Is it possible for Elasticsearch to put alias name for index patterns for future indexes?

I know that I can put alias names for existing indexes via

POST /_aliases
{
    "actions" : [
        { "add" : { "index" : "my-index-000001", "alias" : "alias1" } }
    ]
}

or (seems to be equal in outcome)

PUT /my-index-000001/_alias/alias1

but is it also possible to create an alias via patterns, so that new created indexes already come with an alias?

so when i do this:

POST /_aliases
    {
        "actions" : [
            { "add" : { "index" : "my-index-*", "alias" : "alias1" } }
        ]
    }

All indexes created in the future which match pattern my-index-* will automatically come with alias alias1?

Yes it is possible. you can see this link. You need to define an index template.

PUT _template/template_1
{
    "index_patterns" : ["te*"],
    "settings" : {
        "number_of_shards" : 1
    },
    "aliases" : {
        "alias1" : {}
        
    }
}

Yes, you can do it like this using an index template:

PUT _index_template/my_template
{
  "index_patterns": ["my-index-*"],
  "template": {
    "settings": {
      "number_of_shards": 1
    },
    "aliases": {
      "alias1": { }
    },
    "mappings": {
      "properties": {
        ...
      }
    }
  }
}

Note that if you're on a version before 7.8, the syntax is a little bit different:

PUT _template/my_template
{
  "index_patterns": ["my-index-*"],
  "settings": {
    "number_of_shards": 1
  },
  "aliases": {
    "alias1": { }
  },
  "mappings": {
    "properties": {
      ...
    }
  }
}
