Setup Guide

1. Set up docker

2. Download images from Docker Hub

docker pull xiaokang00010/image-judger
docker pull xiaokang00010/image-judger-scheduler
docker pull xiaokang00010/image-web-service

3. Create and start containers

docker container create --name web -p <oj port>:5914 xiaokang00010/image-web-service
docker container create --name judger-1 xiaokang00010/image-judger
docker container create --name judger-scheduler xiaokang00010/image-judger-scheduler
docker container start web
docker container start judger-1
docker container start judger-scheduler

4. Get IP address in logs

Now you should get IP address of each container. And memorize them, it will be used in next steps.

docker logs --tail 100 web # use ^C to exit
docker logs --tail 100 judger-1 # use ^C to exit
docker logs --tail 100 judger-scheduler # use ^C to exit

5. Configure Web Services

Use the following command to connect to container.

docker container -it exec web /bin/bash

Then, chdir to /var/zqhf-oj-v2/backend/src/

Edit the config.json, replace the judger-server-address with the address of container judger-scheduler like <ip address>:5918.

And, restart the web container.

6. Configure the Judger Scheduler

Use the following command to connect to container.

docker container -it exec judger-scheduler /bin/bash

Then, edit /var/zqhf-oj-v2/judgeScheduler/config.py, set judger_hosts to ["<judger-1 IP>:5917"], if you have not only one container for judge. You can set judger_hosts to ["<judger-1 IP>:5917", "<judger-2 IP>:5917", "<judger-... IP>:5917"]

And, restart the judger-scheduler container.

7. Now you can open localhost:5914 in your browser, and login with username admin, password zqhf-oj-v2.
