Docker-compose 建立ELK集群的实现方法

全部编排文件和配置文件可以访问我的 Github ，大家只要修改配置文件中的路径即可快速搭建一个3实例的ES集群和一个Kibana实例。

规划

计划创建3个ES实例组成一个集群，同时创建一个Kibana实例连接该集群。每个ES实例使用本地配置文件，方便配置文件的保存和版本管理。Kibana的配置文件也放在本地，通过文件映射的方式挂载到容器内。

总的目录结构如下：

$ tree.├── docker-compose.yml├── kibana.yml├── node1│ └── es1.yml├── node2│ └── es2.yml└── node3 └── es3.yml3 directories, 5 files

编排文件

主要的编排文件是 docker-compose.yml

ES配置文件只选取了一个示例如下：
