Is there currently any way to mirror an official maven repo using Artifact Registry?

Question

I'm evaluating using Google Artifact Registry as a replacement for Nexus, and one thing that I have been unable to find in the documentation is if it is possible to mirror or proxy an official repository, for instance mavenCentral (like suggested on this site https://blog.sonatype.com/using-nexus-3-as-your-repository-part-1-maven-artifacts)

Has anyone else achieved this using Artifact Registry?

Answer 1

It is not currently possible to proxy/mirror upstream repositories with Artifact Registry. Support for upstream repositories is on the roadmap, with support for repos such as DockerHub, Maven, NPMJS and PyPi on the list. It will be a proxy / pull-through cache model.
