Running app via Docker on Mac fails to launch

[awhittle3]

Issue

I tried running the app on Mac using the provided Docker instructions:

# git clone and cd to repo directory
docker build -t hmm .
docker run --rm -it -v $(pwd):/app/ -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY hmm

I got the following error and the app failed to launch:

env: 'php\r': No such file or directory
env: use -[v]S to pass options in shebang lines

Workaround

I think this issue is due to Windows line endings (\r) being committed to the repo. These steps worked for me to address the issue locally:

brew install dos2unix
find . -type f -exec dos2unix {} \;
# run docker run as usual

This could be addressed on a project level by adding .gitattributes.

Thanks. If you or anyone else can create a pull request with the necessary changes, it would be nice. I have no idea how Docker works.
