无法建立：解析参考错误：“ microsoft / dotnet：2.1-runtime AS base”；不是有效的存储库/标签： [英] Failed to build: Error parsing reference: "microsoft/dotnet:2.1-runtime AS base" is not a valid repository/tag:

问题描述

使用.net core为控制台应用程序构建docker时出现以下错误。

I got the below error when build docker for console application using .net core.

步骤1/15：来自microsoft / dotnet ：2.1-runtime AS base
解析引用错误： microsoft / dotnet：2.1-runtime AS base不是有效的存储库/标签：无效的引用格式

Step 1/15 : FROM microsoft/dotnet:2.1-runtime AS base Error parsing reference: "microsoft/dotnet:2.1-runtime AS base" is not a valid repository/tag: invalid reference format

我的Dockerfile如下

My Dockerfile looks below

FROM microsoft/dotnet:2.1-sdk AS build
WORKDIR /src
COPY ConsoleApp2/ConsoleApp2.csproj ConsoleApp2/
RUN dotnet restore ConsoleApp2/ConsoleApp2.csproj
COPY . .
WORKDIR /src/ConsoleApp2
RUN dotnet build ConsoleApp2.csproj -c Release -o /app

FROM build AS publish
RUN dotnet publish ConsoleApp2.csproj -c Release -o /app

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "ConsoleApp2.dll"]

我的Docker版本是

My docker version is

Docker版本17.03.1-ce-rc1，内部版本3476dbf

Docker version 17.03.1-ce-rc1, build 3476dbf

有人可以建议我在这方面做错了什么。
预先感谢。

Can some one suggest what I am doing wrong in this. Thanks in advance.

推荐答案

多阶段构建（其中添加了 FROM .. AS ... 语法以及多条 FROM 行）需要17.05或更高版本。您需要升级docker服务器。

Multi-stage builds (which added the FROM ... AS ... syntax along with multiple FROM lines) require 17.05 or newer. You'll need to upgrade your docker server.

有关多阶段构建的更多详细信息，请参见：> https://docs.docker.com/develop/develop-images/multistage-build/
