OCI Initial Delivery

[Vincinator]

Epic: OCI Initial Delivery

Scope

As Garden Linux adopter, I want to be able to pull my image of choice via Open Container Initiative (OCI)[1] Image Specification (image-spec) container layers, served for me from public registry.

[1] See https://opencontainers.org/about/overview/

High Level Architecture

The Architecture Diagram above shows the existing Garden Linux pipeline state, and the OCI extensions for the pipelines. Architectural decisions are:

• OCI pipelines are not blocking
• OCI Images are incrementally extended. (build artifacts, test artifacts, audit artifacts, arbitrary artifacts)
• OCI tool is a CLI that can be invoked from local workstation or from pipeline, and is independent of CI/CD syntax

Requirements

Architectural alignments and discussions

Before the initial implementation, a request for discussion was prepared. Summary of discussion is included in the RFD linked above.

Definition of done

• [ ] Tool to package Garden Linux release artefacts into OCI images, and upload them to a target OCI registry
  • https://github.com/gardenlinux/gl-oci
• [ ] Integration of tooling into release build pipelines of Garden Linux, so that Garden Linux release artefacts can be incrementally be attached to an OCI-image until it reaches a defined state of "final" including cryptographic signatures

• Topic has been handled with lower priority due to on-site workshop, urgent release work, sick leave.

June

• https://github.com/gardenlinux/process/issues/53
• ✅ Design and document how to integrate OCM with OCI
• ✅ Setup Development Environment (poetry, zot, makefile)
• ✅ Create OCI Image manifest and push it to a registry
• ✅ Extend an existing OCI Image manifest with additional layer
