Thank you very much for your work. I have kcloude (192.168.1.200) and kedge1 (192.168.1.201). I want to know how to debug my mapper because I can't guarantee that every line of code is correct. For example, I use kubedege1.17, and I want to generate a mapper for LED lights. Should I clone kubeedge 1.17 to kedge1 and then use make template to generate a template, add relevant files, and then use Goland to debug my code. Is it impossible to debug in kcloude, only deploy?
The code I used is
