I created a Windows based docker image (asp.net web project) and pushed it to my private image registry.

when i pull the image from another windows server (offline and there is not a proxy), i'm getting the following error. As you can see the first two lines (system fs layer) tried to download many times, but it couldn't.

If I create an image and push the private registry, why does the pulling process try to download some layers from the internet?

I checked the ip address (204.79.197.219). It belongs to Microsoft.

How to resolve the issue?

Thank you for help

this could be the reason - https://docs.docker.com/registry/recipes/mirror/

Configure the Docker daemon Either pass the --registry-mirror option when starting dockerd manually, or edit /etc/docker/daemon.json and add the registry-mirrors key and value, to make the change persistent.

  • if some layers are from public repositories (e.g dockerhub), docker always downloads from internet. there are two options 1. we can manually pull from public repo and tag the image and push to private registery 2. we can use mirroring as Nathon mentioned Apr 7 at 7:32
