Docker run cannot find executable “uwsgi”

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"]

However I keep getting error saying:

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

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

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

Why is Docker not working in this case???

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

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"]


I see some incorrect syntax in CMD, please use this:

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

some double quotes are incorrect and -- is not before wsgi-file .
