Docker中pull microsoft/dotnet报错

报错

今天在一台新的服务器中pull microsoft/dotnet的时候报错了

docker: Error response from daemon: pull access denied for microsoft/dotnet, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.

原因

这是因为.NET Core 2.1 和 2.2 容器映像已从 Docker Hub 中删除。 他们于 2021 年 8 月 21 日将这些映像移到了 Microsoft 容器注册表 (MCR)。

使用docker pull mcr.microsoft.com/dotnet/sdk:2.1 来代替 docker pull microsoft/dotnet。

MCR 上的 .NET 映像可从以下存储库获得：

• mcr.microsoft.com/dotnet/runtime-deps
• mcr.microsoft.com/dotnet/runtime
• mcr.microsoft.com/dotnet/aspnet
• mcr.microsoft.com/dotnet/sdk
