1. git clone git@gitlab.com:saurshaz/my-py-app.git
2. snap install docker
3. snap start docker
4. docker-compose up --build
5. make changes to app folder for code and they'll be reflected immediately

access docker shell directly

(good to know, might be needed)

• docker exec -i -t 6e24d2de3709 /bin/sh
