如何在Django运行时中进行更改？

Question

I have hard time when developing django on my docker. When I make any changes to the code, I need to restart whole container for the changes to take effect.

I have a filesystem mounted locally and the changes are made locally. But even if I make changes directly in the container, make migrations or touch an affected or wsgi file, the changes do not take any effect.

This is the image in compose file

backend:
    container_name: 'backend'
    image: dronetag/alpha-docker/backend
    build: ./images/backend/
    command: >
        sh -c  "
              python manage.py collectstatic --no-input;
              python manage.py migrate;
              gunicorn backend.wsgi -b 0.0.0.0:80;"
    ports:
      - "10080:80"
      - "10443:443"
    volumes:
      - ./src/backend:/src
    depends_on:
      - postgres
    links:
      - redis
      - postgres

Dockerfile

FROM python:3.6
ENV PYTHONUNBUFFERED 1
ENV C_FORCE_ROOT true
RUN mkdir /src
WORKDIR /src
COPY requirements.txt .
RUN pip install -r requirements.txt

As long as you are in a development environment you can use the django development server and it will refresh everything accordingly.

Just exchange gunicorn backend.wsgi -b 0.0.0.0:80 with python manage.py runserver .

Please note, that this is not suitable for a productive environment. But there you usually do not need hot code reload.
