Moby Project and Open Source Summit North America

Docker will be at Open Source Summit in Los Angeles, CA from September 11-14th to highlight new development with the Moby Project and it’s various components: containerd, LinuxKit, InfraKit, Notary, etc. Come see us at Booth #510 to learn more about: The different uses cases for the Moby Projects and components The difference between Docker and the Moby Project How to get started with each component As part of the OSS NA, Docker is also organizing a Moby Summit on September 14, 2017. Following the success of the previous editions, we’ll keep the same format which consists of short technical talks / demos in the morning and Birds-of-a-Feather in the afternoon.  We have an excellent line up of speakers in store for you and are excited to share the agenda below. We hope that these sessions inspire you to come participate in the Continue reading…

Docker Leads OCI Release of v1.0 Runtime and Image Format Specifications

Today marks an important milestone for the Open Container Initiative (OCI) with the release of the OCI v1.0 runtime and image specifications – a journey that Docker has been central in driving and navigating over the last two years. It has been our goal to provide low-level standards as building blocks for the community, customers and the broader industry. To understand the significance of this milestone, let’s take a look at the history of Docker’s growth and progress in developing industry-standard container technologies. The History of Docker Runtime and Image Donations to the OCI Docker’s image format and container runtime quickly emerged as the de facto standard following its release as an open source project in 2013. We recognized the importance of turning it over to a neutral governance body to fuel innovation and prevent fragmentation in the industry. Working Continue reading…

Moby Summit LA alongside Open Source Summit North America

Since the Moby Project introduction at DockerCon 2017 in Austin last April, the Moby Community has been hard at work to further define the Moby project, improve its components (runC, containerd, LinuxKit, InfraKit, SwarmKit, Libnetwork and Notary) and fine processes and clear communication channels. All project maintainers are developing these aspects in the open with the support of the community. Contributors are getting involved on GitHub, giving feedback on the Moby Project Discourse forum and asking questions on Slack. Special Interest Groups (SIGs) for the Moby Project components have been formed based on the Kubernetes model for Open Source collaboration. These SIGs ensure a high level of transparency and synchronization between project maintainers and a community of heterogeneous contributors. In addition to these online channels and meetings, the Moby community hosts regular meetups and summits. Check out the videos and slides from the last Continue reading…

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…
