In this post, I’m going to discuss some concepts behind managing your Amazon Web Services (AWS) infrastructure using Ansible. Ansible is a very popular tool for configuring operating system instances and software; using the concepts and examples provided in this post would allow you to expand your use of Ansible to include—when using AWS—the creation and deletion of the operating system instances themselves, as well as related infrastructure components (like security groups or other services).

I recently came across a bug in using VMware Photon OS with Vagrant, and so in this post I’m going to point out this bug and provide a workaround. The bug is, fortunately, pretty innocuous, and only affects Vagrant environments that configure additional network interfaces to Photon OS VMs. The workaround is equally easy, thankfully.

This is a liveblog of the day 2 general session at VMworld EMEA 2016 in Barcelona, Spain. I wasn’t able to write a liveblog of the day 1 session due to some scheduling/logistical conflicts, but managed to get things arranged for day 2 (well, most of it—I’ll have to cut this short so I can get to a customer meeting).

Welcome to Technology Short Take #72. Normally, I try to publish these on Fridays, but some personal travel prevented that this time around so I’m publishing on a Monday instead. Enough of that, though…bring on the content! As usual, here’s my random collection of links, articles, and thoughts about various data center technologies.

In this post, I’d like to share with you some techniques I used to build a triple-provider Vagrant environment—that is, a Vagrant environment that will work unmodified with multiple backend providers. In this case, it will work (mostly) unmodified with AWS, VirtualBox, and the VMware provider (tested with Fusion, but should work with Workstation as well). I know this may not seem like a big deal, but it marks something of a milestone for me.

One of the things I often tell people is, “Use the right tool for the job.” As technologists, we shouldn’t get so locked onto any one technology or product that we can’t see when other technologies or products might solve a particular problem more effectively. It’s for this reason that I recently made VirtualBox—not VMware Fusion—my primary virtualization provider for Vagrant environments.

In this post, I’m going to show you how to install a specific version of the Docker Engine package on Ubuntu. While working on a side project (one that will hopefully bear fruit soon), I found myself in need of installing a slightly older version of Docker Engine (1.11 instead of 1.12, to be specific). While this task isn’t hard, it also wasn’t clearly spelled out anywhere, and this post aims to help address that shortcoming.

If you’re going to be in Barcelona for either VMworld EMEA (running the week of October 17) or the fall 2016 OpenStack Summit (running the week of October 24), then I recommend you plan for your spouse/partner/girlfriend/boyfriend/whatever to join you for what I believe are some pretty spectacular Spousetivities.

In this post, I’d like to describe how to use Vagrant with AWS, as well as provide a brief description of why this combination of technologies may make sense for some use cases. In some respects, this post is similar to my posts on using Docker Machine with OpenStack and using Vagrant with OpenStack in that combining Vagrant with AWS creates another clean “provider/consumer” model that makes it easy for users to consume infrastructure.

This post is a follow-up on my earlier post on using an SSH bastion host. Since that article was published, I’ve gotten some additional information that I wanted to be sure to share with my readers. It’s possible that this additional information may not affect you, but I’ll allow you to make that determination based on your use case and your specific environment.
