创建索引策略及如何关联索引模板

一、在dev tools命令窗口输入 _cat/plugins查看es集群安装的插件列表

如果安装了opendistro_index_management这个插件，就可以支持索引管理功能，可以创建索引策略。

二、下面是创建索引策略的步骤

三、下面是定义索引策略的模板内容：

{
    "policy": {
        "policy_id": "warm_30d_delete_workflow",
        "description": "warm_30d_delete_workflow",
        "last_updated_time": 1660548785549,
        "schema_version": 1,
        "error_notification": null,
        "default_state": "warm",
        "states": [
            {
                "name": "warm",
                "actions": [],
                "transitions": [
                    {
                        "state_name": "delete",
                        "conditions": {
                            "min_index_age": "30d"
                        }
                    }
                ]
            },
            {
                "name": "delete",
                "actions": [
                    {
                        "delete": {}
                    }
                ],
                "transitions": []
            }
        ]
    }
}

四、关联索引模板

{
    "order" : 0,
    "version" : 60001,
    "index_patterns" : [
      "*"
    ],
    "settings" : {
      "index" : {
        "highlight" : {
          "max_analyzed_offset" : "10000000"
        },
        "routing" : {
          "allocation" : {
            "total_shards_per_node" : "-1"
          }
        },
        "opendistro" : {
          "index_state_management" : {
            "policy_id" : "hot_warm_delete_workflow"
          }
        },
        "refresh_interval" : "5s",
        "number_of_shards" : "1",
        "number_of_replicas" : "1"
      }
    },
    "mappings" : {
     ........}
........
