FROM mcr.microsoft.com/dotnet/core/sdk:2.2 AS build
WORKDIR /app

COPY . /app
WORKDIR /app/base/curseIS.STS.Identity

RUN ln -s /usr/lib64/libgdiplus.so /usr/lib/gdiplus.dll
RUN ln -s /usr/lib64/libgdiplus.so /usr/lib64/gdiplus.dll

#--from=build就是上一个构建阶段. 这行表示把上个阶段的out文件夹下内容都copy到当前目录下

ENTRYPOINT ["dotnet", "curseIS.STS.Identity.dll"]
