I was reading this great article ...

`https://www.elastic.co/blog/implementing-hot-warm-cold-in-elasticsearch-with-index-lifecycle-management`

But in this article there is a line as following

**For policies that include the rollover action, you must also bootstrap the index with a write alias after creating the index template**

```auto
PUT test-000001 
{
  "aliases": {
    "test-alias":{
      "is_write_index": true 
    }
  }
} 

```

what i am wondering or confuse about is that i am understanding that we have to make the Index Life cycle management policy only once to automate this process of rollover.  
but as you can see in the above snipped that we are using a specific index/index\_name as in this case **test-000001** so we have to manually do this every time an index is going to be role over or we should use a index template name instead which we use while associating ILM (index lifecycle management) policy with index template such as \*\*_test-_ \*\*\*. I'm just confuse and new to elastic.

```auto
PUT _template/my_template
{
  "index_patterns": ["test-*"], 
  "settings": {
    "index.lifecycle.name": "my_policy", 
    "index.lifecycle.rollover_alias": "test-alias" 
  }
}

```
