.net 5 的 Docker 镜像 [英] Docker image for .net 5

问题描述

通常我将以下图像用于 .net core 3.1 并且它工作正常.

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base从 mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS 构建

出于实验原因，我开始了一个新的 .net 5 项目，并使用以下内容创建了 dockerfile

FROM mcr.microsoft.com/dotnet/core/aspnet:5.0-buster-slim AS base从 mcr.microsoft.com/dotnet/core/sdk:5.0-buster AS 构建

并有以下问题:

 =>错误 [内部] 加载 mcr.microsoft.com/dotnet/core/sdk:5.0-buster 0.2s 的元数据=>错误 [内部] 加载 mcr.microsoft.com/dotnet/core/aspnet:5.0-buster-slim 0.2s 的元数据=>从 mcr.microsoft.com/dotnet/core/sdk:5.0-buster 0.0s 取消 [build 1/7]=>=>解析 mcr.microsoft.com/dotnet/core/sdk:5.0-buster 0.0s=>[内部] 加载构建上下文 0.0s=>错误 [base 1/2] 来自 mcr.microsoft.com/dotnet/core/aspnet:5.0-buster-slim 0.0s=>=>解析 mcr.microsoft.com/dotnet/core/aspnet:5.0-buster-slim

图像描述 引用.

Typically I use following images for .net core 3.1 and it works fine.

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base
FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build

I have for experimental reason started a new .net 5 project and created dockerfile with following

FROM mcr.microsoft.com/dotnet/core/aspnet:5.0-buster-slim AS base 
FROM mcr.microsoft.com/dotnet/core/sdk:5.0-buster AS build

and have following issue:

 => ERROR [internal] load metadata for mcr.microsoft.com/dotnet/core/sdk:5.0-buster                           0.2s
 => ERROR [internal] load metadata for mcr.microsoft.com/dotnet/core/aspnet:5.0-buster-slim                   0.2s

 => => resolve mcr.microsoft.com/dotnet/core/aspnet:5.0-buster-slim

解决方案

As I read here, it is changed to:

FROM mcr.microsoft.com/dotnet/aspnet:5.0-buster-slim AS base
FROM mcr.microsoft.com/dotnet/sdk:5.0-buster-slim AS build

It is also mentioned on the docker hub with more info:

As part of the .NET 5.0 release, all .NET Docker images (including .NET Core 2.1 and 3.1) have transitioned to a new set of Docker repositories described below. Updates will continue to be made to supported tags in the old repository locations for backwards compatibility. Please update any repository references to these new names. For more information see the .NET 5.0 repository rename announcement.
