Originally published at http://kencochrane.net/blog/2013/06/running-docker-on-digital-ocean/ 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 Ubuntu 12.04…

Hi everybody, Docker PPA 0.3.4 had been released, this time using our dockerbuilder code but without generating the binary package of docker.io. Basic QA had been done hoping the entire build process can be streamlined for the upcoming 0.4 release. Something to be aware, PPA for precise, quantal and raring use go 1.0.3 and the binary at docker.io use go 1.1. If you find any difference in behavior between them, don’t hesitate to let me know 🙂

Hi all, A couple of weeks ago, at the end of the docker hackday, I demo-ed dockerlite[1], a re-implementation of docker with posix shell scripts, and using BTRFS instead of AUFS for images and containers storage. Dockerlite proved itself to be an incredibly useful sandbox to test new concepts. The first result is the implementation of basic docker operations using BTRFS instead of AUFS. Instead of using AUFS layers, it uses BTRFS subvolumes and snapshots. It is very efficient (since it doesn’t have to perform copy-up like AUFS) and down the road should be a more viable option than AUFS.

Originally published at http://kencochrane.net/blog/2013/05/running-docker-on-rackspace-cloud/ 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 running since it has the most recent kernel, but the others aren’t…
