.NET Core latest Docker tags updated to 3.1

The latest tags for the dotnet/core repos have been updated to reference .NET Core 3.1.

Details

• dotnet-docker#1509

The latest tags for the dotnet/core repos are always intended to reference the latest supported version of .NET Core. At this time, the latest supported version is .NET Core 3.1. This version of .NET Core is also a long-term supported (LTS) release.

The following Docker repos have been updated:

• dotnet/core/sdk
• dotnet/core/aspnet
• dotnet/core/runtime
• dotnet/core/runtime-deps

It is recommended to use a more-specific tag than latest for anything other than casual development. Once you have an application that you believe will eventually go to production, you are recommended to use a tag like 3.1.

I tried yesterday and again today to pull and use the Debian 10 '3.1.100' SDK image and get i/o timeout errors pulling image configuration. The 3.0.100 image reference does not do this.

Error:
error pulling image configuration: Get https://mcreus0.blob.core.windows.net/aba285c624a04409823b708c7a50e7b9-jttfjm99vo//docker/registry/v2/blobs/sha256/98/9817c25953a8ede59da1b397aa096c5ba269bbd969f55f1819393dda35f9d19f/data?se=2019-12-06T22%3A24%3A25Z&sig=n9whbNNyggFZrjyz9yyFU60hF3bgyf4yYno%2FVqpsZzM%3D&sp=r&sr=b&sv=2016-05-31&regid=aba285c624a04409823b708c7a50e7b9: dial tcp: lookup mcreus0.blob.core.windows.net on 192.168.65.1:53: read udp 192.168.65.3:43777->192.168.65.1:53: i/o timeout

Image reference being used is:

FROM mcr.microsoft.com/dotnet/core/sdk:3.1.100

Anyone else run into this?

@4deeptech , I have not had any issues. I'd suggest reporting the issue at https://github.com/microsoft/containerregistry.

This is using VSCode remote containers with Docker Desktop. I just now switched my docker file back to:

FROM mcr.microsoft.com/dotnet/core/sdk:3.0.100

and it fired right up.

I will report this over there and see if anyone knows anything about this. Thanks.
