For development, you can do theses things :
1) Keep the container awake with a non-stop command ( ex: CMD tail -f /dev/null)

FROM python:3.9.0

...

COPY requirements.txt /data/requirements.txt
RUN pip install -r requirements.txt
COPY . .

# Keep the container awake
CMD tail -f /dev/null
Enter fullscreen mode Exit fullscreen mode

2) Bind a volume on your container (with docker-compose.yml)

version: "3"
services:
  app:
    build:
      context: .
      dockerfile: Dockerfile.local
    volumes:
      - .:/data/
    environment:
      - TZ=Europe/Paris
    ports:
      - "8000:8000"
    networks:
      - default
Enter fullscreen mode Exit fullscreen mode

3) Use a development server with hot-reloader (runserver for Django, run for flask, react-scripts start for Reactjs, etc)
