controller逻辑
通过reconcile 监听pod事件

打包运行controller镜像
make docker-build IMG=mikefan2019/noderequest-operator:v0.0.1

make docker-push IMG=mikefan2019/noderequest-operator:v0.0.1

make deploy IMG=mikefan2019/noderequest-operator:v0.0.1

查看crd 确定字段和数据正确
kubectl get noderequest -oyaml

kubectl get pod -n noderequest-operator-system

查看日志
kubectl logs -f noderequest-operator-controller-manager-5b4c8fd544-wjmmx -n noderequest-operator-system
