Backend for Online Seminar of Informatics

ksi.fi.muni.cz

Running with docker

The backend can be run inside a docker container for testing purposes. To build the image, run:

docker-compose up --build

This will build the image and start the container, together with development versions of the frontend.

• backend will be running at http://localhost:3030
• frontend will be running at http://localhost:4201
• old frontend will be running at http://localhost:8080

The master account is admin@localhost with password change-me.

The backend is created together with a sample seminar repository. To use the repository, you must clone it locally after starting the container:

git clone .docker/data/seminar.git seminar-dev

The backend will automatically push and pull from the repository in the container, you can work with your own clone.

Running manually

Running manually is discouraged, as it requires a lot of setup. If you still want to run the backend manually, follow the instructions below.

Software needed

• Python 3.7+
• virtualenv
• packages from requirements.txt
• isolate

Installation

1. Clone this repository.
2. Run init-makedirs.sh.
3. Install virtualenv & packages into ksi-py3-venv directory.

   virtualenv -p python3 ksi-py3-venv

4. Enter db url into config.py file. Format is the same as specified in config.py.dist

6. Run the server, comment the database-create-section in run.py
7. Install isolate with box directory /tmp/box.
8. Bind-mount /etc directory to /opt/etc (this is required for sandbox to work):

   Do not forget to add it to /etc/fstab.
