1. Build from source
cd GOPATH
mkdir k8s.io
cd k8s.io
git clone https://github.com/kubernetes/kubernetes.git

3.Debugging by Goland
Example by apiserver
cd $GOPATH/src/k8s.io/kubernetes/cmd/kube-apiserver/
$GOPATH/bin/dlv debug --headless --listen=:2345 --api-version=2 -- k8s.io/kubernetes/cmd/kube-apiserver/apiserver.go --etcd-servers http://localhost:2379
After the command delve will output a "debug" file in current directory and listen on 2345 port
Open Goland create new remote debug
Don‘t forget create breakingpoints before debugging
