【异常解决】(一)解决docker报错failed to compute cache key: “...“ not found

本文章仅做记录异常用途

使用.net core右键LY.ProductSchedularService.Api自动生成dockerfile
并使用

docker build -t my_service .

构建镜像时，报错提示：
failed to compute cache key: “/App/LY/NetCore/LY.Common/LY.Common.csproj” not found: not found

DockerFile如下

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

#Depending on the operating system of the host machines(s) that will build or run the containers, the image specified in the FROM statement may need to be changed.

ENTRYPOINT ["dotnet", "LY.ProductSchedularService.Api.dll"]

原因分析：
Dockerfile不能跟LY.ProductSchedularService.Api项目同级的，因为该项目依赖引用了其他的2个项目，使用这个docker build命令会提示找不到另外的项目
解决方法：
把Dockerfile放于与App文件夹同级的目录下即可
