    fileRealm:
    - secretName: kubesphere-elasticsearch-realm-secret # 通过Kubernetes secret添加自定义用户和密码
  http:
    tls:
      selfSignedCertificate:
        disabled: true # 关闭tls
  nodeSets:
  - name: lit 
    count: 3 # 部署集群节点数
    config:
      node.store.allow_mmap: false
    volumeClaimTemplates: # 存储配置
