An HTTPS caching proxy for Docker registries that provides centralized configuration and caching of image pulls from any registry (DockerHub, quay.io, ghcr.io, registry.k8s.io). It caches large blob/layer downloads to save bandwidth and can cache manifest requests to avoid DockerHub pull rate limits, while centrally managing registry authentication.

Use cases

• cache docker images from dockerhub to avoid rate limits
• set up a pull-through cache proxy for container registries
• reduce bandwidth usage when pulling docker images across a cluster
• centrally manage docker registry credentials for a kubernetes cluster
• mirror quay.io ghcr.io and registry.k8s.io behind one proxy
• avoid toomanyrequests errors when pulling from docker hub

When to choose

• you run kubernetes clusters or CI farms that pull the same images repeatedly and hit DockerHub rate limits
• you want to cache layers/blobs from multiple registries through a single self-hosted proxy
• you need centralized registry authentication instead of configuring imagePullSecrets everywhere
• you want to cut egress bandwidth and pull latency by serving cached layers locally

When to avoid

• you need a full registry with push support - this is a pull-through cache, not a registry you can push to
• you cannot install a CA certificate on the clients that will use the proxy
• you only pull images occasionally from a single machine where rate limits are not a concern
• you need a managed cloud solution rather than running your own proxy container
