1、准备环境

一台安装了docker的机器(并且安装docker-compose)
es版本：elasticsearch:8.6.2(使用的es版本)
kibana:8.6.2

以上都是在ubuntu22.04下进行的安装

2、获取镜像

docker pull elasticsearch:8.6.2
docker pull kibana:8.6.2

上诉拉取镜像可能会比较慢，请耐心等待

3、docker-compose编排

创建一个elasticstack目录，在目录下分别创建node1,node2,node3 三个文件夹，作为三个节点的挂载目录(然后根据需求在nodex下创建data,conf等目录挂载容器内的es相关文件夹\文件)

3.1、编写docker-compose.yml配置

version: '3.7'
services:
  es01:
    image: ${image}
    container_name: es01
    ports:
      - "9200:9200"
      - "9300:9300"
    environment:
      node.name: es01
      cluster.name: docker-cluster 
      discovery.seed_hosts: es01,es02,es03
      cluster.initial_master_nodes: es01,es02,es03
      ES_JAVA_OPTS: -Xms512m -Xmx512m
      xpack.security.enabled: false # es8引入https,为了开发方便关闭
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - /home/zt/elasticstack/node1/data:/usr/share/elasticsearch/data
    networks:
      - es-net

  es02:
    image: ${image}
    container_name: es02
    ports:
      - "9201:9200"
      - "9301:9300"
    environment:
      node.name: es02
      cluster.name: docker-cluster
      discovery.seed_hosts: es01,es02,es03
      cluster.initial_master_nodes: es01,es02,es03

    volumes:

    networks:
      - es-net

  es03:
    image: ${image}
    container_name: es03
    ports:
      - "9202:9200"
      - "9302:9300"
    environment:

      hard: -1
  volumes:

  kibana:
    image: ${image_kibana}
    container_name: kibana
    depends_on:
      - es01
      - es02
      - es03
    environment:
      SERVERNAME: kibana

      ELASTICSEARCH_HOSTS: '["http://es01:9200","http://es02:9200","http://es03:9200"]'
