containerd joins the Cloud Native Computing Foundation

Today, we’re excited to announce that containerd – Docker’s core container runtime – has been accepted by the Technical Oversight Committee (TOC) as an incubating project in the Cloud Native Computing Foundation (CNCF). containerd’s acceptance into the CNCF alongside projects such as Kubernetes, gRPC and Prometheus comes three months after Docker, with support from the five largest cloud providers, announced its intent to contribute the project to a neutral foundation in the first quarter of this year. In the process of spinning containerd out of Docker and contributing it to CNCF there are a few changes that come along with it.  For starters, containerd now has a logo; see below. In addition, we have a new @containerd twitter handle. In the next few days, we’ll be moving the containerd GitHub repository to a separate GitHub organization. Similarly, the containerd slack channel will be moved to separate slack team which will soon available at containerd.slack.com containerd has Continue reading…

containerd summit recap: slides, videos and meeting notes

Last week, we hosted a containerd summit for contributors and maintainers. Containerd is a core container runtime with an emphasis on simplicity, robustness and portability. It is available as a daemon for Linux and Windows, which can manage the complete container lifecycle of its host system: image transfer and storage, container execution and supervision, snapshot storage for container filesystems and a few other things to make the management of containers robust. We started off by getting everyone up to speed on the project, roadmap and goals before diving down into specific issues and design of containerd.  We had a couple breakout sessions where we discussed blocking issues and feature requests by various members of the community. You can see a summary of the breakout sessions in last week’s development report in the containerd repository and the various presentations below: Deep Dive into Continue reading…

More details about containerd, Docker’s core container runtime component

Today we announced that Docker is extracting a key component of its container platform, a part of the engine plumbing–containerd a core container runtime–and commits to donating it to an open foundation. containerd is designed to be less coupled, and easier to integrate with other tools sets. And it is being written and designed to address the requirements of the major cloud providers and container orchestration systems. Because we know a lot of Docker fans want to know how the internals work, we thought we would share the current state of containerd and what we plan for version 1.0. Before that, it’s a good idea to look at what Docker has become over the last three and a half years. The Docker platform isn’t a container runtime. It is in fact a set of integrated tools that allow you to build Continue reading…

containerd – a core container runtime project for the industry

Today Docker is spinning out its core container runtime functionality into a standalone component, incorporating it into a separate project called containerd, and will be donating it to a neutral foundation early next year. This is the latest chapter in a multi-year effort to break up the Docker platform into a more modular architecture of loosely coupled components. Over the past 3 years, as Docker adoption skyrocketed, it grew into a complete platform to build, ship and run distributed applications, covering many functional areas from infrastructure to orchestration, the core container runtime being just a piece of it. For millions of developers and IT pros, a complete platform is exactly what they need. But many platform builders and operators are looking for “boring infrastructure”: a basic component that provides the robust primitives for running containers on their system, bundled in Continue reading…
