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.

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.

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.

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.

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.

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 they have something good to add.

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.

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.

Sentry is a realtime event logging and aggregation platform. At it’s core it specializes in monitoring errors and extracting all the information needed to do a proper post-mortum without any of the hassle of the standard user feedback loop. The main feature of sentry and the ability to send all of your application logs to one place, and then aggregate them, so that you only get one error email for the same error.
