Open Container Project

Open Container Project is a big win for containers

The big news out of DockerCon so far is the announcement of the Open Container Project. Docker, CoreOS, and pretty much every big name in DevOps and container technologies have united to form the Open Container Project. OCP is dedicated to developing and maintaining standards for containers to ensure that different container technologies and platforms will work together and prevent fragmentation of the container market.

I wrote about the OCP news in the blog post:

A broad coalition of major tech companies has joined forced to create the Open Container Project—or OCP. The move to develop and maintain common standards around software containers vindicates the CoreOS split from Docker and reunites the two in a common cause that will make all container platforms and technologies stronger.

A press release announcing the Open Container Project explains the overall vision for OCP. “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.”

Docker and CoreOS are at the heart of OCP but they’re by no means alone. A veritable “Who’s Who” of DevOps and container technologies has enlisted to support OCP, including Amazon Web Services, Cisco, EMC, Google, HP, IBM, Linux Foundation, Microsoft, Red Hat, and VMware.

At one point Docker had a Standard Container Manifesto that spelled out some basic attributes it felt all containers should have. The Standard Container Manifesto called for containers to operate in a standard fashion, be content agnostic, infrastructure agnostic, and designed for automation among other things. When Docker removed the manifesto and seemed to shift to a more proprietary strategy CoreOS split off and launched its own container technology to continue the vision of a container standard.

“An open, well-defined specification is required for the overall success and adoption of containers. At CoreOS, when we started the App Container spec (appc) our goal was to have a well-designed software container specification. With the OCP, we have now come together with Docker and many industry giants in an effort to unify this goal.”

The launch of OCP and the laundry list of companies backing it show that CoreOS was not alone in its pursuit of the vision for a container standard. “We are excited to support this effort to bring the industry together to agree on a corestandard for containers, which we feel will benefit all customers no matter what cloud provider they use,” said Jason Zander, CVP, Microsoft Azure. “Through our close work with Docker over the last year we have demonstrated our commitment to openness and welcome this opportunity to help create an open platform for customers.”

You can read the full story on OCP is a victory of CoreOS and containers in general.
