本文档展示了如何使用Docker部署Elasticsearch集群，包括配置镜像、设置网络、环境变量、资源限制，并通过Docker Compose进行服务定义。同时，详细说明了如何同步配置Kibana，确保与Elasticsearch版本匹配，用于数据可视化。集群包含两台节点，每台节点分配了特定的CPU和内存资源，并设置了重启策略。最后，提到了Kibana的端口映射和网络配置，以及启动时可能遇到的问题和解决方法。

本次使用镜像为官方6.x镜像

容器版本为

Docker version 18.09.4, build d14af54266

创建目录作为数据存储地址

- /home/dockeres/db
- /home/dockeres/db/log

#启动时可能报错

echo “vm.max_map_count=655300” > /etc/sysctl.conf

sysctl -p

swarm elasticsearch 启动成功

公司用kibana 来做elasticsearch mapping 创建

接下来构建 kibana

version: ‘3.3’
services:
kiban:
image: docker.elastic.co/kibana/kibana:6.4.2
ports:
- 5603:5601
networks:
- es
environment:
- ELASTICSEARCH_URL=http://es:9200
configs:
- source: kibana.yml
target: /usr/share/kibana/config/kiban.yml
deploy:
restart_policy:
condition: on-failure
replicas: 1
placement:
constraints:
- node.hostname==slaver-01
endpoint_mode: vip
resources:
limits:
cpus: ‘2’
memory: 1500M
reservations:
cpus: ‘0.5’
memory: 800M
networks:
es:
external: true

configs:
kibana.yml:
file: ./kibana.yml

kibana yml文件

[root@master docker]# cat kibana.yml
server.name: kibana
server.host: “0.0.0.0”
elasticsearch.url: http://es:9200
#elasticsearch.username: elastic
#elasticsearch.password: acl123456
xpack.monitoring.ui.container.elasticsearch.enabled: true
xpack.security.enabled: false

注意kibana 版本一定要和es版本一致
