This will use a file called `Dockerfile.debug` for the build instructions
instead of `Dockerfile`.
```bash
$ curl example.com/remote/Dockerfile | docker build -f - .

a Dockerfile from stdin.
```bash
$ docker build -f dockerfiles/Dockerfile.debug -t myapp_debug .
$ docker build -f dockerfiles/Dockerfile.prod -t myapp_prod .
