[SOLVED] Container command not found or does not exist error with Docker

Hello folks,

I'm trying to migrate my docker image from Ubuntu to Alpine. Everything builds fine, but when the time to run the /start.sh script comes, it fails.

The Dockerfile is here. I believe the problem lies in the CMD line, but I'm not sure.

If I try to run it :
docker run test/alpine
I get :
exec: "/bin/sh /start.sh": stat /bin/sh /start.sh: no such file or directory
docker: Error response from daemon: Container command not found or does not exist..

Of course /start.sh is here and executable. If I do :
docker run test/alpine sh
And then (inside the container):
/bin/sh /start.sh
It works.

Has anyone have an idea on why I get this error ?

Thanks for reading :)

Regards,
~G

EDIT: after discussing with folks on the IRC channel, changing the CMD to /start.sh && exec /usr/bin/supervisord -c /etc/supervisord.conf -n works if I do a "docker run test/alpine". But starting it with docker-compose still fails with the same error...

EDIT2: ok it works now, had to change "build: ." to "image test/alpine" in .yml file \o/
