Building Network Tools using Docker

Docker Build Text

I am going to start pushing out an app every month that fixes some problem in networking. In this case I hacked it up over the past couple of weekends, but other times it will just be me using someones open source awesomeness and demoing it. First some thoughts on where we are in the wild world of networking to …

Docker Command One Liners

Docker Logo

I love the code snippets, it’s how I learn any syntax by rolling up the sleeves, hacking and breaking while taking notes along the way. It’s probably not the most efficient but the muscle memory is how I learn. Here is a list of one liners from my notes in no particular order (even though I tried to in a …

Installing Golang IDE Support in Intellij

Docker Gopher Banner

I have always preferred Intellij Community Edition IDE for Java, Bash, Python, Node and anything else I have needed, including recently C/C++ which is pretty slick. The plus is I can hang on to key-mappings, syntax color and general workflow all in a ubiquitous dev environment. There are some good IDE options for Go and of course support for the …

Golang for Network Ops

Golang Gopher

I get asked quite often where the traditional network engineer / network ops should start if they want to broaden their horizons with better code hacking skills or they have spent the last 20 years using Perl scripts or more recently Python and need a change. The answer is easy, Golang. At Socketplane, we all ditched the past couple of …

The following is a walk through of the OVSDB project within OpenDaylight for OpenStack integration. There are a couple of bugs so it is not for the faint of heart. It is intended for those looking to get their development environment up and running. We will have videos and what not walking through the installation and code reviews of the …

Getting Started With OVSDB

Open Source

OVSDB (Open vSwtich Database) is a management protocol used to manipulate the configuration of Open vSwitches and more recently vendors have begun implementing OVSDB in their Ethernet switches firmware. Some of those vendor data plane implementations are already running OVS under the hood so the implementation should be relatively painless. A project I am involved in developing is the OVSDB …

OpenDaylight Maven and OSGI Dev Notes

Osgi Maven

Prior to OpenDaylight I had only used the ODGI framework with David Ericson’s Beacon contorller. I wanted to dump some of my notes from code hacking over the past couple of weeks. Most of the time has been spent getting used to OSGI and Maven. After the Maven and OSGI overviews, I list my dev notes for setting OSGI log …
