一、k8s节点及nacos库

master:192.168.91.166

node2:192.168.91.167

node3:192.168.91.168

K8s 集群：1 主 2 节点（k8s-master:192.168.91.166、node2:167、node3:168）
Nacos 镜像：swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/nacos/nacos-server:latest

二、创建nacos集群

1、创建命名空间

 kubectl create namespace nacos-cluster

 2、创建nocos  PV

##创建本地PV存储
kubectl apply -f nacos-pv.yaml

####查看 kubectl get pv

hostPath:
path: /data/nacos/log2

3、创建nocos  StatefulSet

nacos-cluster.yaml（无头 Service + StatefulSet 集群核心）

 3.1、 创建本地StatefulSet

##创建本地StatefulSet
kubectl apply -f nacos-cluster.yaml

####查看 kubectl get pvc,pod,svc -n  nacos-cluster

kubectl get pvc,pod ,svc -n  nacos-cluster

 3.2、 nacos-cluster.yaml内容

# 无头服务：集群内部节点通信专用
apiVersion: v1
kind: Service
