Hi All ,
Please help me with the CURL command to change the "number\_of\_replicas" on Elasticsearch 5.0, the below command is not currently working with same-
curl -XPUT [http://localhost:9200/\_settings](http://localhost:9200/_settings) -d {"number\_of\_replicas":0}
Please suggest if anything missing .
Regards,
Prateek Divya

You need to do that per index: [https://www.elastic.co/guide/en/elasticsearch/reference/5.2/indices-update-settings.html](https://www.elastic.co/guide/en/elasticsearch/reference/5.2/indices-update-settings.html)
```auto
curl -XPUT 'localhost:9200/my_index/_settings' -d '{
"index.number_of_replicas" : 0
}'
```

It is also possible to create a top-level template that would apply to all newly-created indices.

I tried the same but getting error as "Could not resolve host : 0"
ELK is on windows machine so if that could impact anywhere.

You can do it like this:
```auto
PUT localhost:9200/_template/number_of_replicas
{
"template": "*",
"settings": {
"number_of_replicas": 0
}
}
```
See the [docs](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-templates.html) for more details.

Thanks David. It worked when tried the same on Kibana console not on explicit CURl command line
