docker的问题

Question

以下是我的dockerfile：

FROM mcr.microsoft.com/dotnet/aspnet:5.0 AS base
WORKDIR /app
EXPOSE 8080/tcp
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build
WORKDIR /src
COPY ["ProductDirectory.csproj", "."]
RUN dotnet restore "./ProductDirectory.csproj"
COPY . .
WORKDIR "/src/."
RUN dotnet build "ProductDirectory.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "ProductDirectory.csproj" -c Release -o /app/publish
EXPOSE 8080/tcp

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

在DockerFile中使用多个stage是个好主意。但是您应该小心这一点，因为Docker只接收dockerfile的最新部分，在您的情况下，它只接收这一部分：

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

您没有定义应用程序的端口。要解决此问题，只需添加公开端口并为此节指定您的端口，如下所示：

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
EXPOSE 8080
ENTRYPOINT ["dotnet", "ProductDirectory.dll"]

我希望这能帮助你解决你的问题。
