amazon-web-services - 如何在快照中查找 Elasticsearch 索引？

Question

我有一个在 AWS 上运行的 Elasticsearch 集群，我有这样的快照

 {
     "snapshot": "2016-07-13_165430",
     "indices": [
        "analytical-2016-06-15",
        "analytical_2016-06-13",
        "analytical_2016-07-13",
        "operational-2016-06-15",
        "operational_2016-06-13",
        "operational_2016-07-13"
     ],
     "state": "SUCCESS",
     "start_time": "2016-10-10T23:54:33.705Z",
     "start_time_in_millis": 1476143673705,
     "end_time": "2016-10-10T23:54:44.893Z",
     "end_time_in_millis": 1476143684893,
     "duration_in_millis": 11188,
     "failures": [],
     "shards": {
        "total": 30,
        "failed": 0,
        "successful": 30
     }
  },
  {
     "snapshot": "2016-07-13_165546",
     "indices": [
        "analytical-2016-06-15",
        "analytical_2016-06-13",
        "analytical_2016-07-13",
        "operational-2016-06-15",
        "operational_2016-06-13",
        "operational_2016-07-13"
     ],
     "state": "SUCCESS",
     "start_time": "2016-10-10T23:55:48.808Z",
     "start_time_in_millis": 1476143748808,
     "end_time": "2016-10-10T23:55:52.420Z",
     "end_time_in_millis": 1476143752420,
     "duration_in_millis": 3612,
     "failures": [],
     "shards": {
        "total": 30,
        "failed": 0,
        "successful": 30
     }
  }

现在所有这些指数都与其他一些指数在线运行，例如:“分析-2016-06-15”，
"analytical_2016-06-13",
"analytical_2016-07-13",
“操作-2016-06-15”，
"operational_2016-06-13",
"operational_2016-07-13"
"operational_2016-09-13"
....

我需要检查我的索引是否已备份，如果已经备份，它存在于哪个快照中。

我怀疑@air 对查找 许多 快照中的哪些包含给定索引感兴趣；粘贴的示例只是快照历史记录的一个 View 。如果您在一段时间内拍摄每日快照，并且已添加/删除索引，手动搜索将是一件苦差事。

似乎没有用于“查找包含索引 operational_2021-06-10 的所有快照”的 API 调用，但这里有一个自动化选项:

 curl -XGET "http://cluster:9200/_snapshot/myrepo/*" |
   jq -c '.snapshots[] | select(.indices | index("operational_2021-06-10")) | { snapshot }'

{"snapshot":"daily-snap-2021.06.10-hjmskkjsryyq82asmxiuva"}
{"snapshot":"daily-snap-2021.06.11-eayyiiort0cx97r_jscara"}
{"snapshot":"daily-snap-2021.06.12-rmrsbmsespgf0_czu721hw"}
{"snapshot":"daily-snap-2021.06.13-meeoachori61w5r3n3qzaq"}
{"snapshot":"daily-snap-2021.06.14-espbnhuprcckqylk3xltwq"}
{"snapshot":"daily-snap-2021.06.15-sbosayasthinaudxaqw3pa"}
