In this post, I’m going to walk you through the steps to install Ansible 2.x into a Python virtual environment (virtualenv) on OS X. 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).

A large portion of the OpenStack community is gathered in Austin this week for the Spring 2016 OpenStack Summit. As I’ve done at previous Summits (and other events), I’m offering to gather with other Christian believers for a brief time of prayer in the mornings before the sessions kick off each day.

Welcome to Technology Short Take #65! As usual, I gathered an odd collection of links and articles from around the web on key data center technologies and trends. I hope you find something useful!

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!

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.

Long-time readers know that my wife, Crystal, has been running this thing called Spousetivities for a few (OK, eight) years now. While Spousetivities originally started out as a VMworld thing, it rapidly expanded, and this year Spousetivities will be at a number of events. That includes the spring OpenStack Summit in Austin, TX!

In this post I’m going to share how to add some Git and Docker Machine “awareness” to your OS X Bash prompt. This isn’t anything new; these tricks are things that Bash users have been employing for years, especially on Linux. For most OS X users, though, I think these are tricks/tools that aren’t particularly well-known so I wanted to share them here.

In this post I’m going to talk about how to use Docker Machine to build a Docker Swarm cluster on Amazon Web Services (AWS). This post is an adaptation of this Docker documentation post that shows how to build a Swarm cluster using VirtualBox.

One of the projects that I started last year was my GitHub “learning-tools” repository, in which I store tools (of various sorts) to help with learning new technologies. Many of these tools are Vagrant environments, but some are sample templates for other tools like Terraform. I recently made some updates to a couple of the tools in this repo, so I wanted to briefly update my readers.

As part of a broader effort (see the post on my 2016 projects) to leverage public cloud resources more than I have in the past, some Docker Engine-related testing I’ve been conducting recently has been done using AWS EC2 instances instead of VMs in my home lab. Along the way, I’ve found Docker Machine to be quite a handy tool, and in this post I’ll share how to use Docker Machine with AWS.
