如果我没猜错的话，你想创建3个节点的ElasticSearch和千花。下面我提供了一个docker-compose文件，它将帮助你创建3个节点的ElasticSearch和千花集群。

version: "3"
services:
  kibana:
    container_name: kibana
    image: docker.elastic.co/kibana/kibana:7.16.3
    environment:
      SERVER_NAME: kibana
      ELASTICSEARCH_HOSTS: http://127.0.0.1:9200
    ports:
      - 127.0.0.1:5601:5601
    networks:
      - esnet
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.16.3
    container_name: elasticsearch
    environment:
      - cluster.name=docker-cluster
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - "-Des.logger.level=DEBUG"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - esdata1:/usr/share/elasticsearch/data
    ports:
      - 127.0.0.1:9200:9200
    networks:
      - esnet
  elasticsearch2:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.16.3
    container_name: elasticsearch2
    environment:
      - cluster.name=docker-cluster
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - "discovery.zen.ping.unicast.hosts=elasticsearch"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - esdata2:/usr/share/elasticsearch/data
    networks:
      - esnet
  elasticsearch3:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.16.3
    container_name: elasticsearch3
    environment:
      - cluster.name=docker-cluster
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - "discovery.zen.ping.unicast.hosts=elasticsearch"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - esdata3:/usr/share/elasticsearch/data
    networks:
      - esnet

volumes:
  esdata1:
    driver: local
  esdata2:
    driver: local
  esdata3:
    driver: local

networks:
  esnet:

这将创建3个命名卷（esdata 1、esdata 2、esdata 3），这些卷将在/var/lib/docker/volumes/处创建
如果你遇到任何问题，请告诉我。
