The benefit for me would be quick, isolated development environments. I want to boot a contained swarm of services connected to each other in a single command, and shut them down in a single command as well
brew install docker docker-compose docker-machine
open https://kitematic.com/download/
Kitematic might even come with docker, docker-machine. It will then set up a docker machine for you and you're ready to go.For CLI, in Kitematic menu there is a button where you can install the binaries.
