Curl command to set the number of replicas

Elastic Stack Elasticsearch
#1

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 -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

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.

#5

Please suggest how to create a top-level template. I have not done earlier so have no context around same.

#6

You can do it like this:

PUT localhost:9200/_template/number_of_replicas
{
  "template": "*",
  "settings": {
    "number_of_replicas": 0
  }
}

See the docs for more details.
