我的 Dockerfile 如下
My Dockerfile looks below

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

推荐答案
多阶段构建(添加了 FROM ... AS ... 语法以及多个 FROM 行)需要 17.05 或更高版本.您需要升级您的 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，请参阅:https://docs.docker.com/develop/develop-images/multistage-build/
