Hi,

i have to create alias with indexname,month and year.

```
{
  "template": data-*",
  "settings": {
    "number_of_shards": 1
  },
  "aliases": {
    "my_index-%{year}-%{month}": {}
  }
}

```

When the i tried above template it is creating alias with exact string i specified(i.e.my\_index-%{year}-%{month}) rather than printing year and month (i.e data-2017-03) .

FYI - My index is in the format `data-2017-03-25` .

IS it possible to create dynamic alias in index templates?

Thanks

My original answer here hasn't changed. Also, please don't post the same thing multiple times.
