Overview[edit]

Instructions for hosting a Minecraft server on Synology DSM.

Installation[edit]

The Minecraft servers implemented with Docker containers.

The image used to create the container is itzg/minecraft-server. [1] [2] [3]

Viewing server status[edit]

Note that when using itzg/minecraft-server with docker-compose.yml, the container doesn't appear in the list of containers within the Docker package. Servers configured using docker-compose.yml should always be started and stopped on the command line and not through the Docker package.

  • Synology DSM > Package Center > Docker > Open
  • Container tab

Containers named minecraft-server serve for Minecraft Java Edition, i.e. desktop, laptop.

Containers named minecraft-bedrock-server serve mobile editions of Minecraft, i.e. iPad.

Nintendo Switch consoles can't connect to either of these servers, I think.

Click on a server, then click Action > Details at the top to view the server details, e.g. the port on which the server is running.

Stopping and Starting the server[edit]

docker-compose.yml[edit]

Always start and stop the server on the command line when configuring a server with docker-compose.yml. 

$ sudo docker-compose up -d 
$ sudo docker-compose down

Docker package[edit]

  • DSM > Package Center > Docker > Open
  • Containers > [select minecraft container in the list]
  • Click the on/off toggle to the right

Connecting to the server in Minecraft[edit]

Mac OS[edit]

  • Open Minecraft and make sure to log in to your Microsoft/Minecraft profile.
  • Click Play
  • Servers tab
    • Scroll down to Additional Servers.
    • If the server is not listed, click Add Server.
      • Server Name: [Name to display in the future under "Additional Servers"]
      • Server Address: [IP of Synology DSM]
      • Port: [Can be found under Docker container details]

Upgrading server version[edit]

View the server container in Synology DMS. Stop the server with the icon in the rightmost column, then start the server again. It will upgrade automatically.

Editing server properties[edit]

DSM[edit]

  • DSM > Package Center > Docker > Open
  • Image > [Select minecraft server image] > Launch button
  • Advanced Settings button
  • Environment tab
    • Add or edit server properties here, e.g. SERVER_PORT, WHITELIST, DIFFICULTY

docker-compose[edit]

Follow instruction under Using Docker Compose in the itzg/minecraft-server documentation.

Data files[edit]

By default the data files for the minecraft world are stored in the Docker container.

Copying data files from the Docker container[edit]

See Docker Cookbook for commands to log into the Docker container and copy files from the Docker Container.

Storing data files outside of the Docker container[edit]

[TK]

External access[edit]

Port number[edit]

Port number is specified in docker-compose.yml.

External access[edit]

External access is controlled by the wifi router.

Router admin > Advanced tab > Forwarding > Virtual Servers > Add New...

  • Service Port: [Public port for server]
  • Internal Port: [Minecraft Docker container port (leave blank to mirror public port)]
  • IP Address: [LAN IP address of Synology DSM]
  • Protocol: All
  • Status: Enabled

When connecting use the public URL of the Synology DSM, e.g. dbarchowsky.synology.me and the public port defined in the router.

Whitelist[edit]

In server.properties set white-list=true and enforce-whitelist=true.

Add user names to white-list.txt (one user name per line.)

Add user names and uuid's to white-list.txt.

Restart the server.

As the server starts up it will look up uuid's for the users listed in white-list.txt and add those uuid's and user names to whitelist.json. white-list.txt will then be renamed to white-list.txt.converted.
