当运行docker-compose up时我得到python：无法打开文件’manage.py’：[Errno 2]没有这样的文件或目录

这是我的Dockerfile：

FROM python:3.6.1

# set working directory
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

# add requirements (to leverage Docker cache)
ADD ./requirements.txt /usr/src/app/requirements.txt

# install requirements
RUN pip install -r requirements.txt

# add app
ADD . /usr/src/app

# run server
CMD python manage.py runserver -h 0.0.0.0

这是我的docker-compose.yml：

version: '2.1'

services:

  users-service:
    container_name: users-service
    build: .
    volumes:
      - .:/usr/src/app
    ports:
      - 5001:5000 # expose ports - HOST:CONTAINER

这是我的项目目录的结构(我运行我的docker命令)：

├── docker-compose.yml
├── Dockerfile
├── env
│   ├── bin
│   ├── include
│   ├── lib
│   ├── lib64 -> lib
│   ├── pip-selfcheck.json
│   ├── pyvenv.cfg
│   └── share
├── manage.py
├── project
│   ├── config.py
│   ├── __init__.py
│   └── __pycache__
└── requirements.txt

首先,我运行docker-compose构建并获得以下输出：

Building users-service
Step 1/7 : FROM python:3.6.1
 ---> 74145628c331
Step 2/7 : RUN mkdir -p /usr/src/app

Removing intermediate container 31ae97876314
Successfully built 42c79e68f692
Successfully tagged flaskmicroservicesusers_users-service:latest

然后我运行docker-compose up返回错误：

Recreating users-service
Attaching to users-service
users-service    | python: can't open file 'manage.py': [Errno 2] No such file or directory
users-service exited with code 2

我在这里缺少什么？

最佳答案 从docker-compose.yml中删除卷并再次构建.

version: '2.1'
services:
users-service:
  container_name: users-service
  build: .
  ports:
    - 5001:5000 # expose ports - HOST:CONTAINER

在ubuntu上有docer-compose的问题.它无法装入音量.而且我可以看到你想要装载.到/usr/src / app

您需要在更新代码后再次构建映像.
