docker搭建3节点elastics8.x集群七第七公社

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"
