The record

Purpose: Ociregistry is a pull-only, pull-through caching OCI Distribution server.
Upstream registries: One instance can pull from multiple public, internal, or air-gapped upstream registries, including Docker Hub, Quay, registry.k8s.io, and GHCR.
Authentication and transport: Supported upstream access includes anonymous and basic authentication, HTTP and HTTPS, one-way TLS, and mutual TLS.
Cache storage: The server persists cache state as files in one filesystem subdirectory, which can be copied with the image store and served from another location.
Kubernetes use: The project is intended as an edge OCI Distribution server for Kubernetes, including edge clusters, air-gapped clusters, and registry offload.
Deployment: The project documents running the server locally or as a Kubernetes workload using a Helm chart available through Artifact Hub.
Registry client compatibility: The documentation demonstrates pulling through the server with Docker and also names Podman and Crane as supported client options.
External authentication: External token authentication is supported, and the documented token provider currently supports Amazon ECR.
Administrative API: The administrative REST API supports cache pruning and listing images, blobs, and manifests, as well as stopping the server.
Cache pruning: Pruning can target images by access time, creation time, or URL pattern, and supports a dry-run option.
Security-related transport: The project documents secure and insecure HTTPS modes, one-way TLS, and mutual TLS for upstream access.
Single-instance limit: Because the server uses an in-memory cache synchronized with Go mutexes, the documentation says only one instance can serve clients and multiple Kubernetes replicas behind a service are unsupported.
Path limit: The documented maximum image path length is four segments, with containerd namespace query parameters allowing an additional image-name segment.
License: The repository provides the software under a modified MIT License that permits use free of charge and includes a restriction against using it to train AI or machine-learning systems.
