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 --build
$ 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.
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 DOMJUDGE_DB_ROOT_PASSWORD and
MYSQL_ROOT_PASSWORD to the root password, and DOMJUDGE_DB_PASSWORD to the
domjudge user password. You can also use a standalone MySQL server. In that
case, you need to specify the DOMJUDGE_DB_HOST variable. It is also possible
to specify a database name and domjudge user name (both default to domjudge)
by setting DOMJUDGE_DB_NAME and DOMJUDGE_DB_USER.
You can also specify a timezone by setting the 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 specify the
(Debian) packages to download. 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.
