Script env.sh reads config.yaml, so you don't need to update this script if you want to change something or to add new Docker image. Usage info:
Insted of building images on your machine you can get them from trusted image repository on public docker index: https://index.docker.io/u/komljen/
This command will search for dependencies (wp.links) and start them first if they are present. Then it will run new container which will be linked to dependencies. Also it will read port (wp.service.port) and name (wp.service.name).
