If the Elasticsearch security features are enabled, you must have the manage_ilm cluster privilege to use this API. You must also have the manage index privilege on all indices being managed by policy. ILM performs operations as the user who last updated the policy. ILM only has the roles assigned to the user at the time of the last policy update.

Only the latest version of the policy is stored, you cannot revert to previous versions.

Examples

The following example creates a new policy named my_policy. In addition, you can use the _meta parameter to add arbitrary metadata to the policy, the _meta parameter is optional and not automatically generated or used by Elasticsearch. To unset _meta, replace the policy without specifying one. To check the _meta, you can use the Get lifecycle policy API.

PUT _ilm/policy/my_policy
{
  "policy": {
    "_meta": {
      "description": "used for nginx log",
      "project": {
        "name": "myProject",
        "department": "myDepartment"
      }
