Debug in multi-nodes environment


Hi guys, I have built K8S multi-nodes environment.
I would like to know the workflow of each service (API server, scheduler, kubelet…). Although there are some logs in var/log and I have tried to increase log level in config file from etc/kubernetes, it’s not enough information for me to trace them. It will be better if I can debug them. Have you guys any solutions?

p/s: Actually, I have tried to deploy a single-node environment which was built from source code, then debug it with GoLand IDE, it seems fine (except kubelet has got trouble).
