如何在deploy函数时设定层？

每次deploy的时候层的设定会清空，文档中貌似没有如何配置的相关说明

Start by reproducing a deploy and checking how the function's layer configuration is supplied and whether it is cleared afterward. The issue names no files, tests, or entry points, so first locate the deployment and layer-configuration documentation or entry point. Done means the supported configuration is documented and layers remain configured after deployment.
