Data-Driven RESTful API Testing for Java

This post is a Zombie that I'm resurrecting from my drafts. I"m not doing any Java these days, but hopefully this post might be useful to somebody

In my quest to get better code coverage for the OVSDB project in OpenDaylight I started to look at increasing coverage for the REST API. It's pretty difficult to test this in an efficient way (lines of code) and frameworks like Robot would have been easier to use. The disadvantage with using an external test framework is that code coverage (using a plugin like JaCoCo) would not be logged. Therefore I harnessed my Junit-Jitsu and found a solution that lives in the JVM

Taming Netlink

Netlink is a Linux Kernel interface that is used to talk Networking between Kernel processes, or from userland to Kernel processes. This post documents how I tamed Netlink and make working with it in Golang easier.

If you want to create an interface, set an MTU, set an IP address ...

Experimenting with Kernel-powered Open vSwitch and Docker

I've been thinking about running Docker on CoreOS and Project Atomic lately... While the deployment model would be pretty different to what we are used to, I have 50% of the work already done in docker-ovs so I was interested to see if my containers would work on a system with the Open vSwitch kernel module loaded...

Is SDN API directionality absurd?

I was finally catching up on a number of posts I'd saved to read later and noticed the prevalent use of "Northbound" and "Southbound". I'm now starting to question whether these terms are necessary or accurate.

Fun with Fig (and Docker)

I first heard of Fig when I read about Docker acquiring Orchard, a container hosting service, back in July. Last week I finally got to read a little more about it and it just so happens it is the missing piece of the puzzle in a couple of projects that I am working on right now!

Building a router with Open vSwitch

As part of my work in OpenDaylight, we are looking at creating a router using Open vSwitch... Why? Well OpenStack requires some limited L3 capabilities and we think that we can handle those in a distributed router.

Rolling back to Maven 3.0.X on OSX (Homebrew)

The current version of Maven in Homebrew at the time of writing is 3.2.2

This is great... unless one of the plugins in your project doesn't support it and then you have to downgrade :(

Fortunately it's not too painful

brew uninstall maven
brew tap homebrew/versions ...

Creating a Vagrant base box for RHEL with Bento

I <3 the Opscode Bento project. I use the Amazon S3 hosted images for pretty much all of my Vagrant boxes. When I started to use RHEL, I didn't want to make an exception... Fortunately Bento allows you to build your own RHEL, OSX or Windows boxes using Packer. This is how I built my RHEL 6.4 x64 box, but this process should work for any other box you want to build manually...
