Docker 镜像错误:“/bin/sh: 1: [python,: not found"

问题描述

我正在基于标准 Ubuntu 14.04 映像构建一个新的 Docker 映像.

I'm building a new Docker image based on the standard Ubuntu 14.04 image.

这是我的 Dockerfile:

FROM ubuntu:14.04
RUN apt-get update -y
RUN apt-get install -y nginx git python-setuptools python-dev
RUN easy_install pip
ADD . /code
WORKDIR /code
RUN pip install -r requirements.txt # only 'django' for now
ENV projectname myproject
EXPOSE 80 8000
WORKDIR ${projectname}
CMD ['python', 'manage.py', 'runserver', '0.0.0.0:80']

当我尝试运行此映像时，我收到此错误...

When I try to run this image, I get this error...

/bin/sh: 1: [python,: 未找到

/bin/sh: 1: [python,: not found

但是如果我在运行图像时打开一个 shell，运行 python 会按预期打开交互式提示.

But if I open a shell when running the image, running python opens the interactive prompt as expected.

为什么我不能通过Dockerfile中的CMD调用python?

Why can't I invoke python through CMD in the Dockerfile?

推荐答案

在 CMD 中使用 " 而不是 '.(文档)

Use " instead of ' in CMD. (Documentation)
