KubeCon NA 2018 Wrap Up: Docker and the Kubernetes Community
Right on the heels of DockerCon Europe, the Docker team was excited to be a part of KubeCon in Seattle last week for great conversations and collaboration with the Kubernetes community. In addition to our commitment to delivering a simple, integrated experience with Kubernetes in our Docker Desktop and Docker Enterprise products, we’re also excited by our work with the community at the very foundation of Kubernetes with projects like containerd and Notary/TUF and to talk container standards with the members of the Open Container Initiative (OCI). KubeCon is an opportunity for project maintainers to explain the status and roadmap of projects, but also to meet face to face and collaborate with contributors to determine what is next for cloud native applications.
Giving Back to the Kubernetes Community
The Docker and Kubernetes communities have been working together closely since Kubernetes was announced at DockerCon 2014. In line with our commitment to continue to make containerization technology like Kubernetes easier to use: a few weeks ago we open sourced Docker Compose on Kubernetes, a project that provides a simple way to define cloud native applications with a higher-level abstraction, the Docker Compose file. Docker Compose is a tool Continue reading
Announcing Cloud Native Application Bundle (CNAB)
As more organizations pursue cloud-native applications and infrastructures for creating modern software environments, it has become clear that there is no single solution in the market for defining and packaging these multi-service, multi-format distributed applications. Real-world applications can now span on-premises infrastructure and cloud-based services, requiring multiple tools like Terraform for the infrastructure, Helm charts and Docker Compose files for the applications, and CloudFormation or ARM templates for the cloud-services. Each of these need to be managed separately.
To address this problem, Microsoft in collaboration with Docker are announcing Cloud Native Application Bundle (CNAB) – an open source, cloud-agnostic specification for packaging and running distributed applications. CNAB unifies the management of multi-service, distributed applications across different toolchains into a single all-in-one packaging format.The CNAB specification lets you define resources that can be deployed to any combination of runtime environments and tooling including Docker Engine, Kubernetes, Helm, automation tools and cloud services.
Docker is the first to implement CNAB for containerized applications and will be expanding it across the Docker platform to support new application development, deployment and lifecycle management. Initially CNAB support will be released as part of our docker-app experimental tool for building, packaging and managing Continue reading
Docker and MuleSoft Partner to Accelerate Innovation for Enterprises
A convergence of forces in SaaS, IoT, cloud, and mobile have placed unprecedented requirements on businesses to accelerate innovation to meet those rapidly changing preferences. The big don’t eat the small, the fast eat the slow.
The industry has offered several solutions to this acceleration problem – from working harder to outsourcing and devops, but none of those solutions have really offered the levels of acceleration needed. The reason: there is too much friction slowing the art of the possible.
Docker and MuleSoft remove friction in the innovation process, from ideation all the way to deployment. MuleSoft provides a tops down architectural approach, with API-first design and implementation. The Docker approach is bottoms up from the perspective of the application workload with containerization, to both modernize traditional applications and create of new applications.
Marrying those two approaches combined with the platform, tools and methodology, enable both organizations to help your business accelerate faster than ever before. Docker and MuleSoft bridge the chasm between infrastructure and services in a way never before achieved in the industry.
Together, Docker and MuleSoft accelerate legacy application modernization and new application delivery while reducing IT complexity and costs.
- Modernize traditional applications quickly without code Continue reading
Cool Hacks Spotlight: Gloo Function Gateway
To close DockerCon Cool Hacks keynote, Idit Levine from Solo.io presented Gloo, a high-performance, plugin-extendable, platform-agnostic function Gateway built on top of Envoy.
Idit showed a demo that involved modernizing a traditional application; the classic Spring Pet Clinic sample app, by containerizing it and deploying it to Docker Enterprise Edition. She added functionality to the app by adding a microservice written in Go through a Gloo route. Then added more functionality by adding a Gloo route to an AWS Lambda function, creating a true hybrid cloud application combining legacy, microservices and serverless components.
She then provided a demo of Squash, that works with Gloo to live debug two microservices forming an application running in Kubernetes on Docker Enterprise Edition, one in Java from IntelliJ, one in Go from Visual Studio Code.
She finished her presentation by announcing and open sourcing Qloo, a GraphQL Server built on top of Gloo and the Envoy Proxy. This allows you to add GraphQL support without any coding to your existing application, and combining functions together in a workflow described as a graph.
See all these excellent demos in the video below, and view the presentation on SlideShare.

DockerCon Updates on Containerd, BuildKit, and a Reflection about the Enduring Value of Docker Engine
Two weeks ago was our eighth DockerCon in just four years. Our community of contributors, developers, IT users, enterprises and ecosystem partners has grown exponentially into the millions, anchored on our founder Solomon Hykes’ simple premise of democratizing the use of the software container. Today as was from the beginning, Docker creates simple tooling and a universal packaging approach that bundles up all application dependencies inside the container. Docker Engine enables applications to run anywhere consistently on any infrastructure, solving “dependency hell” for developers and operations teams, and eliminating the “it works on my laptop!” problem.
In the past 2 years, Docker Engine’s codebase has been refactored into several reusable components, the most important being containerd, the core container runtime, and BuildKit, the part of Docker Engine used to build images. In the contribute and collaborate track at DockerCon, Michael Crosby and Tonis Tiigli gave an update on these two projects (video, slides)

Announcing DockerCon 2018 Session: Cool Hacks
One of the most anticipated sessions at DockerCon is Cool Hacks, where we showcase a few members of the Docker community pushing the envelope on what you can achieve with Docker, in a demo heavy session, showing trends of what innovators are building on top of the Docker platform. This year, we’ll talk about Space, AI and Serverless!
Past Cool Hacks have gone to be widely used: last year Marcos Nils and Jonathan Leibiusky showed Play with Docker, a Docker playground that you can run in your browser that is now used by tens of thousands of developers and system administrators monthly to learn the basics on Docker and was applied to learning Kubernetes with Play with Kubernetes; And Alex Ellis demoed a FaaS, a portable serverless platform running on top of Swarm, that grew into the OpenFaaS project, one of the 12 installable serverless platforms mentioned in the Cloud Native Foundation Serverless Working Group serverless landscape.
This post should whet your appetite for what to expect in Dockercon 2018 Cool Hacks session.

Top 5 Blogs of 2017: Docker Platform and Moby Project add Kubernetes
As we count down the final days of 2017, we would like to bring you the final installment of the top 5 blogs of 2017. On day 5, we take a look back DockerCon EU, when we announced Kubernetes support in the Docker platform. This blog takes an in-depth look at the industry-leading container platform and the addition of Kubernetes.
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 is composed of many 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, ZTE, Huawei and ZJU. Similarly, the maintainers have been working to add key functionality to containerd.The initial containerd donation provided everything users need to ensure a seamless container experience including methods for:
- transferring container images,
- container execution and supervision,
- low-level local storage and network interfaces and
- the ability to work on both Linux, Windows and other platforms. Continue reading
Docker Spearheads 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 together with a broad group of container technologists and industry leaders, the Open Container Project was formed to create a set of container standards and was launched under the auspices of the Linux Foundation in June 2015 at DockerCon. It became the Open Container Initiative (OCI) as the project evolved that Summer.
Docker contributed runc, a reference implementation for the Continue reading
Moby Summit June 2017 Recap
On June 19 2017, 90 members of the Moby community gathered at Docker headquarter in San Francisco for the second Moby Summit. This was an opportunity for the community to discuss the progress and future of the Moby project, two months after it was announced.
We started the day with an introduction by Solomon Hykes, and a look at the website redesign: the Moby project website now has a blog, an event calendar, a list of projects, and a community page with links to various community resources. The website code is open source, issues and PRs to make it better are welcome.
Then each team gave an update on their progress: Linuxkit, containerd, InfraKit, SwarmKit and LibNetwork, as well as the three new Moby Special Interest Groups, Linuxkit Security, Security Scanning & Notary and Orchestration Security. All these talks have been recorded and you can find the videos and slides below.
In the afternoon, we split into 5 Birds Of Feathers (BOF) sessions: runc/containerd, LinuxKit, InfraKit, Security, and Security Scanning. You can find links to the BOF Notes at the end of this post.
We ended the day with a recap of the BOF sessions, and Continue reading
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 been extracted from Docker’s container platform and includes methods for transferring container images, container execution and supervision and low-level local storage, across both Linux and Windows. containerd is an essential upstream component of the Docker platform used by millions of end users that also provides the industry with an open, 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 ship and run distributed applications. That means Docker handles networking, infrastructure, build, orchestration, authorization, security, and a variety of other services that cover the complete distributed application lifecycle.
The core container runtime, which is containerd, is a small but vital part of the platform. We started breaking out containerd from the rest of the engine in Docker 1.11, Continue reading
