Docker运行无法找到可执行文件"uwsgi". [英] Docker run cannot find executable "uwsgi"

问题描述

我正在尝试与Docker一起部署falcon应用程序.这是我的Dockerfile:

I am trying to deploy a falcon app with Docker. Here is my Dockerfile:

FROM python:2-onbuild

# Set the working directory to /app
WORKDIR /app

# Copy the current directory contents into the container at /app
ADD . /app

RUN pip install -r ./requirements.txt
RUN pip install uwsgi

EXPOSE 8000

CMD ["uwsgi", "--http", " :8000" , "—wsgi-file", "falconapp.wsgi"]

但是我总是收到错误消息:

However I keep getting error saying:

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

我已经尝试在本地目录中运行uwsgi，并且与以下命令配合使用效果很好:

I've tried running uwsgi in the local directory and it works well with the command:

uwsgi --http :8000 --wsgi-file falconapp.wsgi

在这种情况下，为什么Docker不起作用???

Why is Docker not working in this case???

这是日志，我很确定已安装uwsgi:

Here is the log, I'm pretty sure uwsgi is installed:

推荐答案

很多时候，您必须为可执行文件编写完整的补丁程序.如果转到容器并运行此命令whereis uwsgi，它将告诉您它位于/usr/local/bin/uwsgi，因此您的CMD应该采用相同的格式:

very often you have to write the full patch for the executable. If you go to your container and run this command whereis uwsgi it will tell you it is at /usr/local/bin/uwsgi so your CMD should be in the same form:

CMD ["/usr/local/bin/uwsgi", "--http", " :8000" , "--wsgi-file", "falconapp.wsgi"]
