Docker Built-in Orchestration Ready for Production: Docker 1.12 Goes GA

We wanted to thank everyone in the community for helping us achieve this great milestone of making Docker 1.12 generally available for production environments. Docker 1.12 adds the largest and most sophisticated set of features into a single release since the beginning of the Docker project. Dozens of engineers, both Docker employees and external contributors, have made substantial contributions to every aspect of 1.12 orchestration including core algorithms, integration into the Docker Engine, documentation and testing.

We’re very grateful to the community, which has helped us with feedback, bug reports and new ideas. We couldn’t have done it without the help in particular of the tens of thousands of Docker for Mac and Windows beta users who have been testing our 1.12 features since DockerCon in June. We’ve seen contributions ranging from bash tab completion to UX up-and-down votes that helped us understand what users want most. Compared to what we unveiled at DockerCon, we’ve ended up with significant improvements in the swarm node join workflow (it’s simpler), error reporting (easier to view), UX improvements (more logical), networking (fixed reliability issues) etc.

The core team also wanted to give a Continue reading

Spousetivities at VMworld 2016

Many of you have asked, and here’s the answer: Yes, there will be Spousetivities at VMworld 2016 in Las Vegas, NV! For those of you who may be new to the VMworld scene, Spousetivities started in 2008 when my wife got together with a small group of spouses and partners traveling with the conference attendees. From there, it’s become a staple of the VMworld community events. Read on for more details on what’s planned this year at VMworld 2016!

  • First up is the famous “Getting to Know You” breakfast, but with a slightly different approach. This year you’ll be cooking breakfast with Chef Phillip Dell, winner of season 9 of “Chopped”. How cool is that?
  • There will be a walking tour of the Las Vegas Strip, in case there are folks that are new to Vegas.
  • A trip to the Grand Canyon is available. If you haven’t yet been to the Grand Canyon, this is a great way to go—private bus, meals along the way, etc. Much easier than planning such a trip yourself!
  • Of course, you’ll have the opportunity to see the Hoover Dam and Lake Mead.
  • Here’s a new one: a 2-4 mile easy hike up Mount Continue reading

The 10 Most Common Questions IT Admins ask About Docker

CnNSmL1VMAAzTx9.jpgOver the past few months we have attended a string of industry tradeshow events, helping to teach the enterprise world about Docker. We were at HPE Discover, DockerCon, RedHat Summit and Cisco Live all within the past 6weeks! I had the pleasure of helping to represent Docker at each of these awesome events and got to speak with attendees about Docker for the enterprise.

Technology Short Take #69

Welcome to Technology Short Take #69! In this post, I’ve collected a variety of links related to major data center technology areas. This episode is a bit long; sorry about that!

Networking

  • Lindsay Hill recently noted that he’s been working to add support to netmiko for the Brocade ICX and MLXe, and is looking into support for VDX. Netmiko, if you haven’t heard, is a fantastic Python library that’s really useful when writing Python-based network automation scripts.
  • I mentioned a while back that I was taking a deeper look at MPLS (to which my colleague Bruce Davie—one of the creators of MPLS—jokingly quipped, “Why are you looking at legacy tech?”). Honestly, I haven’t had a great deal of time to make much progress, but I did come across this article by Sudeep Goyal which helped reinforce some of the basics I already knew. It may prove useful to others who are also seeking to improve their knowledge of MPLS.
  • Peter Phaal has been writing some really interesting stuff (interesting to me, at least). First up, there’s a great article on using IPVLAN with Docker and Cumulus Linux (with a tie back to sFlow, naturally!). I’m really eager to Continue reading

It all started with Dockerizing an old version of Confluence with Docker Datacenter

This is a guest post by Shawn Bower

Screen Shot 2016-07-21 at 10.41.29 AM

In my role as Cloud Architect I often hear, “Docker sounds great but it won’t work for my application.”  In my experience Docker can improve the state of many applications including legacy and vendor solutions.  The first production workload at Cornell on Docker was the University’s wiki which is run on Atlassian’s Confluence in April 2015.

Our installation of Confluence is an interesting intersection of legacy and vendor solution.  We have customized the code, to work with our single sign on solution, as well as a custom synchronization with LDAP for group management.  When we started the project to move Confluence to the cloud the infrastructure, the software was old, compiled from the source and was being hand maintained.

Indiana University Uses Docker Datacenter for Production-Ready Orchestration

Founded in 1820, Indiana University has over 115,000 undergraduate and graduate students, 20,000 faculty members and eight campuses located throughout the State of Indiana. The University’s vision is to provide their students with the best possible education experience via a world-class IT team.

For almost a decade the university was building custom scripts and deploying their applications onto VMs running on RHEL 6. A process that involved lots of manual work. In addition to this, their environment was optimized for their legacy Java-based applications.

In order to give their students the best experience possible, the University needed to not only modernize their 150 applications that span across both administrative and student lines and include everything from human resources based applications, course selection, finances and other student-facing applications. They also needed the ability to deploy their applications across their multi-host datacenter environment. They required a production-ready solution. A tool that would enable them to build new process around packaging, deployment, management, and scale for both centralized and de-centralized environments at the same time.

For this, Indiana University turned to the Docker Datacenter (DDC) solution. DDC is our commercial solution that delivers a Containers as a Service platform and includes: Universal Control Continue reading

Introducing Ansible Tower 3

The Best Way To Run Ansible In Your Organization Just Got Better

We’ve been hard at work since the last release of Tower, listening to community feedback and working to create the best possible experience for Tower users. We are pleased to introduce Ansible Tower 3, evolving from Ansible’s simple, powerful and agentless automation and extending that power to your team and organization.

Tower 3 boasts an entirely reworked UI that makes it simpler and easier to use Tower to automate your environments and share your automation. On top of that, we’ve equipped this newest edition of Tower with a host of new features to speed productivity and visibility within your Tower workflows, managing complex deployments and scaling the power of automation.

These features include: 

Expanded and Simplified Permissions

In prior releases of Tower, we operated on an implicit permissions system. For a user to be able to see, and run, a job, they needed permissions on not only the project that housed the Playbook, but also the inventory, and the credential used.

Now, with Tower 3, we’ve made things much simpler… if you have a job that you want a user or team to run, just give them Continue reading

Swarm Mode on a Raspberry Pi Cluster

Last week I sat down with Dieter Reuter from Hypriot. Dieter is a Docker Captain who spends a lot of time working with ARM and Raspberry Pis in particular. Dieter told me how excited he is by Swarm Mode in particular because of how easy it would be to set-up a collection of Internet of Things devices to work together securely.

So we took a look at how easy it is to set-up a Raspberry Pi cluster and run Docker 1.12 in Swarm Mode. Here’s how he ran Swarm Mode:

So if you want to set-up a cluster of your own, he’s provided this helpful guide with a bit more details on how to set-up a Raspberry Pi Cluster in 29 minutes.

Also a number of people have asked after the visualizer that he’s using in demo. This is a Node.js visualizer originally built by the Docker Cloud team for DockerCon Europe. I modded it for DockerCon in Seattle, and released the code in a GitHub repository. I welcome additional contributions.

Docker Datacenter @ DockerCon 2016: Image security, Engine 1.12 and Burning Man…

Interested in learning more about our plans for Docker in the Enterprise and getting involved in an upcoming Docker Datacenter beta? Let’s take a deeper look. On the second day of DockerCon, the keynote used different situations to discuss enterprise use of Docker. Our CEO Ben Golub broke down several fallacies in IT, CTO Keith Fulton of ADP painted a delicious picture of microservices as chicken nuggets, and Lily and I… well, we averted a massive security disaster and got our costumes ready for Burning Man.

Aside from shiny sequined jackets (not my normal wardrobe, I promise) and Ben’s enthusiastic “business guy” cameo, we presented a prototype of the next version of Docker Datacenter, our commercial solution for running containers-as-a-service (CaaS) in an on-premises or public cloud enterprise environment. Docker Datacenter is an integrated CaaS platform to securely ship, orchestrate and manage Dockerized apps and system resources. The sneak peek during the keynote shows a prototype UI and features. Some of the things you saw may change as we get to launch but what’s important are the capabilities we are bringing to the enterprise platform.

In the keynote presentation we demonstrated these enterprise use cases:
