And the winners of Docker Global Hack Day #3 are…
The quality of the Docker hacks and amount of participation from the Docker community was simply phenomenal! Over 2,000 community members attended events around the world and 50 meetup groups organized local editions of this Docker Hack Day #3. Kudos to the Docker community and … ContinuedDockerCon EU 2015: Hands-On Labs
We know how busy everyone gets at DockerCon – there’s so much to do between conference talks, meeting members of the community and chatting with sponsors! We took all of the feedback from our pilot Docker Tutorials at DockerCon 2015 … ContinuedUsing Vagrant with OpenStack
In my earlier post on using Docker Machine with OpenStack, I talked about combining technologies in a “provider/consumer” model. In this post, I’m going to talk about creating this provider/consumer model using a different combination of technologies: OpenStack as the infrastructure provider and Vagrant for consuming that infrastructure.
If you’re unfamiliar with Vagrant, I recommend you first read this introduction to Vagrant (after that you can dig into all the other Vagrant-tagged posts). As I explain in that first post, Vagrant leverages the idea of providers (which enable Vagrant to work with various back-end virtualization platforms/solutions) as well as boxes (which are essentially VM templates). In this particular case, we’re leveraging an OpenStack provider for Vagrant that allows Vagrant to use OpenStack as the back-end virtualization solution. However, since OpenStack already has the equivalent of VM templates (in the form of images), there’s no need to use a Vagrant box. This makes using Vagrant with OpenStack slightly different than your typical Vagrant use case.
Prerequisites
Let’s start with reviewing some prerequisites—these are the things you’ll need to do/have done before you can use Vagrant with OpenStack (besides the obvious things like having Vagrant installed).
- You’ll need a working OpenStack Continue reading

DockerCon Europe CFP summary and 2nd round of Black Belt speakers!
The CFP for DockerCon Europe 2015 closed last week, and we were blown away by the quantity and quality of the submissions. Thank you to the 303 individuals who submitted talks – it’s going to be mighty difficult for the DockerCon Committee … ContinuedA Quick Reference to Adding New Storage with LVM
This post walks through the process of adding storage capacity to a Linux server using LVM. There’s nothing new, revolutionary, or cutting-edge about this post—honestly, it’s really more for my own reference than anything else. Adding logical volumes is something that I do so infrequently that it’s hard to remember all the commands, so I’m recording them here for when I need them next time.
First, list the physical disks in the system (all commands should be prefaced with sudo or run as a user with the appropriate permissions):
fdisk -l
This will help you identify which (new) disk needs to be added. In my examples, I’ll use /dev/sdb.
Start partitioning the new disk (replace /dev/sdb with the appropriate values for your system):
fdisk /dev/sdb
I’m assuming that this isn’t a boot drive and that whatever logical volumes you create will take up the entire disk. Once you get into fdisk, follow these steps:
- Enter
nto create a new partition. - Enter
pto make this a primary partition. - Enter
1to make this the first partition on the disk. - Press enter twice to accept default start and end cylinders (unless you know you need to change them).
- Enter

Using Docker Machine with OpenStack
In this post, I’m going to show you how to use Docker Machine with OpenStack. This is something I’ve been interested in testing for a while, and now that I finally have my test lab back up and running, I was able to spend some time on this. I’ll spend some time later in the post covering my reasons for wanting to look at this, but I’ll start with the technical content of how it works.
I tested this setup with the following components:
- The client system was running OS X 10.9.5 with the Docker 1.8.2 client binary and Docker Machine 0.4.1.
- The OpenStack cloud was running the Juno release on Ubuntu 14.04 LTS, KVM hypervisors, and VMware NSX for networking.
There are (at least) two approaches to using Docker Machine and OpenStack together:
- You can use Docker Machine’s
genericdriver to consume already-provisioned OpenStack instances. This is, in large part, very similar to what I covered here, but I’ll cover it in this post just for the sake of completeness. - You can use Docker Machine’s
openstackdriver to automatically provision and configure new instances on an OpenStack cloud. This is the Continue reading
Tower 2.3 Has Arrived
We’re happy to announce the release of Ansible Tower 2.3, our console and service that brings control, security, and delegation to your Ansible deployments.
Historically Tower has been installed with a simple setup playbook that you run with the Ansible you already have to download and install Tower. But not everyone has the luxury of access to the internet at all times.
Starting with Tower 2.3, we now offer a bundled installer for Red Hat Enterprise Linux and CentOS systems. This all-in-one installer contains everything you need to get Tower started in one bundle, including bootstrapping of Ansible for you as needed. All you need is a Red Hat or CentOS machine with access to the vendor OS repositories - no other external access required. The playbook installer is still available as well, and Tower is also still available via Vagrant image or AMI if you’d prefer to try it via that method.
As usual, this release of Tower includes a variety of bug fixes as well, including performance improvements around listing jobs and job templates.
For more information on Tower 2.3, check the release notes at: http://docs.ansible.com/ansible-tower/latest/html/installandreference/release_notes.html

Technology Short Take #54
Welcome to Technology Short Take #54! In this episode, I’ve gathered an odd collection of links and articles about key data center technologies. Without further ado, let’s get to the content.
Networking
- Not sure if this link belongs in Networking or in Virtualization, but we’ll stick it here since it talks about VMware NSX. Here’s a three-part series on running VMware NSX on vSphere on AWS via Ravello Systems (part 1, part 2, and part 3). This is a great way to get your feet wet with NSX without having to invest in a home lab.
- This is a bit of an older post, but I really appreciated Bob McCouch’s post on building tools versus “programming.” I think Bob really hit the nail on the head when he said that the real goal is working efficiently with high quality and low error rates. If this means you need to learn to write a script, then so be it. If it means it needs to be manual, then so be it (but please, please, do take the time to document it!).
- Dan Conde of ESG has a write-up on the role of NSX in Continue reading

Many of the questions we frequently get are related to deploying applications and stacks into Amazon Web Services. Back in July, Ansible Government teamed up with partner DLT Solutions to host a webcast demonstrating the creation of a Red Hat stack in AWS entirely managed with Ansible. Watch it now and continue reading below for more information.
IT organizations look toward AWS for a number of reasons, but according to IDC, deploying applications in AWS results in a 64% lower TCO and 82% less downtime. Now let’s be honest. Who doesn’t like less downtime?
Red Hat is the leading Open Source provider for infrastructure and middleware solutions. Their industry-standard Red Hat Enterprise Linux and JBoss middleware are widely deployed in on-prem physical and virtual environments, and are the benchmark for stability, security, and performance.
But how can you leverage that power in AWS? With Ansible, it’s easy.
In the webcast, we demonstrate the deployment of a complete JAVA-based web application, including RHEL, JBOSS, and a load balancer. Once installed, we demonstrated how to use the same playbook that deployed the application to update the application. Better yet, these examples are available for you to start using and experimenting with today.
Here’s Continue reading
