Using Vagrant and Docker Machine Together
In this post, I’m going to show you a quick tip I used today to combine the power of Vagrant with that of Docker Machine to quickly and easily create Docker-enabled virtual machines (VMs) on your laptop. This could be useful in a variety of scenarios; I leave it as an exercise for the reader to determine the best way to leverage this functionality in his or her own environment.
In my case, I needed to be able to easily create/destroy/recreate a couple of Docker-enabled VMs for a project on which I’m working. The problem I faced was that the tools I would normally use for such a task—Vagrant and Docker Machine—each had problems when used on their own:
- Vagrant has a Docker provisioner, but I could only get it to install the latest released version of Docker. In my case, I needed to run a test version (specifically, the RC2 build of Docker 1.8.0).
- Docker Machine has various back-end drivers that can create VMs into which Docker is provisioned, but the VMware Fusion driver for Machine only works with Boot2Docker. In my case, I needed to run Ubuntu 14.04 in the VMs.

System Tracking
This is not a generic “Postgres vs. MongoDB” performance post. This post details the process of comparing Postgres vs. MongoDB with a particular use case in mind, System Tracking.
Desirable Databases Features
Postgres is a candidate database since it is already in use by Tower. MongoDB is the other database considered for an in depth analysis for many reasons including: (1) document store of the JSON structure, (2) arbitrary structure query support, (3) and the ability to run on a single machine and later scale.
Comparing the two databases begins with identifying our System Tracking requirements. What is System Tracking?
For Tower, System Tracking is time based snapshots of machine facts. Facts are key value pairs of system state. The inspiration comes from the open source Ansible. Ansible facts will be supported in System Tracking along with 3 other fact types: packages (i.e. rpm or apt-get), services (i.e. mongodb, apache2), and files (i.e. /var/log/message). We support these 3 facts as fact modules. We also want to allow for customer built modules. Facts generated by the 4 core modules plus user created modules would be stored in Tower’s System Tracking database; allowing customers to take advantage Continue reading

While prior versions of the Ansible Tower documentation focused on a single PDF, we've gone in a different direction for this release. You will still have all of the great content available from earlier releases, but in a documentation set comprised of guides focused on getting you going, installation and reference, administration, and more. I have to say that all of the outstanding documentation that was created for prior versions gave me a strong foundation to work with for this release and I'm grateful for the hard work put in before I joined the Ansible team.
With Ansible Tower 2.2, we are ensuring that access to HTML as well as PDF versions of the Tower documents are easily available from the docs website. Our Ansible Tower HTML documents also look and feel more similar to the Ansible documentation available online that you've come to know and love. And, they've been indexed to help you find the information you need as quickly as possible.
First, we're introducing Ansible Tower to new users with our Quick Installation and Quick Setup Guides. These manuals are geared toward getting Ansible Tower installed and setup to the point of running a simple playbook. They Continue reading
Tower 2.2 is Here
We’re happy to announce that Ansible Tower 2.2 is now available.
Ansible Tower is the console and service that builds on the solid foundation of Ansible’s simple automation to bring the control, security, and delegation you need to spread automation across your IT infrastructure. We’ve worked hard to update Tower to bring new capabilities to our users. I’ve talked about these some when I discussed how Tower 2.2 was coming soon - now I’d like to go into a little more detail.
Refreshed UI with Setup Mode
We’ve talked to many of our customers who use Tower on an everyday basis. And the continuing refrain is:
“Foreground the stuff we need every day. Background what we don’t.”
We’ve started that process with Tower 2.2. First, you’ll notice the changes on the dashboard, where we’ve removed extraneous graphs so you can concentrate on the important information - are your hosts OK, and are your jobs succeeding. Plus, you’ll see lists of both recent completed jobs, and recently used playbooks.
We’ve also added sparklines to the display of job templates so that wherever you’re seeing your job templates, you have an easy visual display of how that job Continue reading
