Podcast Update

As many of you probably know, I launched a new podcast, called the Full Stack Journey Podcast, back in January. (Here’s the blog post announcing the new podcast.) In this post, I wanted to provide a quick update on the podcast.

Thoughts on Luminus Networks

Late last week, Cyrus Durgin from Luminus Networks published an article on SDx Central titled “The (R)evolution of Network Operations.” You may notice that my name is mentioned at the bottom of the article as someone who provided feedback. In this post, I’d like to share some thoughts—high-level and conceptual in nature—on network operations and Luminus Networks.

Using Terraform to Build an etcd2 Cluster on OpenStack

In this post I’ll build on my earlier introduction to Terraform to show a practical example of using Terraform to build a CoreOS-based etcd2 cluster on OpenStack. This information is based upon a demo that I created for a session at the Austin OpenStack Summit in late April, so all the files I reference in this post are available in the GitHub repo for that session.

Building a VMware-Formatted Cumulus VX Vagrant Box

In this post, I’m going to walk you through the process I used to build a Vagrant box for Cumulus VX that will work with VMware desktop hypervisors (like VMware Fusion or VMware Workstation). Although Cumulus Networks offers several different versions of Cumulus VX to download, they do not (strangely enough) offer a Vagrant box that will work with VMware’s desktop hypervisors.

There’s nothing terribly hard or unusual about this process, but I wanted to document it here for folks who might be new to the process (or who might be interested in why using this approach could be beneficial).

Prayer Time at the Austin Summit

A large portion of the OpenStack community is gathered in Austin this week for the Spring 2016 OpenStack Summit.

Technology Short Take #64

Welcome to Technology Short Take #64. Normally, I try to publish Short Takes on Friday, but this past Friday was April Fools’ Day. Given the propensity for “real” information to get lost among all the pranks, I decided to push this article back to today. Unlike most of what is published around April Fools’ Day, hopefully everything here is helpful, informative, and useful!

Docker Machine, OpenStack, and SSH Keys

I wanted to provide readers a quick “heads up” about some unexpected behavior regarding Docker Machine and OpenStack. It’s not a huge deal, but it could catch someone off-guard if they aren’t aware of what’s happening.
