OCI Image Discovery Specifications

This repository contains two ref-engine discovery specifications:

• OCI Well Known URI Ref-Engine Discovery. There is a Go implementation in tools/refenginediscovery/wellknownuri. There is a Python 3 implementation in oci_discovery.ref_engine_discovery.well_known_uri.
• OCI XDG Ref-Engine Discovery. There is a Go implementation in tools/refenginediscovery/xdg. There is a Python 3 implementation in oci_discovery.ref_engine_discovery.xdg.

This repository also contains some related specifications:

• Host-Based Image Names There is a Go implementation in tools/hostbasedimagenames. There is a Python 3 implementation in oci_discovery.host_based_image_names.
• OCI Index Template Protocol There is a Go implementation in tools/refengine/indextemplate. There is a Python 3 implementation in oci_discovery.ref_engine.oci_index_template.
• OCI CAS Template Protocol

This repository also contains registries for ref- and CAS-engine protocols:

• Ref-Engine Protocols. There is a Go implemention in tools/refengine. There is a Python 3 implementation in oci_discovery.ref_engine.CONSTRUCTORS.
• CAS-Engine Protocols.

The strategies in these specifications are inspired by some previous implementations:

• ABD
• App Container Image Discovery
• parcel

Examples of using the local implementations to resolve an image name are here for Go and here for Python 3.

Examples of publishing images via static files and Nginx are here.
