I'm getting this message looping while the services are running.

I've done some digging.... NATS is not starting up from the docker file. The images build fine as far as I can see.

These are the containers running. 

λ docker container ls -a

api died as it can't connect to nats. HAHA!! found it..

I ran docker run -it --entrypoint /bin/sh aither_nats and the entrypoint script would not run.

then I ran vi entrypoingscript.sh and found ^M at the end of every line!

So... running from windows.. with GIT automatically changing the line endings... screws everything!

git config core.eol lf
git config core.autocrlf false
rm .git/index
git reset
git clean -f -d
git reset --hard
docker-compose down
docker-compose build
docker-compose up

and.... DONE!
