Debugging Kubernetes (Delve and Goland)

1. Build from source

CD Gopath

mkdir K8s.io

CD K8s.io

git clone https://github.com/kubernetes/kubernetes.git

Note:make the location of Sure source code at $GOPATH/k8s.io/kubernetes

Example:

Gopath/src/github.com/xuchencn/xxxx

Gopath/src/k8s.io/kubernetes

CD $GOPATH/k8s.io/kubernetes

Make

After make find Cmds on "_output/bin/"

2.Install Delve

Follow the delve ' s toturial to install delve

After the install you can debugging use delve or use Goland

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 would 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
