前言

.NET Core 2.1將于2021年8月21日結束支持，本來應該沒什么影響，該怎么用繼續用得了。

但是，如果你在生產環境使用了.NET Core 2.1容器鏡像，那就要注意了，從8月21日開始，.NET Core 2.1容器鏡像將不再在Docker Hub中提供:?

遷移方案

如果你依賴Docker Hub上的.NET Core 2.1容器鏡像，可以切換到使用MCR。

比如原來使用的microsoft/dotnet:2.1-aspnetcore-runtime，需要改用mcr.microsoft.com/dotnet/aspnet:2.1:

FROM?mcr.microsoft.com/dotnet/aspnet:2.1WORKDIR?/app COPY?.?. EXPOSE?80 ENTRYPOINT?["dotnet",?"WebApplication1.dll"]

下面是詳細的容器鏡像遷移列表：

SDK

microsoft/dotnet:2.1-sdk?->?mcr.microsoft.com/dotnet/sdk:2.1 microsoft/dotnet:2-sdk?->?mcr.microsoft.com/dotnet/sdk:2.1 microsoft/dotnet:2.1-sdk-stretch?->?mcr.microsoft.com/dotnet/sdk:2.1-stretch microsoft/dotnet:2.1-sdk-stretch-arm32v7?->?mcr.microsoft.com/dotnet/sdk:2.1-stretch-arm32v7 microsoft/dotnet:2.1-sdk-nanoserver-1809?->?mcr.microsoft.com/dotnet/sdk:2.1-nanoserver-1809 microsoft/dotnet:2.1-sdk-alpine?->?mcr.microsoft.com/dotnet/sdk:2.1-alpine microsoft/dotnet:2.1-sdk-bionic?->?mcr.microsoft.com/dotnet/sdk:2.1-bionic microsoft/dotnet:2.1-sdk-bionic-arm32v7?->?mcr.microsoft.com/dotnet/sdk:2.1-bionic-arm32v7 microsoft/dotnet:latest?->?mcr.microsoft.com/dotnet/sdk:2.1

aspnetcore runtime

microsoft/dotnet:2.1-aspnetcore-runtime?->?mcr.microsoft.com/dotnet/aspnet:2.1 microsoft/dotnet:2-aspnetcore-runtime->?mcr.microsoft.com/dotnet/aspnet:2.1 microsoft/dotnet:2.1-aspnetcore-runtime-stretch-slim?->?mcr.microsoft.com/dotnet/aspnet:2.1-stretch-slim microsoft/dotnet:2.1-aspnetcore-runtime-stretch-slim-arm32v7?->?mcr.microsoft.com/dotnet/aspnet:2.1-stretch-slim-arm32v7 microsoft/dotnet:2.1-aspnetcore-runtime-nanoserver-1809?->?mcr.microsoft.com/dotnet/aspnet:2.1-nanoserver-1809 microsoft/dotnet:2.1-aspnetcore-runtime-alpine?->?mcr.microsoft.com/dotnet/aspnet:2.1-alpine microsoft/dotnet:2.1-aspnetcore-runtime-bionic?->?mcr.microsoft.com/dotnet/aspnet:2.1-bionic microsoft/dotnet:2.1-aspnetcore-runtime-bionic-arm32v7?->?mcr.microsoft.com/dotnet/aspnet:2.1-bionic-arm32v7 microsoft/dotnet:aspnetcore-runtime->?mcr.microsoft.com/dotnet/aspnet:2.1

runtime

microsoft/dotnet:2.1-runtime?->?mcr.microsoft.com/dotnet/runtime:2.1 microsoft/dotnet:2-runtime?->?mcr.microsoft.com/dotnet/runtime:2.1 microsoft/dotnet:2.1-runtime-stretch-slim?->?mcr.microsoft.com/dotnet/runtime:2.1-stretch-slim microsoft/dotnet:2.1-runtime-stretch-slim-arm32v7?->?mcr.microsoft.com/dotnet/runtime:2.1-stretch-slim-arm32v7 microsoft/dotnet:2.1-runtime-nanoserver-1809?->?mcr.microsoft.com/dotnet/runtime:2.1-nanoserver-1809 microsoft/dotnet:2.1-runtime-alpine?->?mcr.microsoft.com/dotnet/runtime:2.1-alpine microsoft/dotnet:2.1-runtime-bionic?->?mcr.microsoft.com/dotnet/runtime:2.1-bionic microsoft/dotnet:2.1-runtime-bionic-arm32v7?->?mcr.microsoft.com/dotnet/runtime:2.1-bionic-arm32v7 microsoft/dotnet:runtime?->?mcr.microsoft.com/dotnet/runtime:2.1

runtime-deps

microsoft/dotnet:2.1-runtime-deps?->?mcr.microsoft.com/dotnet/runtime-deps:2.1 microsoft/dotnet:2.1-runtime-deps-stretch-slim?->?mcr.microsoft.com/dotnet/runtime-deps:2.1-stretch-slim microsoft/dotnet:2.1-runtime-deps-stretch-slim-arm32v7?->?mcr.microsoft.com/dotnet/runtime-deps:2.1-stretch-slim-arm32v7 microsoft/dotnet:2.1-runtime-deps-alpine?->?mcr.microsoft.com/dotnet/runtime-deps:2.1-alpine microsoft/dotnet:2.1-runtime-deps-bionic?->?mcr.microsoft.com/dotnet/runtime-deps:2.1-bionic microsoft/dotnet:2.1-runtime-deps-bionic-arm32v7?->?mcr.microsoft.com/dotnet/runtime-deps:2.1-bionic-arm32v7 microsoft/dotnet:runtime-deps?->?mcr.microsoft.com/dotnet/runtime-deps:2.1

結論

微軟還算良心，提供了替代的微軟容器注冊中心。

如果你準備使用了.NET Core容器鏡像，建議從一開始就從mcr.microsoft.com拉取。
