Nginx + Docker 多阶段构建的部署学习

　　前几天部署了一个网站，原来我一直是发布完成之后，通过ftp把文件上传上去，有几个大佬给我说了多阶段构建，此时我就不需要发布再搞了，直接将项目添加docker支持。

#See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base
WORKDIR /app
EXPOSE 80

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build
WORKDIR /src
COPY ["amusinghoS.App/amusinghoS.App.csproj", "amusinghoS.App/"]

RUN dotnet restore "amusinghoS.App/amusinghoS.App.csproj"
COPY . .
WORKDIR "/src/amusinghoS.App"
RUN dotnet build "amusinghoS.App.csproj" -c Release -o /app/build

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

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

其中最重要的就是那几个COPY ，只要是和你这个项目有依赖的，统统打包，构建成一个镜像。
