官方文档
官方下载镜像

获取镜像

1 | docker pull docker.elastic.co/elasticsearch/elasticsearch:7.10.2

启动单节点集群

1 | docker run -p 9200:9200 --name=ela -d -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.10.2

登录集群

1 | docker exec -it ela bash

启动多个节点的集群
创建一个docker-compose.yml file:

version: '2.2'
services:es01:image: docker.elastic.co/elasticsearch/elasticsearch:7.10.2container_name: es01environment:- 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: -1hard: -1volumes:- data01:/usr/share/elasticsearch/dataports:- 9200:9200networks:- elastices02:image: docker.elastic.co/elasticsearch/elasticsearch:7.10.2container_name: es02environment:- 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: -1hard: -1volumes:- data02:/usr/share/elasticsearch/datanetworks:- elastices03:image: docker.elastic.co/elasticsearch/elasticsearch:7.10.2container_name: es03environment:- 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: -1hard: -1volumes:- data03:/usr/share/elasticsearch/datanetworks:- elasticvolumes:data01:driver: localdata02:driver: localdata03:driver: localnetworks:elastic:driver: bridge

执行如下命令启动集群

前台启动

1 | docker-compose up  

后台启动

1 | docker-compose up -d

停止集群

1 | docker-compose down

检查机器健康状态

1 | curl http://127.0.0.1:9200/_cat/health
