用Curator重新索引所有ElasticSearch？

Question

Is there a Recipe out there to Reindex all ElasticSearch Indices with Curator?

I'm seeing that it can Reindex a set of indices into one (Daily to Month use case), however I don't see anything that would suggest it could easily apply a new mapping file to every Elastic Index.

I'm taking a guess I'll need to write a wrapper script around Curator to grab index names and feed them into Curator.

I don't know if I got you right as you mentioned reindexing and mapping changes...

If you want to set/update a mapping in a collection of indices and if you know the indices to update by name (or pattern), you are able to apply the same mapping or a mapping change at once with https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-put-mapping.html#_multi_index_2

For reindexing, there is no way to specify multiple source/target pairs at once but you can split one index into many. But as you sugessted, you can use subsequent calls to the reindex api.

BTW: The reindex api does not copy the settings nor mappings from the source into the destination index. You need to handle it by yourself, maybe using https://www.elastic.co/guide/en/elasticsearch/reference/6.4/indices-templates.html
