    Before attempting to build Docker images, the DOCKER_HOST environment
    variable needs to be set to the local Docker client URL:
    Windows: set DOCKER_HOST=http://192.168.99.100:2376
    OS X Boot2Docker: export DOCKER_HOST=tcp://192.168.99.100:2376
    OS X Docker for Mac: http://localhost:2376
    To build a Docker image with Mule CE using, for example, the following command:
    mvn dockerfile:build -Pmule-3.8.1
