我对Elasticsearch的索引模板有一个小问题。
这是我的模板：
curl -X GET "localhost:9200/_cat/templates?v&s=name"
logstash [logstash-*] 0 60001
logstash-index-template [.logstash] 0
logstash-index-template：
curl -X GET "localhost:9200/_template/logstash-index-template"
{"logstash-index-template":{"order":0,"index_patterns":[".logstash"],"settings":{"index":{"number_of_shards":"1","auto_expand_replicas":"0-1","codec":"best_compression"}},"mappings":{"doc":{"_meta":{"logstash-version":"6.3.1"},"dynamic":"strict","properties":{"description":{"type":"text"},"last_modified":{"type":"date"},"pipeline_metadata":{"properties":{"version":{"type":"short"},"type":{"type":"keyword"}}},"pipeline":{"type":"text"},"pipeline_settings":{"dynamic":false,"type":"object"},"username":{"type":"keyword"},"metadata":{"type":"object","dynamic":false}}}},"aliases":{}}}
我想更新此模板，以便删除auto_expand_replicas并添加number_of_replicas：0。
curl -X PUT "localhost:9200/_template/logstash-index-template" -H 'Content-Type: application/json' -d '{"logstash-index-template":{"order":0,"index_patterns":[".logstash"],"settings":{"index":{"number_of_shards":"1","number_of_replicas":"0","codec":"best_compression"}},"mappings":{"doc":{"_meta":{"logstash-version":"6.3.1"},"dynamic":"strict","properties":{"description":{"type":"text"},"last_modified":{"type":"date"},"pipeline_metadata":{"properties":{"version":{"type":"short"},"type":{"type":"keyword"}}},"pipeline":{"type":"text"},"pipeline_settings":{"dynamic":false,"type":"object"},"username":{"type":"keyword"},"metadata":{"type":"object","dynamic":false}}}},"aliases":{}}}'
这是个好方法吗？ 我已经通过此调用更新了现有索引：
curl -X PUT "localhost:9200/_settings" -H 'Content-Type: application/json' -d'{ "index" : { "number_of_replicas" :0 }}'
我在Elasticsearch网站上找不到完整的文档，因此如果有人已经做过，请在这里询问：）
谢谢，祝您有美好的一天！
