Open Container Initiative
The Open Container Initiative (OCI) is a Linux Foundation project, started in June 2015 by Docker, to design open standards for operating-system-level virtualization (software containers), most importantly Linux containers. Initiative. There are currently two specifications in development and in use: "Runtime Specification" (runtime-spec) and the "Image Specification" (image-spec). OCI develops runc, a container runtime that implements their specification and serves as a basis for other higher-level tools. runC was first released in July 2015 as version 0.0.1.
