使用Docker部署DomJudge

首先要在/etc/default/grub中的GRUB_CMDLINE_LINUX_DEFAULT内增加这一段代码：cgroup_enable=memory swapaccount=1 systemd.unified_cgroup_hierarchy=0，开启cgroup。不然判题机跑不起来。

然后将以下配置文件保存为docker-compose.yaml并对密码进行修改，其中JUDGEDAEMON_PASSWORD先留空。

version: '3.9'

      - JUDGEDAEMON_PASSWORD=

完成后运行docker-compose up -d。

tips:如果此时报错说docker-compose版本过低，可以参考如何更新docker-compose解决。

这时候已经可以访问127.0.0.1:12345打开domjudge了。你可以修改配置以监听0.0.0.0:12345或者使用nginx反代。

运行docker exec -it domserver cat /opt/domjudge/domserver/etc/initial_admin_password.secret获取admin密码。这时候已经可以登录后台了。

这时判题机还是没启动，运行docker exec -it domserver cat /opt/domjudge/domserver/etc/restapi.secret 获取JUDGEDAEMON_PASSWORD并填入docker-compose.yaml中。再运行docker-compose up -d即可。

数据库中的数据已经进行持久化配置，在docker-compose.yaml同目录的data中。需要迁移时只需要迁移这个文件夹即可。
