There are two options for creating VM machines with Docker installed:

1. Deploying a Linux VM to run single-server development environment using docker-machine (Recommended for development environments)
2. Deploying a Linux VM or Windows Server 2016 to run a single-server development environment using ARM template (Recommended for creating testing environments)

If you want to create a VM for deploying images you build locally, then use the first option.

If you want to create a VM to run images deployed to DockerHub (to provide some test environment) then use the second option.
