index lifecycle 索引生命周期管理

1.首先设置一个lifecycle policies

2.创建索引模板，在模板中绑定生命周期

PUT _template/logstash-tx
{
    "order" : 10,
    "version" : 60001,
    "index_patterns" : [
      "logstash-*"
    ],
    "settings" : {
      "index" : {
        "lifecycle" : {
          "name" : "logstash-tx"
        },
        "number_of_shards" : "1",
        "refresh_interval" : "5s"
      }
    },
    "mappings" : {
      "dynamic_templates" : [
        {
          "message_field" : {
            "path_match" : "message",
            "mapping" : {
              "norms" : false,
              "type" : "text"
            },
            "match_mapping_type" : "string"
          }
        },
        {
          "string_fields" : {
            "mapping" : {
              "norms" : false,
              "type" : "text",
              "fields" : {
                "keyword" : {
                  "ignore_above" : 256,
                  "type" : "keyword"
                }
              }
            },
            "match_mapping_type" : "string",
            "match" : "*"
          }
        }
      ],
      "properties" : {
        "@timestamp" : {
          "type" : "date"
        },
        "geoip" : {
          "dynamic" : true,
          "properties" : {
            "ip" : {
              "type" : "ip"
            },
            "latitude" : {
              "type" : "half_float"
            },
            "location" : {
              "type" : "geo_point"
            },
            "longitude" : {
              "type" : "half_float"
            }
          }
        },
        "@version" : {
          "type" : "keyword"
        }
      }
    },
    "aliases" : { }
  }

3.新建index并查看是否成功引用生命周期
