It seems like just yesterday that we were putting together the recap of Ansible's community growth in 2014. That was a very good year.
Here we are at the start of 2016 already -- and looking back on 2015, it was an even better year than 2014 was.
First, let's take a look at the numbers. For consistency's sake, we'll mostly compare to 2014 numbers, which can be found in last year's analysis. Note that the same caveats from last year's analysis also apply this year.
Debian Popcon
Debian’s Popularity Contest is an opt-in way for Debian users to share information about the software they’re running on their systems. Although it represents only a small sample of the Linux distro world, it’s useful because it’s one of the few places where we can really see an apples-to-apples comparison of install bases of the various tools. Because Ansible is agentless, we compare the Ansible package to the server packages of other configuration management tools.
For the first time in 2015, Ansible installations on this chart outnumbered Puppetmaster installations. Ansible shows continued strong growth, and appears to remain on an upward trend into 2016.
Caveats abound with this chart, but it does Continue reading

Containers as a Service (CaaS) as your new platform for application development and operations
Developers don’t adopt locked down platforms. That one simple statement summarizes decades of tension between IT operations and development teams. Along the spectrum of control versus agility are the desires and needs of IT operations teams responsible for keeping environments … ContinuedThree New Official Repos Join the Docker Library
We’re excited to announce that we’ve added three new Official Repos to the Docker Library. These repos are the latest additions to a growing library of curated content maintained by Docker and our partners. Docker users have pulled Official Repos … ContinuedDocker Online Meetup #31: Unikernels

Welcome to Technology Short Take #60. As usual, I’ve gathered what I hope to be a useful but varied collection of articles and links on key data center technologies. I hope something I’ve included here will be helpful—enjoy!
Networking
- The rise of Linux in importance in the networking industry continues, with Arista announcing enhancements to Arista EOS to support—among other things—Docker containers. (See this SDx Central article or this Network World article for more details.)
- As a partial counterpoint to the increased use/visibility of Linux in the networking industry, check out Ivan’s take on Dell’s OS10 announcement.
- And while we are on the topic of Linux and open source in the networking industry…read this entertaining and informative article on the importance of (truly) open source libraries in networking.
- NIC offloads can make a noticeable difference in performance with VXLAN-based overlay networks, so it’s worth some time making sure that VXLAN offloads are supported and enabled. Dale Coghlan has an article on the Broadcom bnx2x driver and VXLAN offload that may save you some time in this area.
- This post on automating NSX security rules using Splunk (and some custom code) is pretty cool. Granted, it’s a VMware post, so Continue reading
Andrey Sibiryov Reflects on Speaking at DockerCon EU 2015

He was also the lead developer of the Cocaine Cloud platform and led the Cloud Technologies department at Yandex in addition to working on the Helios CI/CD … ContinuedSpeaker Lineup for AnsibleFest London
Featuring speakers from Industrial Light and Magic, Atlassian, Cisco and more!
We're happy to share our speaker lineup for AnsibleFest London on Thursday, February 18th at InterContinental London - The O2. Our one-day user conference brings together hundreds of Ansible users, developers and industry partners to share best-practices, case studies and Ansible news.
With yet another record setting amount of submissions, our engineering team had their work cut out for them. We took each submission, anonymized them to remove any speaker/company/product information, and sent them off to our team of engineers for blind review. We then picked out a well-rounded agenda from the highest scoring talks.
Stay tuned for additional speakers announcements leading up to the event.
Deploying a Mesos Based Visual Effects Studio with Ansible
Aaron Carey, Production Engineer, Industrial Light and Magic
Jim Vanns, Senior Production Engineer, Industrial Light and Magic
Industrial Light and Magic is leveraging Ansible to deploy a Mesos cluster from scratch on multiple cloud platforms, build its application docker images and deploy them as services. This presentation will look at how ILM is using tags to manage services dynamically, and the steps taken to make it work across different cloud providers.

Webinar Q&A: Docker Networking
Many enterprises have moved from monolithic to microservices architectures, and are using Docker to help manage these services. With loosely coupled services existing in multiple containers, these containers must be able to communicate with one another, and sometimes even exist … ContinuedUsing Docker with macvlan Interfaces
In this post, I’m going to show you how to use macvlan interfaces with Docker for networking. The use of macvlan interfaces presents an interesting networking configuration for Docker containers that may (depending on your use case) address issues with the standard Linux bridge configuration.
Macvlan interfaces, if you’re unfamiliar with them, are a (somewhat) recent addition to the Linux kernel that enables users to add multiple MAC address-based logical interfaces to a single physical interface. These logical interfaces must reside in the same broadcast domain as the associated physical interface, which means that Docker containers attached to macvlan interfaces also will be in the same broadcast domain as the associated physical interface. In other words, the Docker containers will be on the same network as the host—no IPTables rules, no Linux bridge, just attached directly to the host’s network. This introduces some interesting possibilities (and potential challenges), but I’ll save that discussion for a future post.
Right now, macvlan supported is implemented via an unsupported Docker Network plugin hosted on GitHub. However, I suspect that the macvlan functionality found in this plugin will find its way into the core of Docker Network, and probably sooner rather than later.
You’ll Continue reading
