• 参考：https://www.elastic.co/guide/en/elasticsearch/client/curator/current/installation.html

2, 配置使用

配置

• 关闭索引，action.yaml 加上 ignore_empty_list: True, 防止条件不满足时报错，导致任务不能继续执行
• 删除索引，action.yaml 加上continue_if_exception: True , 防止删除索引报错，导致任务不能继续执行
• action.yaml 配置参考：
  action-close模板：https://www.elastic.co/guide/en/elasticsearch/client/curator/current/ex_close.html
• 索引名匹配-正则参考：https://www.elastic.co/guide/en/elasticsearch/client/curator/current/filtertype_pattern.html
