为什么我们要构建和发布为两个步骤,而发布也要构建?

dockerfile visual-studio-2017 asp.net-core .net c#

抱歉,如果这是一个愚蠢的问题,那么为什么dockerfile在构建发布时还包含构建和发布步骤?

以下dockerfile是在我的Web应用程序中创建的:

FROM microsoft/dotnet:2.1-aspnetcore-runtime AS base
WORKDIR /app
EXPOSE 80

FROM microsoft/dotnet:2.1-sdk AS build
WORKDIR /src
COPY ["WebApplication1/WebApplication1.csproj", "WebApplication1/"]
RUN dotnet restore "WebApplication1/WebApplication1.csproj"
COPY . .
WORKDIR "/src/WebApplication1"
RUN dotnet build "WebApplication1.csproj" -c Release -o /app

FROM build AS publish
RUN dotnet publish "WebApplication1.csproj" -c Release -o /app

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "WebApplication1.dll"]

当我们 在我们的代码中添加一些引用/服务/实体 当部分完成的代码需要调试时。在调试模式下,每次需要用build编译时,当代码100%完成时,不需要编译。通过发布直接生成。

根据这本书 .NET Microservices: Architecture for Containerized .NET Applications (Microsoft EBook) , 第一个构建指令是冗余的 因为publish指令也会生成,它就在第一条生成指令之后。第94(86)页,第10行。

这是这本书的一个简短摘录:
