docker 运行elasticsearch 集群-Go服务器开发

要在 Docker 中运行 Elasticsearch 集群，您需要使用 Docker Compose。以下是步骤：

首先，创建一个新的目录，例如 “elasticsearch”，并在该目录中创建一个新文件 docker-compose.yml。
在 docker-compose.yml 文件中添加以下内容：

version: '3'
services:
  es01:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.5.0
    container_name: es01
    environment:
      - node.name=es01
      - cluster.name=es-docker-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:
      - datavolume:/usr/share/elasticsearch/data
    ports:
      - 9200:9200
    networks:
      - esnet
  es02:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.5.0
    container_name: es02
    environment:
      - node.name=es02
      - cluster.name=es-docker-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:
      - datavolume:/usr/share/elasticsearch/data
    networks:
      - esnet
  es03:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.5.0
    container_name: es03
    environment:
      - node.name=es03
      - cluster.name=es-docker-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:
      - datavolume:/usr/share/elasticsearch/data
    networks:
      - esnet
