使用

1. 安裝 docker 和 docker-compose
2. 執行命令 docker-compose up -d
3. 打開 chrome 瀏覽器的插件 ElasticSearch Head, 效果如下圖

本例子選擇了 es 和 es1 爲 master
若想方便看日誌, 也可將 logs 掛載出來, 例如在 docker-compose.yml 中 es 的 volumes 加上
- ./logs/es/:/usr/share/elasticsearch/logs/:rw
同理 data 掛載出來可加上
- ./data/es/:/usr/share/elasticsearch/data/:rw
