Docker Machine is a tool that lets you install Docker Engine on virtual hosts, and manage the hosts with docker-machine commands. You can use Machine to create Docker hosts on your local Mac or Windows box, on your company network, in your data center, or on cloud providers like Azure, AWS, or Digital Ocean.
Using docker-machine commands, you can start, inspect, stop, and restart a managed host, upgrade the Docker client and daemon, and configure a Docker client to talk to your host.
Why should I use it?
Docker Machine enables you to provision multiple remote Docker hosts on various flavors of Linux.
Additionally, Machine allows you to run Docker on older Mac or Windows systems, as described in the previous topic.
