Don't Starve Together Dedicated Server Docker Image

They write their server setup instructions like sh*t, so we made this Docker image to simplify things.

Please read the whole document before putting your hands on your server.

Versioning

The server code changes a lot. We offer 2 update channels on Docker Hub:

jamesits/dst-server:latest is a less frequently updated image (it is only updated when Dockerfile changes), and the server code will be updated on every launch
jamesits/dst-server:nightly is a nightly built image, so it (hopefully) comes with the latest server code (the server code will still be updated on every launch)

Running

Prerequisites

Linux x86_64 and runs Docker (18.05.0-ce or later).
You may need a public IP to make your server accessable from Internet.
You need 4 UDP ports exposed to the public network. (See FAQ for details.)
CPU: 1 core is somewhat enough for a small-scale server (but don't try 60 ticks, start from 15 or 30).
Memory: We recommend reserving 1GiB Memory for the server, plus 60MiB per active user.
Disk size: the Docker image takes 1.5GiB, and you need at least another 5MiB for maps, configs and logs. 4GiB available disk space is recommended.

Start server

Let's assume you are saving your server config and status to ${HOME}/.klei/DoNotStarveTogether. (This is the default location when it is running outside Docker, so we'll use this as an example. If you want to save it to other location, just mount that directory read-write to the /data folder of the container.)

Start server:

docker run -v ${HOME}/.klei/DoNotStarveTogether:/data -p 10999-11000:10999-11000/udp -p 12346-12347:12346-12347/udp -it jamesits/dst-server:latest

If you use docker-compose, an example config is provided.

Stop server

Just press Ctrl+C and wait a little while to let itself spin down. (If the server is saving data, don't press ^C twice to force kill the server.)

To programmatically shut down the server, send a SIGINT to the supervisord process.

Note: the server may take up to ~5min to save map and fully shut down.

Server Configuration

If you don't already have a set of server config in your data directory, we will generate one for you. Start server once using the command above, and you will see:

Creating default server config...
Done, please fill in `DoNotStarveTogether/Cluster_1/cluster_token.txt` with your cluster token and restart server!

Open a genius copy of Don't Starve Together client, log in, click "account" button on the bottom left of the main menu, and generate a new token from the pop-up web page. Then open your_data_directory/DoNotStarveTogether/Cluster_1/cluster_token.txt on your server using any text editor, paste the token, save.

Don't forget to edit your_data_directory/DoNotStarveTogether/Cluster_1/cluster.ini and get your server an unique name!

After you finish this, re-run start server command, and the server should be running.

Build Docker image locally

(In most cases you don't need this; just pull the prebuilt image from Docker Hub.)

git clone https://github.com/Jamesits/docker-dst-server.git docker-dst-server
cd docker-dst-server
docker build . -t dst-server:latest

Known Issues

On Docker environment which doesn't support UDP port forwarding, LAN only server cannot be used. (Still you can enable Steam punchthrough and search for your server in Online catalog. )
Docker IPv6 support is another sh*t and we currently don't have any idea on it. Help and advices are always welcomed. (see #7.)

FAQ

How to update server or mods?

Restart the server. Updates will be downloaded automatically.

How to connect to a LAN only server?

Run c_connect("IP address", port) or c_connect("IP address", port, "password") in client console.

How to check if the server is online?

You can try the 3rd party website Don't Starve Together Server List.

What port does this server require?

You need to expose UDP 10999 (master) and 11000 (caves) for client to connect; udp 12346 and 12347 for steam connection. Don't NAT these ports to different port numbers.

The server use another 2 high UDP ports for unknown communication, and UDP 10998 (listen on localhost) for communication between cluster servers.

Here is a netstat -tulpn output on our test server:

Error! App '343050' state is 0x202 after update job.

Your disk is full.

Client high latency or lagging

Possible causes:

High packet drop rate
High server tick rate with low-performance clients (e.g. notebook users with tick rate 60)
