[note] OCI Artifact?

📌 What is an OCI Artifact?

The full name of OCI Artifact is Open Container Initiative Artifact. It is a unified format that can be used to store anything — whether it’s a Docker image, Helm chart, WASM module, ML model, SBOM, policy, or scan report.

Most importantly, anything that follows the OCI format can be uploaded to or downloaded from a registry (e.g., Harbor, DockerHub, Artifact Hub).

🚀 OCI Artifact Structure

• Tag – A human-readable name (e.g., nginx:1.0) that points to a manifest or index. Tags are version labels.
• Index – A list of manifests, often used for multi-platform artifacts.
• Manifest – Describes an artifact (e.g., Docker image, Helm chart) and references blobs.
• Blobs – Actual content like .tar.gz, binaries, or configs used by the artifact.
