使用docker-compose的Dockerising Django应用出现问题 [英] Issue with Dockerising Django app using docker-compose

问题描述

我是Docker的新手，我想将Django应用作为容器进行dockerise。

I am new to Docker and I want to dockerise the Django app to run as a container. Followed as below.

这是 Dockerfile

FROM python:3
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
COPY requirements.txt /code/
RUN pip install -r requirements.txt
COPY . /code/

这是 docker-compose.yml conf

version: '3'

networks:
    mynetwork:
        driver: bridge

services:

  db:
    image: postgres
    ports:
      - "5432:5432"
    networks:
      - mynetwork
    environment:
      POSTGRES_USER: xxxxx
      POSTGRES_PASSWORD: xxxxx

  web:
    build: .
    networks:
      - mynetwork
    links:
      - db
    environment:
      SEQ_DB: cath_local
      SEQ_USER: xxxxx
      SEQ_PW: xxxxx
      PORT: 5432
      DATABASE_URL: postgres://xxxxx:xxxxx@db:5432/cath_local

    command: python manage.py runserver 0.0.0.0:8000

    volumes:
      - .:/code

    ports:
      - "8000:8000"

    depends_on:
      - db

在我的docker shell上，如果我从y运行ls命令，则指向Dockerfile目录路径，我看到manage.py文件，但是如果我运行：

well on my docker shell i point to Dockerfile directory, if i run an ls command from y path i see the manage.py file, but if i run:

docker-compose up

我收到此错误：

web_1 | python：无法打开文件'manage.py'：[错误2]没有这样的文件或目录
core_web_1以代码2退出

web_1 | python: can't open file 'manage.py': [Errno 2] No such file or directory core_web_1 exited with code 2

为什么我的应用程序找不到与 docker-compose up命令相同位置的manage.py文件？

Why my app don't find manage.py file that is in the same position as the "docker-compose up" command is?

PS：否我运行docker-compose命令时会创建/ code文件夹。

PS: No /code folder is created when i run docker-compose command. Is it correct?

非常感谢

推荐答案

尝试像这样编辑Dockerfile：

try to edit your Dockerfile like this:

FROM python:3
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
COPY requirements.txt /code/
RUN pip install -r requirements.txt
COPY . /code/
CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]

并删除命令：python manage.py runserver 0.0.0.0:8000 从撰写

我假设 manage.py 在 / code / 文件夹，因为在 dockerfile 中有 WORKDIR / code ，然后将在构建阶段，文件将被复制到其中

I assumed that the manage.py is in /code/ folder, since you have WORKDIR /code in the dockerfile then the server will be created in the build stage and the files will be copied to it
