Elasticsearch only has one node I created template in error e.g. 1 shard (Primary) and 1 replica so I have updated the template for no replica.
PUT friday-000012/\_settings
{"number\_of\_replicas": 0}
I checked the template and all look fine.
{
"friday\_template" : {
"order" : 0,
"index\_patterns" : [
"friday\*"
],
"settings" : {
"index" : {
"lifecycle" : {
"name" : "friday\_policy",
"rollover\_alias" : "friday-alias"
},
"number\_of\_shards" : "1",
"number\_of\_replicas" : "0"
}
},
"mappings" : { },
"aliases" : { }
}
}
But after 1 day rollover I see 1 primary and 1 replica for some reason.

Please advise.

Templates are not retrospective, so if you want to remove them from older indices you need to update them specifically.

I did update the older indices as example below command for any yellow status, this updated from yellow to green but next roll over (next day) I see yellow again which is 1 shard and 1 replica but the template is correct.
PUT friday-000012/\_settings
{"number\_of\_replicas": 0}
Please advise.
