I hoped it was a new post, but it is the one from july. I would like to create a read-only registry, using only Nginx. This page http://docs.docker.io/en/latest

I hoped it was a new post, but it is the one from july. I would like to create a read-only registry, using only Nginx. This page http://docs.docker.io/en/latest/api/registry_api/ http://docs.docker.io/en/latest/api/registry_api/ has some information but not everything. For instance, the very first thing `docker pull` does is doing a check as GET /v1/_ping, and looking for some X-Docker-Registry-Version header. The _ping route, or the version check are undocumented. (Not a rant, Docker is evolving quite fast, and its documentation too.)
