthy)
+```
+
+After running `docker-compose up`, the minecraft server takes a bit of time to initialize Minecraft world. You can follow the progress:
+
+```
+$ docker-compose logs
+...
+minecraft_1  | [15:06:39] [Worker-Main-6/INFO]: Preparing spawn area: 94%
+minecraft_1  | [15:06:39] [Worker-Main-7/INFO]: Preparing spawn area: 94%
+minecraft_1  | [15:06:39] [Server thread/INFO]: Time elapsed: 25620 ms
+minecraft_1  | [15:06:39] [Server thread/INFO]: Done (35.526s)! For help, type "help"
+minecraft_1  | [15:06:39] [Server thread/INFO]: Starting remote control listener
+minecraft_1  | [15:06:39] [Server thread/INFO]: Thread RCON Listener started
+minecraft_1  | [15:06:39] [RCON Listener #1/INFO]: RCON running on 0.0.0.0:25575
+```
+
+Once it is initialized, run your Minecraft application, hit "Play", then "Multiplayer" and "Add server"
+![add server](screenshots/click-add-server.png)
+
+ Specify your new server IP : localhost:25565
+ ![server configuration](screenshots/add-server-config.png)
+
+ You can then start playing
+ ![ready to play](screenshots/ready-to-play.png)
+
+Stop and remove the containers
+
+```
+$ docker-compose down
+```
+
+To delete all data, remove all named volumes by passing the -v arguments:
+
+```
+$ docker-compose down -v
+```
