It’s Back… The Contribute and Collaborate track returns to DockerCon 2018

A significant number of Docker early adopters, advanced container users and Open Source lovers come to DockerCon to contribute to open source projects and collaborate on technical system implementations. Last year, these activities were taking place at the Moby Summit scheduled on the last day of the conference. Listening to feedback from attendees who expressed interest in participating in such activities earlier in the week, we’ve decided to bring back the Contribute & Collaborate track to the main conference days! The goal of this track is to raise awareness and educate users around the upstream components of the Docker Platform, provide a path for new contributors and unleash new opportunities for innovation and collaboration within the broader Cloud Native and Open Source communities. This track is organized in 4 half days (one for each of the categories below). Each will start Continue reading…

Top 5 blogs of 2017: LinuxKit, A Toolkit for building Secure, Lean and Portable Linux Subsystems

In case you’ve missed it, this week we’re highlighting the top five most popular Docker blogs in 2017. Coming in the third place is the announcement of LinuxKit, a toolkit for building secure, lean and portable Linux Subsystems.   LinuxKit includes the tooling to allow building custom Linux subsystems that only include exactly the components the runtime platform requires. All system services are containers that can be replaced, and everything that is not required can be removed. All components can be substituted with ones that match specific needs. It is a kit, very much in the Docker philosophy of batteries included but swappable. LinuxKit is an open source project available at https://github.com/linuxkit/linuxkit. To achieve our goals of a secure, lean and portable OS,we built it from containers, for containers.  Security is a top-level objective and aligns with NIST stating, in their Continue reading…

Docker for Windows 17.11 with Windows 10 Fall Creators Update

Experimental support for Microsoft’s Linux containers on Windows (LCOW) feature has been available for Windows Server 1709 via the Docker EE “Preview” release. The same functionality is now available for Windows 10 Fall Creators Update with the release of Docker for Windows 17.11. In fact, it’s been available since Docker for Windows 17.10.  How to get it Docker for Windows 17.11 is an Edge channel release. If your copy of Docker for Windows is set to the Edge or Nightly channel you will receive the update automatically. Users on the Stable channel will need to switch to Edge via the Setting dialog to receive the update. Doesn’t Docker for Windows already run Linux containers? That’s right. Docker for Windows can run Linux or Windows containers, with support for Linux containers via a Hyper-V Moby Linux VM (as of Docker for Continue reading…

Kubernetes 1.8 release integrates with containerd 1.0 Beta

Intent of containerd effort When containerd was first developed it had two goals. The first was to solve the upgrade problem with running containers and provide a codebase where OCI runtimes, like runc, could be integrated into Docker.  However, as needs change in the container space and after speaking  with various members of the community at the beginning of this year, we decided to expand the scope of containerd and make it a fully functional container daemon with storage, image distribution and runtime. containerd fully supports the OCI Runtime and Image specifications that are part of the recently released 1.0 specifications. Additionally, it was important to build a stable runtime for users and platform builders. We wanted containerd to be fully functional; but also, it needed to retain a small core codebase so that it is easy to maintain and support in the long run with an Continue reading…

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…

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…

Online meetup recap: Introduction to LinuxKit

At DockerCon 2017 we introduced LinuxKit: A toolkit for building secure, lean and portable Linux subsystems. Here are the key principles and motivations behind the project: Secure defaults without compromising usability Everything is replaceable and customizable Immutable infrastructure applied to building Linux distributions Completely stateless, but persistent storage can be attached Easy tooling, with easy iteration Built with containers, for running containers Designed for building and running clustered applications, including but not limited to container orchestration such as Docker or Kubernetes Designed from the experience of building Docker Editions, but redesigned as a general-purpose toolkit Designed to be managed by external tooling, such as Infrakit or similar tools Includes a set of longer-term collaborative projects in various stages of development to innovate on kernel and userspace changes, particularly around security For this Online Meetup, Docker Technical Staff member Rolf Neugebauer gave 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…
