The Docker Guidebook

1   Introduction

The goal of this guidebook is to introduce you to Docker, show you what it can do, and how to get it up and running on your system, and how to use it to make your life better.

This guide is still very rough, and needs a lot of work, but because it is open source and available on github.com you can help make it better. If you would like to add to it or fix something, please fork it and submit a pull request.

One of the goals of this project is to make it available ...

Running Docker on Digital Ocean with Ubuntu

I recently wrote a post on how to get Docker up and running on Rackspace and since then I have received some requests on how to get it up and running on other hosts. One of those hosts is Digital Ocean a hot new Cloud hosting provider that offers a 512MB 20GB SSD VPS for only $5.00 / month. A really great deal, and also a great price if you want to play around with some new tool and not have to worry about possibly breaking a production server. This post should guide you though the process of getting an ...

Getting Docker up and running on a RaspberryPi

This year I attended PyCon US and I was lucky enough to get a FREE RaspberryPi. At the same conference dotCloud (The company I work for), was giving a lightning talk for a project that we have been working on, called Docker. Docker is a tool that allows you to better manage your Linux Containers (LXC). Shortly after I got the RaspberryPi, I started wondering if it would be possible to run Docker on it.

I did some digging and technically speaking the Pi should be able to run Docker, it satisfies all of the requirements.

  • LXC
  • AUFS

Upgrading the Ubuntu linux kernel on Rackspace cloud

Yesterday I wrote a blog post on how to install Docker on to RackSpace Cloud, and one of the steps was to upgrade the kernel to the lastest one so that Docker would be nice and stable. The problem that I found out was that there wasn't much information how to upgrade the kernel on the Rackspace Cloud servers, so I thought I would put the steps here.

The goal here is to upgrade Ubuntu 12.04 and 12.10 so that it has the same kernel as 13.04. Here are the steps.

Ubuntu 12.04

  1. Build an ...

Running Docker on Rackspace with Ubuntu

I have been playing with Docker a lot lately, and it got me wondering how hard it would be to run Docker on the different Cloud providers. I noticed there were already directions on how to install on Amazon EC2 but nothing for the Rackspace Cloud.

If you would like to run Docker on the RackSpace Cloud using Ubuntu you're in luck. I just spent the afternoon figuring out how to get it installed on Ubuntu 12.04, 12.10, and 13.04, and I have included my notes below. 13.04 is the easiest to get up and ...

Intro to Python and Django Presentation

I recently gave a talk at a DjangoMaine meetup introducing folks to Python and Django. There wasn't enough time to go over everything, so I tried to pick and choose the parts that I felt where important to go over, in order to have a good overview of what Python and Django is all about.

I hope this was useful to the folks that attended. If so, it would be really helpful to know what parts you would like to know more about. Then we can have some follow up talks doing a deeper dive into those select topics ...

New Pelican Based Blog

I have recently changed my Django based blog to a statically generated blog based on Pelican, and hosted by GitHub Pages. This is for a couple of reasons.

The first reason was because my blog is really simple, it was just a bunch of reStructuredText documents that were converted to HTML. I didn't need the Django-admin features and I always felt it was a little overkill for my blog.

The second reason was because I wanted to host my blog contents on GitHub so that others could change/update/edit my blog posts and send me pull requests if ...

Deploying my Django application to dotCloud: Part 2

As I mentioned in a recent blog post, in the 11 months since I wrote my first post on dotCloud, I now work there. Besides me working there, there has been a lot of other changes at dotCloud, and I wanted to take the time to update my original post so that it was up to date and had all the recent information. I'm going to completely rewrite the old blog post here, with updated information, and leave the old one around for posterity.

dotCloud's goal is to provide a bunch of different independent services that you can ...

I'm now working for dotCloud

A lot has happened in the 11 months since I wrote my first blog article on dotCloud. There was an Egyptian revolution, a royal wedding, a new iPhone and iPad, Osama bin Laden was killed, and on a more personal note, I left my job at CashStar and I now work for dotCloud. In the grand scheme of things, my job change was nothing compared to those big events of the past 11 months, but it was pretty big for me.

I had worked for CashStar.com for over 3.5 years, and I was there from pretty much the ...
