Docker to donate container format, runtime code and specifications to Project
SAN FRANCISCO – DOCKERCON – June 22, 2015 – A broad coalition of industry leaders and users are joining forces to create the Open Container Project (OCP), chartered to establish common standards for software containers.
Housed under the Linux Foundation, the OCP’s mission is to enable users and companies to continue to innovate and develop container-based solutions, with confidence that their pre-existing development efforts will be protected and without industry fragmentation. As part of this initiative, Docker will donate the code for its software container format and its runtime, as well as the associated specifications. The leadership of the Application Container spec (“appc”) initiative, including founding member CoreOS, will also be bringing their technical leadership and support to OCP.
The container movement has gained immense popularity among users because of the promise of portability, agility and interoperability across a broad set of infrastructures and tools. The rapid proliferation of container-based solutions – supported and leveraged by an ecosystem of millions of developers, tens of thousands of enterprises, thousands of contributors and hundreds of technology companies – has inspired industry leaders to collaborate on an open, standard container format and runtime in order to preserve that portability and interoperability for users.
Managed under a vendor-neutral, open source, open governance model, the OCP will remain independent from any company or company-sponsored project. Interest in building open standards around containers has spread rapidly and the founders of the OCP include Amazon Web Services, Apcera, Cisco, CoreOS, Docker, EMC, Fujitsu Limited, Goldman Sachs, Google, HP, Huawei, IBM, Intel, Joyent, Linux Foundation, Mesosphere, Microsoft, Pivotal, Rancher Labs, Red Hat and VMware. Others interested in supporting the Project can find more information at http://www.opencontainers.org.
Docker donates its de facto standard technology
As part of the new Project, Docker will donate both draft specifications and its existing code around an image format and container runtime to serve as cornerstone technologies under the governance of the OCP.
Over the past two years, Docker’s image format and container runtime have emerged as the de facto standard, with support across every major Linux distribution, Microsoft Windows, every major public cloud provider, all leading virtualization platforms and most major CPU architectures, including: x86, ARM, z and POWER System p. Containers based on Docker’s image format have been downloaded more than 500 million times in the past year alone and there are now more than 40,000 public projects based on the Docker format. With these technologies as a base for its initiatives, the OCP can have evolved standards and specifications that are rooted in practical usage, code that has been used broadly in production and the collective experience of a large community of users and developers.
The OCP will manage the transition of the technology from an “insider” standard into an open industry standard, providing for its continued evolution. The Docker project will continue to maintain the Docker client, all platform tooling and all Docker orchestration capabilities that are built on top of the donated technologies. Other projects and companies will also be able to build technologies on the OCP format and runtime.
“Containers are revolutionizing the computing industry and delivering on the dream of application portability,” said Jim Zemlin, executive director of the Linux Foundation. “With the Open Container Project, Docker is ensuring that fragmentation won’t destroy the promise of containers. Users, vendors and technologists of all kinds will now be able to collaborate and innovate with the assurance that neutral open governance provides. We applaud Docker and the other founding members for having the will and foresight to get this done.”
The OCP image format will be backwards compatible with the Docker image format and appc and will include efforts to harmonize with other container efforts in the community.
The guiding principles around OCP standards are that they will:
- not be bound to higher level constructs such as a particular client or orchestration stack
- not be tightly associated with any particular commercial vendor or project and
- be portable across a wide variety of operating systems, hardware, CPU architectures, public clouds, etc.
The Open Container Project: Goals for Standardization
The charter of the OCP is to establish set of common, minimal standards around container technology. In establishing the goals for the OCP, the Project has taken into account standardization efforts that are already underway by other ecosystem members. The maintainers of Docker’s libcontainer project (a group that currently includes independent developers and individuals from Docker, Red Hat and Google) will become the lead maintainers for the OCP, joined by two prominent maintainers of appc. They will support open design and contribution based upon the guiding principles of the effort.
The OCP and its members will work together to build a standard that ensures container formats and runtime are based on a core set of values that includes openness, security, portability, composability, minimalism and backward compatibility. Within three months, the parties aim to complete creating the Project, migrating code and publishing a draft specification building on the technology donated by Docker.

“It’s great to see the industry and community join together on the Open Container Project. We believe this is important for the industry to accelerate the use and deployment of containers and micro-services,” said Dave Ward, chief architect and CTO of engineering, Cisco. “We look forward to the emerging developer community to further support container management, tooling and applications that will benefit users and integrate with other communities to be a common architectural building block.”
“CoreOS, when we started the App Container spec (appc) our goal was to have a well-designed software container specification that is modular, portable across platforms and is secure,” said Alex Polvi, co-founder and CEO of CoreOS. “An open, well-defined specification is required for the overall success and adoption of containers. Today we join forces with Docker and other industry giants in an effort to unify this goal.”
“After receiving feedback from the community, partners and customers, we believe the timing is right to create a common standard that would ensure compatibility and encourage innovation throughout the ecosystem,” said Solomon Hykes, founder and creator of the Docker open source initiative. “It is for this reason that we are donating our container format and runtime to the standard. We believe that after two years, the Docker container runtime code and technology have matured to the point that they would benefit from independent governance outside the Docker project. The strength of Docker has always been about getting the community to join forces and avoid fragmentation. This coalition is just another example of the community coming together to create a standard that will create stability while fostering greater productivity.”
“EMC has been aggressively focused on 3rd platform IT architectures including the use of new container based technology in our products and solutions. We are excited to help launch and support the OCP effort as the risk of overly fragmented technology will only slow down the adoption by our customers. At its core, 3rd platform is all about creating speed of creation and deployment of high value applications so efforts like OCP help align the industry in taking friction and unnecessary complexity out of the overall IT stack.”
—John Roese, chief technology officer, EMC and chairman, Cloud Foundry Foundation.
“During the nearly two decades that Fujitsu has actively supported Linux, the consensus that open source software is one of the most important choices for IT infrastructure has been reached.
