Q:
Get error while building a project in a docker container on windows 10
I'm trying to use boot2docker on windows 10.
I create a docker container as a standard user and try to build a python 3.5 django project in the container (with pipenv). I also created an ssh-key from my local computer. When I run my container with bash as a user, pip install packages successfully and I get a success message from pipenv. However, if I use powershell as the user, then pipenv fails to get packages. The errors I get are not very informative:

Is there anything that I should change in the Dockerfile? Or is this a problem with boot2docker?
A:
You might have to ensure you are starting your containers with command= instead of starting with bash:
docker run -itd --rm -p 3000:3000 --name some-php-demo -v "$PWD":/usr/src/app pypa/virtualenv /bin/bash -c "pip install -r requirements.txt && docker-php-ext-enable pdo_pgsql && ./usr/src/app/manage.py runserver 0.0.0.0:8000"
The /bin/bash -c "commands" need to be quoted as otherwise the shell will expand bash -c
Also you will have to set up your httpd to listen on port 80 (by default Apache is listening to 8080)
