文件/文件夹 - 映射

# django在处理数据库或者媒体文件持久时需要用到
# nginx在读取媒体文件的时候需要用到

1: 移动静态文件(static media db.sqlite3等) 到定义的宿主机路径: /usr/graduation下

   -- /usr/graduation/static
   -- /usr/graduation/media
   -- /usr/graduation/db.sqlite3
   

docker-compose

# 配置django与nginx的映射磁盘文件，以及启动容器的配置镜像，方便后面的读取

version: '3.4'
services:

  django:
    image: graduation-web
    build:
      context: .
    container_name: graduation-web
    volumes:
      # 宿主机路径      :    容器路径
      - /usr/graduation/static:/apps/graduation/static
      - /usr/graduation/media:/apps/graduation/media
      - /usr/graduation/db.sqlite3:/apps/graduation/db.sqlite3
    ports:
      - 端口号:端口号

  nginx:
    image: nginx
    restart: always
    container_name: graduation-nginx
    ports:
      - 80:80
    volumes:
      - ./nginx.conf:/etc/nginx/nginx.conf  # 映射配置文件
      # nginx与django的静态文件映射到宿主机的路径要一致
      - /usr/graduation/media:/media      # 映射到容器里面的/media    nginx.conf的访问路径要跟这个一样
      - /usr/graduation/static:/static    # 映射到容器里面的/static   nginx.conf的访问路径要跟这个一样
    depends_on:
      - django
