I am a beginner to learn gitlab CI/CD and doing some projects related to it. I have a trouble when using OpenFaaS and build a large number of function.I want to use CI/CD to automatically build functions that have updates, remain functions are not, but I don't know how to get name of specific folder or directory changed in my source to build corresponding functions.
So I wonder if we have a way to get name of specific directory changed in Gitlab CI/CD? Or another tools CI/CD can do that?
