Authoritative Sources

The definitions, principles, and practices in this pack are grounded in the following primary and widely recognised sources. Where a concept has a canonical specification or maintained reference (for example the OCI specs or the Kubernetes documentation), that source is cited directly. Versions and behaviours described are current to stable Kubernetes (1.2x) and Docker/BuildKit at the time of authoring.
