docker_django | Django version 3.0.3, using settings 'backend.settings'

docker_django | Starting development server at http://127.0.0.1:8000/

docker_django | Quit the server with CONTROL-C.

当我连接到 http://127.0.0.1:8000/它显示了这一点

运行 docker-compose 命令没有问题/错误，但仅在访问站点时才出现。
我使用的是 ubuntu 19.10，该项目有 django v3。

Answer 1

您的应用程序仅监听来自 localhost 的请求，如果是容器，则是来自容器内部的请求。

试试这个撰写文件:

version: '3'

services:
    web:
        build: .
        container_name: docker_django
        command: python manage.py runserver 0.0.0.0:8000
        volumes:
            - .:/code
        ports:
            - "8000:8000"

按照建议更正端口号的拼写错误
