Open Container Initiative (OCI) Releases v1.0 of Container Standards
Open, portable, vendor-neutral container specifications now available
SAN FRANCISCO, Calif. – 19 July, 2017 – The Open Container Initiative (OCI), an open source community for creating open industry standards around containers, today announced the debut release of its container runtime and image format specifications, comprised of Runtime Specification v1.0 (a specification for defining the lifecycle of a container) and Image Format Specification v1.0 (a specification for the container image format). Combined with efforts to create a formal certification program later this year, OCI is bringing a set of common, minimal, open standards and specifications around container technology to a reality.
OCI v1.0 specifications lay the foundation for container portability across different implementations to make it easier for customers to support portable container solutions. The OCI will launch a certification program shortly such that different implementations can demonstrate conformance to the specifications.
“The v1.0 release of the OCI specifications is a huge milestone for both the container community and the industry at large,” said Chris Aniszczyk, Executive Director, OCI. “By creating these open, accessible specifications, along with early deployments, we are bringing the industry closer to portability and standardization. This is no small feat, and I am incredibly proud of the OCI community for all the hard work that went into this release.”
The initial release comes following an integrated and collaborative effort among a diverse community made up of individual contributors and disparate organizations, including the project’s over 40 member organizations. Formed in June of 2015, the OCI was launched with the express purpose of developing vendor neutral container standards that provide the industry the ability to fully commit to container technologies today without the fear of lock-in. OCI began with a specification describing container runtime behavior and expanded a year later to include a container image specification. Since then, the community has also worked on projects including runtime-tools and image-tools, go-digest, and selinux.
While v1.0 represents a great deal of progress, marking a readiness for serious commercial adoption, there is still work to be done. The OCI community will be launching a formal certification program later this year while active and ongoing work is underway in terms of additional platform support and potential to add additional specification functionality or projects.
More information about the Runtime Specification v1.0 is available at https://github.com/opencontainers/runtime-spec/ and details on the Image Format v1.0 Specification can be found here: https://github.com/opencontainers/image-spec
