docker-registry-proxy

This is a simple Docker registry proxy. Due to the fact that Docker Registry mirror service provided by Chinese cloud service providers is only open to intranet, a proxy service is needed for access. This service is a simple proxy service that forwards requests to the specified Docker Registry.
