Facts

Purpose
Ociregistry is a pull-only, pull-through caching OCI Distribution server.github.com · 4 Oct 2026
Upstream registries
One instance can pull from multiple public, internal, or air-gapped upstream registries, including Docker Hub, Quay, registry.k8s.io, and GHCR.aceeric.github.io · 4 Oct 2026
Authentication and transport
Supported upstream access includes anonymous and basic authentication, HTTP and HTTPS, one-way TLS, and mutual TLS.aceeric.github.io · 4 Oct 2026
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.github.com · 4 Oct 2026
Kubernetes use
The project is intended as an edge OCI Distribution server for Kubernetes, including edge clusters, air-gapped clusters, and registry offload.aceeric.github.io · 4 Oct 2026
Deployment
The project documents running the server locally or as a Kubernetes workload using a Helm chart available through Artifact Hub.github.com · 4 Oct 2026
Registry client compatibility
The documentation demonstrates pulling through the server with Docker and also names Podman and Crane as supported client options.aceeric.github.io · 4 Oct 2026
External authentication
External token authentication is supported, and the documented token provider currently supports Amazon ECR.aceeric.github.io · 4 Oct 2026
Administrative API
The administrative REST API supports cache pruning and listing images, blobs, and manifests, as well as stopping the server.aceeric.github.io · 4 Oct 2026
Cache pruning
Pruning can target images by access time, creation time, or URL pattern, and supports a dry-run option.aceeric.github.io · 4 Oct 2026
Security-related transport
The project documents secure and insecure HTTPS modes, one-way TLS, and mutual TLS for upstream access.aceeric.github.io · 4 Oct 2026
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.aceeric.github.io · 4 Oct 2026
Path limit
The documented maximum image path length is four segments, with containerd namespace query parameters allowing an additional image-name segment.aceeric.github.io · 4 Oct 2026
