##Installation ###Prerequisites Disclaimer: GoOnlineJudge works best on GNU/Linux and has been tested on Ubuntu 14.04 and Arch Linux. Windows and Mac OS X are not recommended because RunServer cannot be built on both of them.

If you are Windows or Mac OS X user, you can try out docker-oj, based on docker image and works out of the box.

docker build -t oj .
docker run --link your_mongo:mongodb --name oj  -e DATA_PATH=your_data_path -e JUDGE_HOST=your_judge_host -v your_data_path:your_data_path -d -p 80:8080 oj

If you installed mongodb on your host os, use script like this:

cat > env_file << EOF
MONGODB_USERNAME=test
MONGODB_PASSWORD=password
MONGODB_PORT_27017_TCP_ADDR=192.168.1.1
MONGODB_PORT_27017_TCP_PORT=27017
MONGODB_INSTANCE_NAME=test
DATA_PATH=your_data_path
JUDGE_HOST=your_judge_host
EOF

docker run --env-file env_file --name oj -v your_data_path:your_data_path -d -p 80:8080 oj
