elasticsearch - 通过多节点集群设置时无法访问Kibana中的elasticsearch实例

Question

在通过docker compose由多节点集群设置时无法访问Kibana中的elasticsearch实例。
elasticsearch实例节点运行良好。
下面我分享了docker-compose.yaml和问题截图，有人可以帮我这个忙。
如果需要任何进一步的信息，请告诉我。
docker-compose.yml

您可以确认Elasticsearch节点可用吗？

curl -XGET http://elasticsearch:9200/_cat/nodes?v

并检查哪个节点作为主节点运行

curl -XGET http://elasticsearch:9200/_cat/master?v

也可能值得在您的docker-compose中将Elasticsearch添加为Kibana的依赖项，例如

kibana:
  image: docker.elastic.co/kibana/kibana:7.8.0
  container_name: kibana
  depends_on: elasticsearch
  environment:
    SERVER_NAME: kibana.local
    ELASTICSEARCH_URL: http://elasticsearch:9200
  ports:
    - '5601:5601'
  networks:
    - esnet
