## What it is
A public container image mirror service by DaoCloud that accelerates pulling images from foreign registries like gcr.io, ghcr.io, quay.io, and docker.io, primarily for users in China. It works by adding a prefix (e.g., m.daocloud.io) to image names, with lazy-loading sync so hashes match the source registry.

## Use cases
- pull gcr.io images fast from China
- speed up docker image downloads behind slow international networks
- mirror container images for kubeadm cluster setup
- cache registry images for an intranet
- accelerate quay.io and ghcr.io pulls
- set up registry-mirrors for docker daemon

## When to choose
- you are in China or on a slow route to major registries and need faster image pulls
- you want a zero-code, prefix-based mirror for docker.io, gcr.io, ghcr.io, quay.io, registry.k8s.io, mcr.microsoft.com, nvcr.io, or docker.elastic.co
- you need a kubeadm imageRepository replacement or an internal pull cache

## When to avoid
- you need guaranteed SLAs or unlimited throughput (the public service has whitelists and rate limits)
- you need a private registry with push support - this is a pull-through mirror only
- you can access source registries directly at full speed
- you need images cached longer than 30 days without re-sync
