Hi All,
I am kind of stuck with kubectl get nodes returning empty resource.
kubectl version :
kubectl version
Client Version: version.Info{Major:“1”, Minor:“12”, GitVersion:“v1.12.2”, GitCommit:“17c77c7898218073f14c8d573582e8d2313dc740”, GitTreeState:“clean”, BuildDate:“2018-10-30T21:39:38Z”, GoVersion:“go1.11.1”, Compiler:“gc”, Platform:“darwin/amd64”}
Server Version: version.Info{Major:“1”, Minor:“12”, GitVersion:“v1.12.3”, GitCommit:“435f92c719f279a3a67808c80521ea17d5715c66”, GitTreeState:“clean”, BuildDate:“2018-11-26T12:46:57Z”, GoVersion:“go1.10.4”, Compiler:“gc”, Platform:“linux/amd64”}
I enabled debug and saw that it runs the get nodes api. when i run get nodes api , this is what the api server returns.
