可以使用IP連接到elasticsearch窗格但不使用窗口名稱

Question

我已經成功地在IP（硬編碼地址：端口）上指定我的elasticsearch.yaml文件中的主機，但我被告知這是不好的做法。我正在嘗試切換到僅使用ES羣集的pod名稱，現在沒有發現/使用pod作爲主羣集。我對所有3個吊艙，我安裝具有以下規格一elasticsearch.yml configMap：

cluster.name: elasticsearch-logs 
    node.name: ${HOSTNAME} 
    node.master: true 
    node.data: true 
    network.host: _local_ 
    transport.tcp.port: 9300 
    http.port: 9200 
    bootstrap.memory_lock: false 
    xpack.security.enabled: false 
    discovery.zen.minimum_master_nodes: 2 
    discovery.zen.ping.unicast.hosts: ["es-0:9300", "es-1:9300", "es-2:9300"] 

隨着這個我有2個服務。一個是無頭服務，另一個是ClusterIP。

apiVersion: v1 
kind: Service 
metadata: 
    name: elasticsearch-svc 
    labels: 
    component: elasticsearch 
    role: master 
spec: 
    selector: 
    component: elasticsearch 
    role: master 
    ports: 
    - name: transport 
    port: 9300 
    targetPort: 9300 
    clusterIP: None 


apiVersion: v1 
kind: Service 
metadata: 
    name: elasticsearch-discovery 
    labels: 
    component: elasticsearch 
    role: master 
spec: 
    selector: 
    component: elasticsearch 
    role: master 
    ports: 
    - name: transport 
    port: 9300 
    protocol: TCP 

而且在創建該ES莢我有口規格主要StatefulSet文件：

ports: 
     - containerPort: 9200 
      name: db 
      protocol: TCP 
     - containerPort: 9300 
      name: transport 
      protocol: TCP 

我試圖讓所有3個莢作爲主（和數據/客戶端）。當我看着吊艙日誌之一（這裏ES-0）創建我的服務/ statefulsets我看到下面的重複錯誤後：

我仍然能夠在node-ip:node-port達到通過瀏覽器elasticsearch但我得到503錯誤一旦我嘗試做/_cluster/state

我相信我有一個端口的「網絡」端的錯誤，但我不確定在哪裏。我應該看什麼？謝謝！

您需要使用完整的DNS名稱連接：

es-0.elasticsearch-internal:9300
