Permission Denied with Docker-Compose on Windows

I am currently learning Docker, with the book "Using Docker". In chapter 5, the author switches from using docker run to using docker compose, which yields a permission denied error in my test application. Is there something I can do to have it work?

I use:

DockerFile:

FROM python:3.4

RUN groupadd -r uwsgi && useradd -r -g uwsgi uwsgi
RUN pip install Flask==0.10.1 uWSGI==2.0.8
WORKDIR /app
COPY app /app
COPY cmd.sh /

EXPOSE 9090 9191
USER uwsgi

CMD ["/cmd.sh"]

docker-compose.yml:

identidock:
  build: .
  ports:
    - "5000:5000"
  environment:
    ENV: DEV
  volumes:
    - ./app:/app

The application is located under C:/Users/MyUserName, as required by the Toolbox, to have shared volumes working correctly.

The working docker command, which starts the container and the web server, exposing it successfully to my Windows host:

docker run -e "ENV=DEV" -p 5000:5000 identidock

The docker-compose up command fails with the following message:

Starting identidock_identidock_1

ERROR: for identidock  Cannot start service identidock: oci runtime error: exec: "/cmd.sh": permission denied
←[31mERROR←[0m: Encountered errors while bringing up the project.

In my case I needed to run the command line (git bash) as administrator then run again :

docker-compose up -d .

this worked for me.

Try adding 

RUN chmod +x /cmd.sh

to your Dockerfile after 

COPY cmd.sh /

According to that issue it seems that the docker client sets the needed exec permission for the file while docker compose does not

It may be that the docker client sets the executable bit for all files, where as Compose does not (yet).
