Step 2: Install Docker and boot2docker You have two choices: the offical package from.

Ran it, and made it through to the end of the installer: Opened VirtualBox and confirmed default is runnin.

Have you heard of You probably haveeverybodys talking about it.

Even my dads like, whats Docker I saw someone twitter about it on the Facebook.

Docker is a program that makes running and managing super easy.

It has the potential to change all aspects of server-side applications, from development and testing to deployment and scaling.

Its a top notch book and I highly recommend it, but Ive had some problems running the examples on OS X.

After a certain point, the book assumes youre using Linux and skips some of the extra configuration required to make the examples work on OS X.

This isnt the books fault; rather, it speaks to underlying issues with how Docker works on OS X.

This post is a walkthrough of the issues youll face running Docker on OS X and the workarounds to deal with them.

Its not meant to be a tutorial on Docker itself, but I encourage you to follow along and type in all the commands.

Youll get a better understanding of how Docker works in general and on OS X specifically.

First, lets talk about how Docker works and why running it on OS X no work so good.

The Docker server is a daemon that does all the heavy lifting: building and downloading images, starting and stopping containers, and the like.

The Docker client is a command line program that communicates with the Docker server using the REST API.

You will interact with Docker by using the client to send commands to the server.

The machine running the Docker server is called the Docker host.

The host can be any machineyour laptop, a server in the Cloud, etcbut, because Docker uses features only available to Linux, that machine must be running Linux (more specifically, the Linux kernel).

Docker on Linux Suppose we want to run containers directly on our Linux laptop.

It doesnt have the kernel features required to run Docker containers natively.

Boot2docker is a lightweight Linux distribution made specifically to run Docker containers.

Heres a diagram of how well use boot2docker: Docking on OS X Well run the Docker client natively on OS X, but the Docker server will run inside our boot2docker VM.
