• chmod +x config.sh config2.sh
• ./config.sh

Now docker installation has been completed Note: You may have to logout (or restart your machine) to allow Docker to run without sudo

Instructions to create Docker image from Dockerfile [./backend/src/judge/Dockerfile]

• open a new terminal
• cd path/to/CodeAreaMaster/
• ./config2.sh Third step may take some time

If above script give the error (Can't connect to docker daemon) during hello-world installation It means docker is not allowed to run without sudo (running docker without sudo is required) Please logout from the system (or restart your computer). It will fix the issue.

pip install -r requirements.txt

A virtual environment is recommended. Later inside that directory, run the following command:

python manage.py makemigrations
python manage.py migrate

This would create the necessary tables in the postgres database. Make sure the username and password of your database is set in DATABASE variable in settings.py found in backend/src/codearea.

To create a superuser, run the following command

python manage.py createsuperuser

Next go to the admin panel found in host:port/admin/, then to the languages sections found in '/admin/submissions/language/' and add the following languages:

• C

• python2
• python3
• java
• golang

• add path to python(anaconda3)
• set working directory according to given example
• follow these commands
  1. sudo mv codearea.service /etc/systemd/system
  2. sudo systemctl enable codearea
