First, we need to install Docker and Docker Compose.
Docker is built on top of Linux container. So, docker can’t run natively on OSX. It’s required a virtual machine for running in OSX. Thanks for Boot2Docker, it’s a Linux virtual machine made for running docker on OSX.
So, there is different between running docker on Linux and OSX.
When running docker on Linux, your machine is both the localhost and the Docker host.
