Terraria

[UPDATE] I know a lot of people are excited for Terraria v1.4 Journey's End! This source code is built around the pre-release of TShock. Will continue to update as new releases come out.

This project is a Dockerfile to containerize TShock and Terraria TerrariaServer.exe to run on linux. Docker will remove the need for someone to worry about how to setup a server in linux with all the right dependencies to run. The installation and usage instructions are written with complete beginners in mind.

Quick start guide

First you need a linux machine with Docker installed. Everything from here on out assumes the docker service is running (you may need to start the service after install).

Create directory to save your world to

Next create a directory for your world file, configuration, and logs

mkdir -p $HOME/terraria/world

Creating a fresh world

For the first run you will need to generate a new world with a size where: 1=Small, 2=Medium, 3=Large

sudo docker run -it -p 7777:7777 --rm -v $HOME/terraria/world:/root/.local/share/Terraria/Worlds ryshe/terraria:latest -world /root/.local/share/Terraria/Worlds/<world_name_here>.wld -autocreate <world_size_number_here>

Note: If you close the the terminal, the server will stop running. You will need to restart with a preexisting world. It may be worth while to close after creation anyway to update the initial config.json settings.

To create a world with a few more initial options, you can do so in an interactive mode.

sudo docker run -it -p 7777:7777 --rm -v $HOME/terraria/world:/root/.local/share/Terraria/Worlds ryshe/terraria:latest

To start with a preexisting world

sudo docker run -d --rm -p 7777:7777 -v $HOME/terraria/world:/root/.local/share/Terraria/Worlds --name="terraria" -e WORLD_FILENAME=<.wld world_filename_here> ryshe/terraria:latest

Note: This command is designed to run in the background, and it is safe to close the terminal window.

Any config.json in the directory will automatically be loaded. The <world_file_name>.wld should be the name of your wld file in your $HOME/terraria/world directory.

Updating your container

Updating is easy!

Grab the latest terraria container
```
docker pull ryshe/terraria:latest
```
First we need to find our running container to stop, so we can later restart with the latest
```
docker container ls | grep ryshe/terraria
```
The first few numbers and letters, on a line, are the container hash. Remember the first 3 or so letters or numbers

Example:
```
f25261ac55a4        ryshe/terraria:latest   "/bin/sh bootstrap.s…"   3 minutes ago       Up 3 minutes        0.0.0.0:7777->7777/tcp, 7878/tcp   reverent_solomon
```
f25 would be the first few letters/numbers of the container hash

NOTE: If you see multiple lines, find the one that still has an up status.

Stop and remove the container

docker container rm -f xxx # xxx is the letters/numbers from the last step

Start your container again with your world (see the Quick start)

[Virtual] Machine Setup

Provision a linux machine that can support docker and containerization. For more information visit docker. For a small or medium world with no more than 8 users a linux machine with 1-1.5GB of ram should suffice. If you are running a vm in the cloud, make sure to expose tcp port 7777 and udp port 7777.

Before starting the build process make sure the latest tshock version is specified in the Dockerfile under

ADD https://github.com/Pryaxis/TShock/releases/download/v4.4.0-pre1/TShock_4.4.0_226_Pre1_Terraria1.4.0.2.zip /

Building from source

Assuming git and docker are installed..

Clone this repository

git clone https://github.com/ryansheehan/terraria.git

Open a terminal window into the directory downloaded by the git
Build the container
```
docker build -t <name_here> .
```

Running a container image

Whether you build your own container, or use my container published to docker hub, we are ready to run our terraria server!

Note: For a full set of docker run options go here

First run

The first run of the server will give you the opportunity to create a world, and it will generate the server's config file. You may wish to add the config file for many reasons, but one of which is to add a password to your server.

docker run -it --rm -p 7777:7777 -v $HOME/terraria/world:/root/.local/share/Terraria/Worlds ryshe/terraria:latest

Let's break down this command:

Command Part	Description
`docker run`	tells linux to run a docker image
`-it`	run interactively and output the text to terminal
`--rm`	remove docker container when the container stops or fails
`-p 7777:7777`	exposes terraria port <host machine side>:<container side>
`-v $HOME/terraria/world:/root/.local/share/Terraria/Worlds`	maps a folder on the host machine into the container for saving the .wld file. This does not have to be `$HOME/terraria/world`. Anything left of the `:` is host machine directory
`ryshe/terraria`	the name of the image. This could be your image if you build from source
`:latest`	the tag, which defaults to `latest` if not specified. `latest` is the most recently published container

The config file can be found in the directory specified by the -v volume.
If the terminal window is shut down, that will exit the process. Make sure to do so after the world is created!

Running with an existing generated world

After a world has been generated, you may want to load directly into it.

docker run -d --rm -p 7777:7777 -v $HOME/terraria/world:/root/.local/share/Terraria/Worlds ryshe/terraria:latest -world /root/.local/share/Terraria/Worlds/<world_filename_here>.wld

Let's break down the command:

Command Part	Description
`-d`	run this in the background. It is okay to close the terminal window, the container will continue to run
`-world /root/.local/share/Terraria/Worlds/<world_filename_here>.wld`	specifies the world file name you wish to immediately load into

for the other parts check out the First run section
check out additional server startup flags here. They go on after the ryshe/terraria:latest portion of the line

Docker Compose example with previously generated world

Here is a sample docker compose file that can be used to start the server. The command option lets you pass the flags needed to load the world and the config file. The stdin_open and tty options are a workaround to running the container in detached mode without crashing the server.

(Note for Podman users: Ensure to add the :Z flag to the volume to give the container access to the volume.)

version: "3"
services:
  terraria:
    container_name: terraria
    image: ryshe/terraria:latest
    stdin_open: true # docker run -i
    tty: true # docker run -t
    environment:
      - WORLD_FILENAME=world.wld
      - CONFIGPATH=config.json
    ports:
      - 7777:7777
    volumes:
      - <world-dir-location>:/root/.local/share/Terraria/Worlds
    restart: unless-stopped

Plugin support

A volume exists to support plugins. Create a folder, not inside your /world folder, for your plugins

mkdir ServerPlugins

Mount the plugins directory with an additional -v switch on your docker run ... command

-v <path_to_your_ServerPlugins_folder>:/plugins

Environment variables

Ability to overwrite file locations and file names

Vanilla

ENV LOGPATH=/terraria-server/logs
ENV WORLDPATH=/root/.local/share/Terraria/Worlds
ENV WORLD_FILENAME=""
ENV CONFIGPATH=/config
ENV CONFIG_FILENAME="serverconfig.txt"

Logs

A separate directory can be volumed in for storing logs outside of the image

-v <path_to_store_logs>:/tshock/logs

Notes

sudo may be required to run docker commands.
Please post to the TShock team with questions on how to run a server.
Any additional command-line instructions can be added to the end of either method for launching a server. Docker maps the $HOME/terraria/world linux-host folder to the /tshock/world container-folder.
Expecting your server to run for a while? Add --log-opt max-size=200k to limit your log file size. Otherwise one day you will wake up to see all your hdd space chewed up for a terraria docker setup!
