分别创建clusterip和nodeport service

apiVersion: v1
kind: Service
metadata:
  name: nacos
  namespace: pro-nacos
  labels:
    app: nacos
  annotations:
    service.alpha.kubernetes.io/tolerate-unready-endpoints: "true"
spec:
  ports:
  - protocol: TCP
    port: 8848
    targetPort: 8848
    nodePort: 31248
    name: nacos-http
  - protocol: TCP
    port: 9848
    targetPort: 9848
    name: raft-rpc
    nodePort: 32248
  selector:
    app: nacos
  type: NodePort
---
apiVersion: v1
kind: Service
metadata:
  name: nacos-headless
  namespace: pro-nacos
  labels:
    app: nacos-headless
spec:
  type: ClusterIP
  clusterIP: None
  ports:
    - port: 8848
      name: server
      targetPort: 8848
    - port: 9848
      name: client-rpc
      targetPort: 9848
    - port: 9849
      name: raft-rpc
      targetPort: 9849
    - port: 7848
      name: old-raft-rpc
      targetPort: 7848
  selector:
    app: nacos

创建配置文件

apiVersion: v1
kind: ConfigMap
metadata:
  name: nacos-cm
  namespace: pro-nacos
data:
  mysql.db.host: "10.156.156.13"
  mysql.db.name: "nacos_config"
  mysql.port: "3306"
  mysql.user: "nacos"
  mysql.password: "nacos"

部署nacos集群

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: nacos
  namespace: pro-nacos
spec:
  serviceName: nacos-headless
  replicas: 3
  template:
