=== Remove Policy On Index API
++++
<titleabbrev>Remove Policy From Index</titleabbrev>
++++

Unassigns a policy from a specified index pattern

==== Request

`DELETE <index>/_ilm`

==== Description

This action removes a policy from managing an index. It is effectively the same as setting an index's
`index.lifecycle.name` setting to null.

==== Path Parameters

`index` (required)::
  (string) Identifier for the index.

==== Request Parameters

`timeout`::
  (time units) Specifies the period of time to wait for the completion of the 
  operation. When this period of time elapses, the API fails and returns
  an error. The default value is `30s`. For more information about time units, 
  see <<time-units>>.

`master_timeout`::
  (time units) Specifies the period of time to wait for the connection with master.
  When this period of time elapses, the API fails and returns an error.
  The default value is `30s`. For more information about time units, see <<time-units>>.


==== Examples

The following example removes a policy `my_policy` from an index `my_index`.
