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)
