 　　docker-compose版本

# docker-compose version
docker-compose version 1.18.0, build 8dd22a9
docker-py version: 2.6.1
CPython version: 3.6.8
OpenSSL version: OpenSSL 1.0.2k-fips  26 Jan 2017

 　　系统信息

# cat /etc/red
redhat-release       redis.conf           redis-sentinel.conf  
[root@local-k8s-master elasticsearch]# cat /etc/redhat-release 
CentOS Linux release 7.8.2003 (Core)

 　　创建docker-compose文件夹

mkdir /elasticsearch/

 　　创建elasticsearch数据文件夹

mkdir  /usr/share/elasticsearch/data/

 　　设置sysctl参数

echo "vm.max_map_count=655360">>/etc/sysctl.conf
sysctl -p

 　　PS：不设置启动elasticsearch报错

　　创建docker-compos配置文件

# cat /elasticsearch/docker-compose.yml 
version: '2.2'
services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:6.6.2
    container_name: elasticsearch
    environment:
      - cluster.name=docker-cluster
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - esdata1:/usr/share/elasticsearch/data
    ports:
      - 9200:9200
    networks:
      - esnet
  elasticsearch2:
    image: docker.elastic.co/elasticsearch/elasticsearch:6.6.2
    container_name: elasticsearch2
    environment:
      - cluster.name=docker-cluster
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      #设置集群master节点是elasticsearch
      - "discovery.zen.ping.unicast.hosts=elasticsearch"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - esdata2:/usr/share/elasticsearch/data
    networks:
      - esnet
    
  kibana:
    image: docker.elastic.co/kibana/kibana:6.6.2
    container_name: kibana
    environment:
      - ELASTICSEARCH_HOSTS="http://elasticsearch:9200"
    ports:
      - 5601:5601
    networks:
      - esnet
 
volumes:
  esdata1:
    driver: local
  esdata2:
    driver: local

networks:
  esnet:

 　　启动

 cd /elasticsearch/
#-d参数后台启动
 docker-compose up -d

 　　查看启动

# docker-compose ps
     Name                   Command               State                Ports              
------------------------------------------------------------------------------------------
elasticsearch    /usr/local/bin/docker-entr ...   Up      0.0.0.0:9200->9200/tcp, 9300/tcp
elasticsearch2   /usr/local/bin/docker-entr ...   Up      9200/tcp, 9300/tcp              
kibana           /usr/local/bin/kibana-docker     Up      0.0.0.0:5601->5601/tcp          

 　　对应主机启动了端口9200 5601

 　　PS：本次测试es两个节点挂载的数据目录是一样的
