Is this a replacement for #1468?

[FedeG]

yes, and add more improvements

@FedeG should it still be possible to execute a shell on the development image such as with:
docker exec -it /bin/bash meanjs ?
I'm getting an EOF error which I didn't before.

[FedeG]

@lirantal The command docker exec -it /bin/bash meanjs is invalid docker command, the correct command is docker exec -it meanjs /bin/bash
Docker exec sintax: docker exec -it <container_in_runtime> <command>

[FedeG]

@lirantal When you send invalid container name to docker exec, the exec command returned EOF.
In your command, "/bin/bash" is the name of container and docker don't find this container.

Silly me, thanks for clearing out the confusion. Was on auto-pilot.
