Minecraft Java + Bedrock Server Together – Geyser + Floodgate

Minecraft Geyser + Floodgate Paper Minecraft Server
Minecraft Geyser + Floodgate Paper Minecraft Server

This is a new Docker container to automatically set up and run a Minecraft server that both Java and Bedrock players can connect to! This allows everyone to play on your server no matter which edition of Minecraft you are using. It uses the Geyser and Floodgate plugins to accomplish this.

Since it uses the Paper Minecraft server it also supports any additional plugins that are compatible with Paper / Spigot. This gives you the ability to do many things that are currently impossible to do in Bedrock if you are hosting the official Bedrock dedicated server.

It is fully compatible with my Paper Minecraft Java Server Container and you can swap between these two containers without changing any configuration.

The official GitHub page is located here.

The Docker Hub page for the container is located here.

It’s now possible to convert your worlds between Bedrock and Java versions. Check out my guide on Chunker here for more information.

Features

  • Sets up fully operational Minecraft server that allows both Java and Bedrock clients to connect
  • Runs the highly efficient “Paper” Minecraft server
  • Runs Geyser to allow Bedrock clients to connect and Floodgate to allow them to authenticate with their Bedrock credentials to a Java server
  • Plugin support for Paper / Spigot / Bukkit
  • Uses named Docker volume for safe and easy to access storage of server data files (which enables more advanced Docker features such as automatic volume backups)
  • Installs and configures OpenJDK 18
  • Automatic backups to minecraft/backups when server restarts
  • Full logging available in minecraft/logs folder
  • Updates automatically to the latest version when server is started
  • Runs on all Docker platforms including Raspberry Pi

Usage

First you must create a named Docker volume. This can be done with:

docker volume create yourvolumename

Now you may launch the server and open the ports necessary with one of the following Docker launch commands.

With default ports:

docker run -it -v yourvolumename:/minecraft -p 25565:25565 -p 19132:19132/udp -p 19132:19132 --restart unless-stopped 05jchambers/legendary-minecraft-geyser-floodgate:latest

With custom ports:

docker run -it -v yourvolumename:/minecraft -p 12345:12345 -e Port=12345 -p 54321:54321/udp -p 54321:54321 -e BedrockPort=54321 --restart unless-stopped 05jchambers/legendary-minecraft-geyser-floodgate:latest

With a custom Minecraft version (add -e Version=1.X.X, must be present on Paper’s API servers to work):

docker run -it -v yourvolumename:/minecraft -p 25565:25565 -p 19132:19132/udp -p 19132:19132 -e Version=1.17.1 --restart unless-stopped 05jchambers/legendary-minecraft-geyser-floodgate:latest

With a maximum memory limit in megabytes (optional, prevents crashes on platforms with limited memory, -e MaxMemory=2048):

docker run -it -v yourvolumename:/minecraft -p 25565:25565 -p 19132:19132/udp -p 19132:19132 -e MaxMemory=2048 --restart unless-stopped 05jchambers/legendary-minecraft-geyser-floodgate:latest

Using a custom timezone:

docker run -it -v yourvolumename:/minecraft -p 25565:25565 -p 19132:19132/udp -p 19132:19132 -e TZ="America/Denver" --restart unless-stopped 05jchambers/legendary-minecraft-geyser-floodgate:latest

Skipping backups on a certain folder:

docker run -it -v yourvolumename:/minecraft -p 25565:25565 -p 19132:19132/udp -p 19132:19132 -e NoBackup="plugins" --restart unless-stopped 05jchambers/legendary-minecraft-geyser-floodgate:latest

Skipping permissions check:

docker run -it -v yourvolumename:/minecraft -p 25565:25565 -p 19132:19132/udp -p 19132:19132 -e NoPermCheck="Y" --restart unless-stopped 05jchambers/legendary-minecraft-geyser-floodgate:latest

Change number of backups:

docker run -it -v yourvolumename:/minecraft -p 25565:25565 -p 19132:19132/udp -p 19132:19132 -e BackupCount=1 --restart unless-stopped 05jchambers/legendary-minecraft-geyser-floodgate:latest

Configuration / Accessing Server Files

The server data is stored where Docker stores your volumes. This is typically a folder on the host OS that is shared and mounted with the container. I’ll give the usual locations here but if you’re having trouble just do some Googling for your exact platform and you should find where Docker is storing the volume files.

You can find your exact path by typing:

docker volume inspect yourvolumename

This will give you the fully qualified path to your volume like this:

{
        "CreatedAt": "2022-05-09T21:08:34-06:00",
        "Driver": "local",
        "Labels": {},
        "Mountpoint": "/var/lib/docker/volumes/yourvolumename/_data",
        "Name": "yourvolumename",
        "Options": {},
        "Scope": "local"
}

On Linux it’s typically available at:

/var/lib/docker/volumes/yourvolumename/_data

On Windows it’s at

C:\ProgramData\DockerDesktop

but may be located at something more like

\wsl$\docker-desktop-data\version-pack-data\community\docker\volumes\

if you are using WSL (Windows Subsystem for Linux).


On Mac it’s typically

~/Library/Containers/com.docker.docker/Data/vms/0/

If you are using Docker Desktop on Mac then you need to access the Docker VM with the following command first:

screen ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/tty

You can then normally access the Docker volumes using the path you found in the first step with docker volume inspect.

Most people will want to edit server.properties. You can make the changes to the file and then restart the container to make them effective.
Backups are stored in the “backups” folder
Log files with timestamps are stored in the “logs” folder.

Plugin Support for Paper / Spigot / Bukkit

This is a “Paper” Minecraft server which has plugin compatibility with Paper / Spigot / Bukkit.

Installation is simple. There is a “plugins” folder on your Docker named volume.

Navigate to your server files on your host operating system (see accessing server files section if you don’t know where this is) and you will see the “plugins” folder.

You just need to drop the extracted version of the plugin (a .jar file) into this folder and restart the container. That’s it!

Some plugins have dependencies so make sure you read the installation guide first for the plugin you are looking at.

A popular place to get plugins is: dev.bukkit.org

Troubleshooting Note – Oracle Virtual Machines

A very common problem people have with the Oracle Virtual Machine tutorials out there that typically show you how to use a free VM is that the VM is much more difficult to configure than just about any other product / offering out there.

It is because there are several steps you need to take to open the ports on the Oracle VM. You need to both:

  • Set the ingress ports (TCP/UDP) in the Virtual Cloud Network (VCN) security list
  • *and* set the ingress ports in a Network Security Group assigned to your instance

Both of these settings are typically required before you will be able to connect to your VM instance. This is purely configuration related and has nothing to do with the script or the Minecraft server itself.

I do not recommend this platform due to the configuration difficulty but the people who have gone through the pain of configuring an Oracle VM have had good experiences with it after that point. Just keep in mind it’s going to be a rough ride through the configuration for most people.

Troubleshooting Note – Hyper-V

There is a weird bug in Hyper-V that breaks UDP connections on the Minecraft server. The easy workaround for this is that you have to use a Generation 1 VM with the Legacy LAN network driver.

There is a second fix that was shared by bpsimons here. For that fix you need to install ethtool first with sudo apt install ethtool. Next in your /etc/network/interfaces file add “offload-tx off” to the bottom as the issue appears to be with TX offloading.

Here’s an example:

# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.5
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
offload-tx off

This can also be done non-persistently with the following ethtool command:

ethtool -K eth0 tx off

Additional Support

The comments section right here is the best place for support. The second best place is the GitHub issues section.

I will add additional documentation based on what problems people are running into / questions people are asking because right now I’m not really sure what those will be yet. Definitely let me know if you need any of these things!

Question for everyone running this server. Is there a bukkit plug-in for proximity voice chat that works for both Java and Bedrock players?

Hey James,

I feel like I must be missing something really simple here. I am trying to restore a from a backup, but when I decompress the backup into the minecraft folder and start the container nothing changes. I am shutting down the container before decompressing.

I am at a loss. I’ve done this before and never had a problem.

Late reply but make sure you remove the old container and start a new one using the docker run command you ran previously

Hello,
i´ve tried out a dev built of viaversion. That worked! Now starting the container this dev-version will be overwritten and the error occured again. How can I prevent this version from being overwritten at startup?
Best regards

Hey Michael, double check your Java version. You may need to update. I have the same issue, but 1.20.1 requires Java 22.
I’m still trying to sort out just how to get it updated myself as I’m running Java 19.0.2. I’ve pulled openjdk:22 but need to figure out how to point the minecraft server towards it yet… Still stuck on 19, and everything I’ve read says need to update or nothing is really going to work.

Hopefully it works! If you figure out a way to get this container to look at J22 before me, let me know! I’ll do the same.

I have the server running on a Pi4 under Ubuntu server. Unfortunately, I can’t find OpenJDK V22 there. I have now installed Java version 23 from ZULU. Unfortunately, the error still persists: failed to open viaversion.jar. However, I have manually put the latest viaversion5.0.5.jar into the plugin folder. I still get the error message, but then the server starts this version and the server runs.

Hello James, thx for your work and support! I will try to update the container by myself, but myabe you can explain by an example for viaversion. I´m running version 1.21.3. In the plugin-folder is an file calles viaversion, which is 9.758kb big. On the internet there exist an snapshot-version of viaversion, which is about 4.939.465kb big. How do I have to change which script, that the container download the correct last version of viaversion?
Best regards
