也称为INTERNAL-IP,这是各Node的物理网卡（也可能是VPS的虚拟网卡）的IP地址的映射地址（Host IP的映射IP），是ECS的私有IP地址，也可以称为Node IP 这部分信息可以通过kubectl get node -o wide获取得到。
POD IP
它是pod网络的IP地址，是每个POD分配的虚拟IP,可以使用 kubectl get pod -o wide来查看。
CLUSTER-IP
它是Service的地址,是一个虚拟地址（无法ping），是使用kubectl create时，–port 所指定的端口绑定的IP,各Service中的pod都可以使用CLUSTER-IP:port的方式相互访问（当然更应该使用ServiceName:port的方式）,可以使用‘kubectl get svc’进行查看。

thirdwork
请将第一次作业的程序通过Deployment或StatefuleSet的方式部署在Kubernetes上，作业环境可选择minikube（https://mikinikube.sigs.k8s.io）或kind（https://kind.sigs.k8s.io/） 请提交对应的Deployment/StatefulSet定义文件（yaml格式），以及相应的Service定义文件（yaml格式）

NODE IP
也称为INTERNAL-IP,这是各Node的物理网卡（也可能是VPS的虚拟网卡）的IP地址的映射地址（Host IP的映射IP），是ECS的私有IP地址，也可以称为Node IP 这部分信息可以通过kubectl get node -o wide获取得到。

PORT
targetPort
它是Pod内部容器的端口，比如tomcat是8080，PODIP:targetPort，构成了EndPoint
port
它是Service的虚拟端口，对targetPort进行映射。CLUSTER-IP:port，构成了微服务地址。
nodePort
它是集群对外暴露的端口，NODEIP:nodePort，构成对外访问的地址
运行说明
kind create cluster 创建cluster docker build -t pet-server:1.0 . 创建docker镜像 kind load docker-image pet-server:1.0 加载镜像 kubectl apply -f deployment.yaml kubectl apply -f service.yaml kubectl get pods -o wide kubectl logs pod-name 如果没有正常启动,查看日志寻找错误 kubectl get node -o wide 查看对应的INTERNAL-IP,将client的访问目标设置为NODE_INTERNAL-IP:NodePORT go run client/client.go
