Installing Docker for macOS

Docker wraps a micro Linux with the hypervisor framework to build a native application on macOS, which means we don't need third-party virtualization tools to use Docker on a Mac. To benefit from the hypervisor framework, you must upgrade your macOS to version 10.10.3 or more:

1. Download the Docker package and install it: https://download.docker.com/mac/stable/Docker.dmg.

1. You're now in Docker. Try creating and running your very first Docker container. Run the command with sudo if you're on Linux:

$ docker run alpine ls
bin dev etc home lib media mnt proc root run sbin srv sys tmp usr var

1. You'll see that you're under a root directory instead of your current one. Let's check the process list again:

$ docker run alpine ps aux
PID   USER     TIME  COMMAND
    1 root      0:00 ps aux

It's isolated, as expected. You're now all ready to work with the container.
