我有一个在Docker中运行的Django应用程序，虽然我可以更改.py文件，但由于某种原因（我假设Docker阻止了写访问），我不能将更改保存到模板文件。有没有一种方法可以避免容器旋转？
docker-compose.yml

version: '3.8'

services:
  web:
    build: ./app
    command: gunicorn -w 3 myapp.wsgi:application --bind 0.0.0.0:8000 --reload
    volumes:
      - ./app/:/usr/src/app
      - ./static/:/home/app/web/static
      - ./media/:/home/app/web/media
    expose:
      - 8000
    env_file:
      - ./.env
    restart: unless-stopped
  nginx:
    build: ./nginx
    volumes:
      - ./static/:/home/app/web/static
      - ./media/:/home/app/web/media
    ports:
      - 7000:80
    depends_on:
      - web
