docker-compose 编排es

要使用 docker-compose 编排 Elasticsearch 集群，可以参考以下步骤：

1. 创建一个 docker-compose.yml 文件，定义 Elasticsearch 服务的配置。例如：

version: '3'
services:
  es01:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.14.0
    container_name: es01
    environment:
      - node.name=es01
      - cluster.name=my-es-cluster
      - discovery.seed_hosts=es02,es03
      - cluster.initial_master_nodes=es01,es02,es03
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - esdata01:/usr/share/elasticsearch/data
    ports:
      - 9200:9200
    networks:
      - esnet
  es02:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.14.0
    container_name: es02
    environment:
      - node.name=es02
      - cluster.name=my-es-cluster
      - discovery.seed_hosts=es01,es03
      - cluster.initial_master_nodes=es01,es02,es03
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - esdata02:/usr/share/elasticsearch/data
    networks:
      - esnet
  es03:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.14.0
    container_name: es03
    environment:
      - node.name=es03
      - cluster.name=my-es-cluster
      - discovery.seed_hosts=es01,es02
      - cluster.initial_master_nodes=es01,es02,es03
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - esdata03:/usr/share/elasticsearch/data
    networks:
      - esnet

volumes:
  esdata01:
  esdata02:
  esdata03:

networks:
  esnet:

2. 在终端中进入 docker-compose.yml 文件所在的目录，运行以下命令启动 Elasticsearch 集群：

docker-compose up -d

3. 等待一段时间，直到 Elasticsearch 集群启动完成。可以通过以下命令查看集群状态：

curl http://localhost:9200/_cat/health?v

输出结果应该类似于：

epoch      timestamp cluster       status node.total node.data shards pri relo init unassign pending_tasks max_task_wait_time active_shards_percent
1630459477 08:31:17  my-es-cluster green           3         3     15  15    0    0        0             0                  -                100.0%
