下載JudgeServer程式碼
#git clone https://github.com/QingdaoU/JudgeServer.git
切換目錄
#cd JudgeServer
查看Dockerfile，「git clone -b newnew --depth 1 https://github.com/QingdaoU/Judger && cd Judger 」，此JudgeServer會去下載Judge。
建立印像檔
#docker build . -t oj/judge-server:v1
如果已經執行online judge，先停止執行online judge
#docker-compose down
編輯docker-compose.yml，judge-server使用印像檔oj/judge-server:v1
judge-server:
image: oj/judge-server:v1
重新啟用online judge
#docker-compose up -d
