Run container on Docker Machine

Execute docker command on Docker Machine

If you run a docker command while DockerMachine is active, you are running the command on the host of the active DockerMachine. The following is running an nginx container on the active test-box, a Docker Machine host. After execution, when you access port number 8000 of the IP address of the test-box host from a browser (192.168.99.110: 8000), the "Welcome to nginx!" Screen is displayed.

$ docker-machine ls
NAME          ACTIVE   DRIVER       STATE     URL                         SWARM                DOCKER      ERRORS
