docker_django |Django版本3.0.3，使用设置"backend.settings"

docker_django |在运行docker-compose命令没有问题/错误，只有在访问站点时才可以.

我正在使用ubuntu 19.10，并且该项目具有django v3.

Dockerfile

  FROM python:3ENV PYTHONUNFFERFERED 1运行mkdir/codeWORKDIR/代码复制 ./代码/RUN pip install -r requirements.txt 

docker-compose.yml

 版本:"3"服务:网络:建造: .container_name:docker_django命令:python manage.py runserver数量:- .:/代码端口:-"8000:8000"； 

解决方案

您的应用程序仅侦听来自本地主机的请求，如果是容器，则是来自容器内部的请求.

尝试此撰写文件:

 版本:"3"服务:网络:建造: .container_name:docker_django命令:python manage.py runserver 0.0.0.0:8000数量:- .:/代码端口:-"8000:8000" 

根据建议更正了端口号的错字

After running docker-compose up,

Starting docker_django ... done

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.

when i connect to http://127.0.0.1:8000/ it shows this There is no problem / error running the docker-compose command but only when visiting the site.

Im using ubuntu 19.10 and the project has django v3.

Dockerfile

FROM python:3

ENV PYTHONUNBUFFERED 1

RUN mkdir /code
WORKDIR /code

COPY . /code/

RUN pip install -r requirements.txt

docker-compose.yml

version: '3'

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

解决方案

Your application only listens to requests coming from localhost, which in case of a container are requests coming from inside the container.

Try this compose file:

version: '3'

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

corrected typo for port number as suggested
