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 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 Continue reading…

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 a future 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 Continue reading…

Docker 1.12: Now with Built-in Orchestration!

Three years ago, Docker made an esoteric Linux kernel technology called containerization simple and accessible to everyone. Today, we are doing the same for container orchestration. Container orchestration is what is needed to transition from deploying containers individually on a single host, to deploying complex multi-container apps on many machines. It requires a distributed platform, independent from infrastructure, that stays online through the entire lifetime of your application, surviving hardware failure and software updates. Orchestration is at the same stage today as containerization was 3 years ago. There are two options: either you need an army of technology experts to cobble together a complex ad hoc system, or you have to rely on a company with a lot of experts to take care of everything for you as long as you buy all hardware, services, support, software from them. There is a word for Continue reading…

Biogen: Data Science and Docker Swarm

written by Theo Platt, Associate Director, Biogen and Karl Gutwin, Senior Data Architect, Biogen The Data Sciences department at Biogen has been using Docker and watching the (r)evolution for a couple of years. Last year, as our experience with Docker grew and the use cases expanded, we built our own early Docker Swarm cluster with homegrown orchestration capabilities. Through cutting-edge science and medicine, Biogen discovers, develops and delivers worldwide innovative therapies for people living with serious neurological, autoimmune and rare diseases. Founded in 1978, Biogen is one of the world’s oldest independent biotechnology companies and patients worldwide benefit from its leading multiple sclerosis and innovative hemophilia therapies.

#SwarmWeek: It’s a Wrap – Thanks Y’all!

Thank You. Wow what a week! When we first brainstormed Swarm Week, it was to help spread awareness of Docker Swarm to the community. What we did not anticipate was the tremendous support from the community to proactively share your knowledge, experiences and experiments with each other so publicly. We had a lot of fun starting new conversations and learning about what people are doing with Swarm. Our hope is that this week inspires you to try something new and push your Swarm to the limit. If you missed any part of Swarm Week, here is the recap of some useful tutorials, case studies and articles designed to enhance your knowledge of Docker Swarm.

[#SwarmWeek Edition] Docker Online Meetup #35: Docker Swarm

As part of #SwarmWeek, we hosted a Docker Online Meetup all about Docker Swarm. Docker Swarm is native clustering for Docker. It turns a pool of Docker hosts into a single, virtual Docker host. Because Docker Swarm serves the standard Docker API, any tool that already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts. Victor Vieux, a Software Engineer working on the Swarm product, presented an overview of Swarm along with a demo and Jeff Nickoloff, author of “Docker in Action”, reviewed his findings from scaling Swarm and Kubernetes. Below are the recorded video and slides from the Docker Online Meetup.

#SwarmWeek: Realtime Cluster Monitoring with Docker Swarm and Riemann

Lately I’ve become fascinated with Riemann, a piece of software written in Clojure for the purpose of supervising the health of distributed systems. Created by Kyle Kingsbury (a.k.a. aphyr) of Jepsen fame, Riemann is a powerful tool for montioring, processing, and responding to information from your cattle herd.
