I’ve followed along this blog [Using Nexus OSS as a proxy/cache for Docker images – Tech by Maarten](https://mtijhof.wordpress.com/2018/07/23/using-nexus-oss-as-a-proxy-cache-for-docker-images/) and created the daemon.json on docker mentioned and everything seems to be correctly configured but when I try to download an image it doesn’t cache into the proxy repository. I’ve create a hosted, proxy and group repository and when I use docker login, I connect to the group and try to pull an image, it always downloads from docker hub directly and I can’t cache it. What am I missing? ---

Hi, You’re having the same issue I have. I took a capture and saw that when using docker pull it first check that the repository support V2 and it does it anonymously even if you perform docker login I also opened a case on that. ---

Are you including the Nexus Repo hostname and port when issuing docker commands? [https://help.sonatype.com/repomanager3/formats/docker-registry/accessing-repositories](https://help.sonatype.com/repomanager3/formats/docker-registry/accessing-repositories) Rich ---

Yes, I am. I’ve configured a proxy, hosted and group repository. Each has a different port number and I can push images without any issues for the hosted repository. ---

> … but when I try to download an image it doesn’t cache into the proxy repository There is a “Foreign Layer Caching” option in the settings of the proxy-repository. Did you try to set it? [https://help.sonatype.com/repomanager3/formats/docker-registry/foreign-layers](https://help.sonatype.com/repomanager3/formats/docker-registry/foreign-layers) The blog article you mentioned was written for Nexus v3.15. “Foreign Layer Caching” option appeared in Nexus v3.19. In the sooner versions caching works by default, as i know.
