前言

.NET Core 2.1將于2021年8月21日結(jié)束支持，本來應(yīng)該沒什么影響，該怎么用繼續(xù)用得了。

但是，如果你在生產(chǎn)環(huán)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(xì)的容器鏡像遷移列表：

結(jié)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(zhǔn)備使用了.NET Core容器鏡像，建議從一開始就從mcr.microsoft.com拉取。

如果你覺得這篇文章對你有所啟發(fā)，請關(guān)注我的個(gè)人公眾號”My IO“，記住我！

總結(jié)

以上是生活随笔為你收集整理的强制升级？！.NET Core 2.1容器镜像将从Docker Hub中删除的全部內(nèi)容，希望文章能夠幫你解決所遇到的問題。
