The [Vagrant Docker VM](https://github.com/webdevops/vagrant-docker-vm) (Ubuntu 16.04) is using [dinghy docker](https://github.com/codekitchen/dinghy) for providing an automatic and dynamic reverse proxy which makes easy to start multiple instances of the boilerplate.
You can also use [dinghy docker](https://github.com/codekitchen/dinghy) standalone if you don't need an full Linux environment.
