These Dockerfiles allow you to run DOMjudge inside a Docker container.

Use Docker Compose to build the images:

$ docker-compose -f docker-compose-domserver.yml up
$ docker-compose -f docker-compose-judgehost.yml up --build

You may want to edit domserver/apache.conf.in to enable TLS or tweak the PHP upload restrictions.

All environment variables can be set in the relevant *.env files.

The domserver compose file comes bundled with a MariaDB container. If you want to use this, you only need to specify a password for the mysql root user and for the domjudge user by setting MYSQL_ROOT_PASSWORD to the root password, and MYSQL_PASSWORD to the domjudge user password. You can also use a standalone MySQL server. In that case, you need to specify the MYSQL_HOST variable. It is also possible to specify a database name and domjudge user name (both default to domjudge) by setting MYSQL_DATABASE and MYSQL_USER.

If you use a reverse proxy, you need to set TRUSTED_PROXIES to the IP or host name of your proxy.

You can also specify a timezone by setting the CONTAINER_TIMEZONE variable.

As for the judgehost, you need to run the container in privileged mode to use cgroups. You also need to specify the domserver URL and judgehost user password by setting DOMSERVER_HOST, DOMSERVER_PASSWORD. You can set DOMJUDGE_USER as well, but it defaults to judgehost. You should also specify a hostname for this container to identify it in the domserver.

If you want to support more programming languages, you need to edit judgehost/languages to enable/disable languages. If a language you want isn't listed, feel free to create an issue or submit a pull request!

You also need to specify the following kernel parameters on the container host for cgroups: cgroup_enable=memory swapaccount=1.

You can customize the DOMjudge source by adding patches to the patches directories.

The ICPC tools can be used by domjudge with some workarounds. After setting up the contest and autojudges, the following steps can be used to get several tools working.

Make sure the contest is created and active

• Create an user for the event feed (e.g. event) with the role API_READER and Source

• Update the passwords and contest id in cds.env

• Start the contest data server

  $ docker-compose -f docker-compose-cds.yml up --build

• Verify everything works by going to https://<host>:8443/contests/<contest-id> (The first time you visit this link, it will retrieve the data.)

Add in the photos directory the images as jpg or png that you want to make available to the presentations client. Select the Photos presentation to display the images.

Download the latest version of Presentation Controller and unzip the file. Run the following command to connect to the cds

	$ ./presAdmin.sh https://<cds-host> admin <adminPassword>

Download the latest version of Presentation Client and unzip the file. Run the following command to the connect to the cds.

	$ ./client.sh <clientName> https://<cds-host>/api/contests/<contest-id> presentation <presentation-password>

Download the latest version of the Resolver and unzip the file. Generate the standing by running the awards script and connect to your cds using the url https://<cds-host>/api/contests/<contest-id> with the admin account.

Setup the standings as desired and save the file as awards.json.

Now the scoreboard can be resolved with custom places and awards by executing

    $ resolver event-feed.json
