本文件使用nfs儲存，nfs的搭建參考文件：https://www.cnblogs.com/pgy674477230/p/16326880.html
建立pvc
cat nacos-pvc-headless.yml

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: nacos-pvc-headless
  namespace: test03
  annotations:
    pv.kubernetes.io/bind-completed: 'yes'
    pv.kubernetes.io/bound-by-controller: 'yes'
    volume.beta.kubernetes.io/storage-provisioner: k8s-sigs.io/nfs-subdir-external-provisioner
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 5Gi
  volumeName: pvc-770acf2a-b03b-463b-9b44-d8a90d8c6862
  storageClassName: managed-nfs-storage
  volumeMode: Filesystem

建立服務

cat nacos-service-headless.yml

apiVersion: v1
kind: Service
metadata:
  name: nacos-headless
  labels:
    app: nacos
  annotations:
    service.alpha.kubernetes.io/tolerate-unready-endpoints: "true"
spec:
  ports:
    - port: 8848
      name: server
      targetPort: 8848
    - port: 9848
      name: client-rpc
      targetPort: 9848
    - port: 9849
      name: raft-rpc
      targetPort: 9849
    ## 相容1.4.x版本的選舉埠
    - port: 7848
      name: old-raft-rpc
      targetPort: 7848
  clusterIP: None
  selector:
    app: nacos
 

使用nodeport提供外部web訪問 或者使用ingress，本文使用nodeport方式，建立暴露服務
cat nacos-web.yml

kind: Service
apiVersion: v1
metadata:
  name: nacos-web
  namespace: test03
spec:
  ports:
    - name: http
      protocol: TCP
      port: 8848
      targetPort: 8848
      nodePort: 31848
  selector:
    app: nacos
  clusterIP: 10.2.202.97
  clusterIPs:
    - 10.2.202.97
  type: NodePort
  sessionAffinity: None
  externalTrafficPolicy: Cluster

 

建立配置

cat nacos-cm.yml

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

建立StatefulSet 部署叢集

cat nacos-headless.yml

kind: StatefulSet
apiVersion: apps/v1
metadata:
  name: nacos
  namespace: test03
spec:
  replicas: 3
  selector:
    matchLabels:
