Get involved with the Moby Project by attending upcoming Moby Summits!

Last month at DockerCon, we introduced the Moby Project: an open-source project sponsored by Docker to advance the software containerization movement. The idea behind the project is to help the ecosystem take containers mainstream by providing a library of components, a framework for assembling them into custom container-based systems and a place for all container enthusiasts to experiment and exchange ideas. Going forward, Docker will be assembled using Moby, see Moby and Docker or the diagram below for more details. Moby Summit at DockerCon 2017 Knowing that that a good number of maintainers, contributors and advanced Docker users would be attending DockerCon, we decided to organize the first Moby Summit in collaboration with the Cloud Native Computing Foundation (CNCF). The summit was a small collaborative event for container hackers who are actively maintaining, contributing or generally involved or interested in the design and Continue reading…

InfraKit and Docker Swarm Mode: A Fault-Tolerant and Self-Healing Cluster

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, which in turn enhances the Docker Swarm cluster by making it self-healing.   Docker Swarm Mode and InfraKit One of the key architectural features of Docker in Swarm Mode is the manager quorum powered by SwarmKit.  The manager quorum stores Continue reading…

InfraKit Under the Hood: High Availability

Back in October, Docker released Infrakit, an open source toolkit for creating and managing declarative, self-healing infrastructure. This is the first in a two part series that dives more deeply into the internals of InfraKit. Introduction At Docker,  our mission to build tools of mass innovation constantly challenges to look at ways to improve the way developers and operators work. Docker Engine with integrated orchestration via Swarm mode have greatly simplified and improved efficiency in application deployment and management of microservices. Going a level deeper, we asked ourselves if we could improve the lives of operators by making tools to simplify and automate orchestration of infrastructure resources. This led us to open source InfraKit, as set of building blocks for creating self-healing and self-managing systems. There are articles and tutorials (such as this, and this) to help you get acquainted with InfraKit. Continue reading…

Docker Online Meetup #46: Introduction to InfraKit

In case you missed it, Solomon Hykes (Docker Founder and CTO) open sourced InfraKit during his keynote address at LinuxCon Europe in Berlin last month. InfraKit is a declarative management toolkit for orchestrating infrastructure built by two Docker core team engineers, David Chung and Bill Farner. Read this blog post to learn more about InfraKit origins, internals and plugins including groups, instances and flavors. During this online meetup, David and Bill explained what InfraKit is, what problems it solves, some use cases, how you can contribute and what’s coming next.    There are many ways you can participate in the development of the project and influence the roadmap: Star the project on GitHub to follow issues and development Help define and implement new and interesting plugins Instance plugins to support different infrastructure providers Flavor plugins to support a variety of systems like etcd or Continue reading…

Docker Weekly Roundup | October 23, 2016

  The last week of October 2016 is over and you know what that means; another Docker news roundup. Highlights include Windows workloads with Image2Docker, part four of the SwarmKit series, and a Docker InfraKit test-drive! As we begin a new week, let’s recap our five top stories: Windows Workloads with Image2Docker – a community supported and designed project to demonstrate the ease of creating Windows Containers from existing servers. Interested parties are encouraged to fork it, play with it and contribute pull requests back to the community. SwarmKit – Part 4 –  a tutorial series on Docker SwarmKit led by Gabriel Schenker. Part four of the series explains how to create a swarm in the cloud and run a sample application on it. Docker Volumes  – user instructions on how to make sure posts and images stay permanent via Docker volumes, even with an Continue reading…

Docker Distributed System Summit videos & podcast episodes

Following LinuxCon Europe in Berlin last week, we organized a first of its kind Docker event called Docker Distributed Systems Summit. This two day event was an opportunity for core Docker engineers and Docker experts from the community to learn, collaborate, problem-solve and hack around the next generation of distributed systems in areas such as orchestration, networking, security and storage. More specifically, the goal of the summit was to dive deep into Docker’s infrastructure plumbing tools and internals: SwarmKit, InfraKit, Hyperkit, Notary, libnetwork, IPVS, Raft, TUF and provide attendees with the working knowledge of how to leverage these tools while building their own systems. We’re happy to share with you all the videos recordings, slides and audio files available as #dockercast episodes! Youtube playlist Podcast playlist All the slides from the summit are available on the official Docker slideshare account. Please Continue reading…

Introducing InfraKit, an open source toolkit for creating and managing declarative, self-healing infrastructure

Written by Bill Farner and David Chung Docker’s mission is to build tools of mass innovation, starting with a programmable layer for the Internet that enables developers and IT operations teams to build and run distributed applications. As part of this mission, we have always endeavored to contribute software plumbing toolkits back to the community, following the UNIX philosophy of building small loosely coupled tools that are created to simply do one thing well. As Docker adoption has grown from 0 to 6 billion pulls, we have worked to address the needs of a growing and diverse set of distributed systems users. This work has led to the creation of many infrastructure plumbing components that have been contributed back to the community. It started in 2014 with libcontainer and libnetwork. In 2015 we created runC and co-founded OCI with an industry-wide set of partners to provide Continue reading…
