Open Container Initiative


The Open Container Initiative is a Linux Foundation project to design open standards for operating-system-level virtualization, most importantly Linux containers. There are currently two specifications in development and in use: Runtime Specification and the Image Specification.
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 and it is included in RHEL 8.0 as a Docker replacement.
