A tour of containerd 1.0

  We have done a few talks in the past on different features of containerd, how it was designed, and some of the problems that we have fixed along the way. Containerd is used by Docker, Kubernetes CRI, and a few other projects but this is a post for people who may not know what containerd actually does within these platforms.  I would like to do more posts on the feature set and design of containerd in the future but for now, we will start with the basics. I think the container ecosystem can be confusing at times. Especially with the terminology that we use. Whats this? A runtime. And this? A runtime…  containerd (pronounced “container-dee”) as the name implies, not contain nerd as some would like to troll me with, is a container daemon.  It was originally built as an integration Continue reading…

Announcing the General Availability of containerd 1.0, the industry-standard runtime used by millions of users

Today, we’re pleased to announce that containerd (pronounced Con-Tay-Ner-D), an industry-standard runtime for building container solutions, has reached its 1.0 milestone. containerd has already been deployed in millions of systems in production today, making it the most widely adopted runtime and an essential upstream component of the Docker platform. Built to address the needs of modern container platforms like Docker and orchestration systems like Kubernetes, containerd ensures users have a consistent dev to ops experience. From Docker’s initial announcement last year that it was spinning out its core runtime to its donation to the CNCF in March 2017, the containerd project has experienced significant growth and progress over the past 12 months. . Within both the Docker and Kubernetes communities, there has been a significant uptick in contributions from independents and CNCF member companies alike including Docker, Google, NTT, IBM, Microsoft, AWS, Continue reading…

DockerCon Europe 2017 Highlights

DockerCon Europe 2017 is coming to an end and we’d like to thank all of the speakers, sponsors and attendees for contributing to the success of these amazing 3 days in Copenhagen. All the slides will soon be published on our slideshare account and all the breakout session videos recordings will soon be available on the docker website. DockerCon Day 1 Highlights On Tuesday, we announced that Docker will be delivering seamless integration of Kubernetes into the Docker platform. Adding Kubernetes support as an orchestration option (alongside Swarm) in both Docker Enterprise Edition, and in Docker for Mac and Windows will help simplify and advance the management of Kubernetes for enterprise IT and deliver the advanced capabilities of the Docker platform to a broader set of applications. To try the latest version of Docker Enterprise Edition, Docker for Mac and Windows with built-in Continue reading…

Docker Platform and Moby Project add Kubernetes

Today we’re announcing that the Docker platform is integrating support for Kubernetes so that Docker customers and developers have the option to use both Kubernetes and Swarm to orchestrate container workloads. Register for beta access and check out the detailed blog posts to learn how we’re bringing Kubernetes to: Docker Enterprise Edition Docker Community Edition on the desktop with Docker for Mac and Windows The Moby Project Docker is a platform that sits between apps and infrastructure. By building apps on Docker, developers and IT operations get freedom and flexibility. That’s because Docker runs everywhere that enterprises deploy apps: on-prem (including on IBM mainframes, enterprise Linux and Windows) and in the cloud. Once an application is containerized, it’s easy to re-build, re-deploy and move around, or even run in hybrid setups that straddle on-prem and cloud infrastructure. The Docker platform 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…

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…
