ElDewrito dedicated server

ElDewrito dedicated server dockerized

About

This is a Dockerfile for running the ElDewrito server under Linux. The container uses Wine to run the Windows application and xvfb to create a virtual desktop.

The container is running 100% headless - no GUI is required for installation, execution or configuration.

The game files are required in order to start this container. They are not bundled within the container and you will have to provide them.

Usage

See the docker-compose here (recommended) or manually start the container with the following command:

docker run -d -p 11774:11774/udp -p 11775:11775/tcp -p 11776:11776/tcp -p 11777:11777/tcp -v /path/to/game:/game -v /path/to/config:/config -v /path/to/logs:/logs --cap-add=SYS_PTRACE domistyle/eldewrito

The capability SYS_PTRACE is required due to how ElDewrito works. The server won't start without it.

A default configuration file and veto/voting rules will be created automatically if no configuration exists in the game directory. If you do not want to use this configuration you can override this behavior by creating your own dewrito_prefs.cfg before starting the container.

Tags

The following tags are available:

Name	Description
latest	Direct build from master branch. Generally not recommended.
X.Y-testZ	Tagged builds taken from master branch. Used for testing.
X.Y	Stable tags. Everything was tested and is working. (not available yet)

Tutorial (for Ubuntu hosts)

1. Prepare a Ubuntu host
2. Install Docker for Ubuntu by following this guide
3. Make sure Docker is working by running docker -v
4. Install docker-compose with sudo apt-get install docker-compose
5. Grab the latest compose file from the git repository here
6. Put the docker-compose.yml in a folder called eldewrito
7. Switch into the folder and open the file with nano docker-compose.yml
8. Adjust /path/to/game, /path/to/config, /path/to/logs accordingly
9. Adjust the image you want to use if necessary, e.g. change domistyle/eldewrito to domistyle/eldewrito:0.6-test5
10. Put your Eldewrito game files into the folder you specified for /game
11. Remove the dewrito_prefs.cfg from your game folder to let the container generate a known working one for you
12. Run docker-compose up -d

You're done. Your container will now be running and you can check if it is working by visting http://server_ip:11775 in your browser.

You can use docker ps to view running containers.

To update the container either change the image tag inside of your docker-compose.yml and run docker-compose up -d or use docker-compose pull followed by docker-compose up -d if you are using the latest tag.

You can use docker-compose logs to view the logs inside of the container.

Issues & limitations

• The announce port(s) and listening port(s) can't be configured separately
  • This means you can't take advantage of container/host ports in Docker yet
  • Only 1:1 binding like 11774:11774 is possible for now
• The server is running as root
  • Not a security issue by itself, just bad practice and laziness
• The dewrito_prefs.cfg can't be placed outside of the game directory
• The banlist.txt can't be placed outside of the game directory
• The server.json can't be placed outside of the game directory
• The DedicatedServer.log can't be placed outside of the game directory
