Back in October 2016, Docker released Infrakit, an open source toolkit for creating and managing declarative, self-healing infrastructure. This is the second in a two part series that dives more deeply into the internals of InfraKit. Introduction In the first installment of this two part series about the internals of InfraKit, we presented InfraKit’s design, architecture, and approach to high availability.  We also discussed how it can be combined with other systems to give distributed computing clusters self-healing and self-managing properties. In this installment, we present an example of leveraging Docker Engine in Swarm Mode to achieve high availability for InfraKit,…

With the introduction of swarm mode in Docker 1.12, we showed the world how simple it can be to provision a secure and fully-distributed Docker cluster on which to deploy highly available and scalable applications. The latest Docker 1.13 builds on and improves these capabilities with new features, such as secrets management. Continuing with the trend that simplicity is paramount to empowering individuals and teams to achieve their goals, today we are bringing swarm mode support to Docker Cloud, with a number of new cloud-enabled capabilities. All of this is in addition to the continuous integration (CI) features of Docker Cloud,…

Last Wednesday was Docker’s 50th meetup in San Francisco! There was an awesome turnout from the local Docker community to see Docker’s own Nishant Totla and Dongluo Chen and their talk on Swarm Mode. Nishant and Dongluo gave a talk entitled ‘Using Docker Swarm Mode and healthchecks to Deploy Applications Without Loss’ where they demonstrated how to do service upgrades without impacting your application.   They explained that Docker swarm mode enables users to manage their applications with service primitives and the healthcheck feature provides health indications for a container. Coming up in the Docker 1.13 release, Docker Swarm can connect healthcheck results with load balancers to…

In case you missed it, we launched Dockercast, the official Docker Podcast last month including all the DockerCon 2016 sessions available as podcast episodes. In this podcast, we meet Mano Marks, Director of Developer Relations at Docker.  Mano catches us up on a lot of the new cool things that are going on with Docker.  We get into the new Docker 1.12 engine/swarm built-in orchestration. We also talk about some cool stuff that is happening with Docker and Windows as well as Raspberry Pi and Docker. You can find the latest #Dockercast episodes on the Itunes Store or via the…

For this week’s Docker Online Meetup, Docker Captains Ajeet Singh Raina, Viktor Farcic and Bret Fisher shared their tips and tricks for built In Docker orchestration. Ajeet talked about the best ways to use Docker 1.12 Service Discovery and shared key takeaways. Viktor talked about best practices for setting a Swarm cluster and integrating it with HAProxy. Bret concluded the meetup with a presentation on Docker 1.12 command options and aliases including cli aliases for quick container management; the shortest path to secure production-ready swarm; how to use cli filters for easier management of larger swarms; and docker remote cli security setup.  …

For this week’s Docker Online Meetup, Sr. Director, Networking at Docker, Madhu Venugopal, joined us to talk about Docker 1.12 Networking and answer questions. Starting with Docker 1.12, Docker has added features to the core Docker Engine to make multi-host and multi-container orchestration simple to use and accessible to everyone. Docker 1.12 Networking plays a key role in enabling these orchestration features. In this online meetup, we learned all the new and exciting networking features introduced in Docker 1.12: Swarm-mode networking Routing Mesh Ingress and Internal Load-Balancing Service Discovery Encrypted Network Control-Plane and Data-Plane Multi-host networking without external KV-Store MACVLAN…

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…

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…
