push linux containers to stefanscherer/registry-windows?

[scottdcarson]

I'm not sure if this is supposed to work or not, and if not, why. I have a functioning registry (thank you so much for that!) and I build and push windows images to it routinely. Now I'm trying to push a linux image (aspnet 3.1-focal aka ubuntu 20.04) to it and it seems to work (even gets part of the way through) but just hangs. For example:

docker pull mcr.microsoft.com/dotnet/aspnet:3.1-focal
docker tag  mcr.microsoft.com/dotnet/aspnet:3.1-focal my-registry.internal/aspnet:3.1-focal
docker push my-registry.internal/aspnet:3.1-focal

I'll get something like this:

The push refers to repository [my-registry.internal/aspnet]
2c9650081f30: Pushing [============>                                      ]  4.417MB/18.24MB
4361eed95611: Pushing [==>                                                ]  3.841MB/77.3MB
61d1fce9f418: Pushing [==================================================>]   8.36MB/8.36MB
9010b92c40be: Pushing [==========================================>        ]  42.92MB/50.85MB
2f140462f3bc: Pushing [==================================================>]  70.14kB/70.14kB
63c99163f472: Pushing [==================================================>]  139.8kB/139.8kB
ccdbb80308cc: Pushing [==============>                                    ]  23.41MB/82.4MB

but then it just hangs (not always at the same place). FWIW, I'm doing this on the server that's running the registry container - LTSC2019 with LCOW enabled. Pushing (the more typical) nanoserver images works flawlessly and quickly.

Is there a conceptual problem I'm missing regarding storing linux images in this registry? I would have though that the images were just layers of data, uninterpreted by the registry and that this would have worked. Or is this a bug, or something with a workaround I have yet to discover?

The goal is to build .net core images for both focal and nanoserver and store them in the same place.

Thank you again for a most helpful product.

Technically it should work to store Linux images. They all look the same in a registry. But I haven't used this registry image for a long time. Maybe there are bugfixes/improvements that my images does not have.
