The Open Container Initiative (OCI) serves as an open governance framework aimed at developing industry-wide standards for container formats and runtimes. Launched on June 22, 2015, by Docker alongside other prominent figures in the container sector, the OCI encompasses two main specifications: the runtime specification (runtime-spec) and the image specification (image-spec). The runtime specification delineates the process for executing a "filesystem bundle" that has been extracted onto a disk. In practice, an OCI implementation would download an OCI Image, subsequently unpacking it into a corresponding OCI Runtime filesystem bundle. Following this, the OCI Runtime is responsible for executing the OCI Runtime Bundle. Additionally, the OCI operates as a lightweight governance project under the Linux Foundation, promoting transparency and collaboration within the container ecosystem. Its establishment marked a significant step forward towards unifying diverse container technologies and ensuring interoperability across platforms.
