Docker运行找不到可执行文件“uwsgi”

Question

我正在尝试使用Docker部署猎鹰应用程序。这是我的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"]

但是我不断收到错误说：

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

我尝试在本地目录中运行uwsgi，它与命令配合得很好：

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

为什么Docker在这种情况下不工作？

这是日志，我很确定安装了uwsgi：

Answer 1

通常，您必须为可执行文件编写完整的修补程序。如果你去你的容器并运行这个命令whereis uwsgi它会告诉你它在/usr/local/bin/uwsgi所以你的CMD应该是相同的形式：

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

Answer 2

我在CMD中看到一些不正确的语法，请使用：

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

一些双引号是不正确的，--不是在wsgi-file之前。
