Aliases permanently to specified indexes

Elastic Stack Elasticsearch

HI Guys ,

I have few indexes patterns that i want to create alias for "wakeupsms" by default.
i already did POST _aliases and it work but didn't effect for new indices .
i tried to put template by the following command but i think i miss something because nothing happend:

PUT _template/wakeupsms
{

"order" : 0,
"index_patterns" : [
  "prod-env-jobs-*",
  "pre_prod-xxx-listener-*"
],
"settings" : {
  "index" : {
    "lifecycle" : {
      "name" : "index-policy"
    },
    "number_of_shards" : "5",
    "number_of_replicas" : "0"
  }
},
"mappings" : { },
"aliases" : {
    "alias1" : {},
  
    "{index}-prod-wakeupsms" : {} 
}

}

what is the solution?
Thanks,

Hey,

take this example. The first part of the alias is actually the alias name, so no need to specify {index} in there

PUT _template/foo-template
{
    "index_patterns" : ["foo-*"],
    "aliases" : {
        "my-alias" : {} 
    }
}

PUT foo-1/_doc/1
{
  "key" : "1"
}

PUT foo-2/_doc/2
{
  "key" : "2"
}

PUT foo-3/_doc/3
{
  "key" : "3"
}

GET my-alias/_search

Hope I understood your request correctly.

Hey! thanks for quick respond
should I rebuild index after put the changes?

5

this is only about creating the index template that only applies on new index creation.

What makes you think you need to rebuild? The short answer is 'no' but I am curious about the reasoning here.

6

because the template is for specified indexes that already in the system and new indexes that will be create everyday

7

the template is only applied when a new index is created, never on existing indices.

See the note right at the top at https://www.elastic.co/guide/en/elasticsearch/reference/7.2/indices-templates.html
