Move to lifecycle step APIedit

Triggers execution of a specific step in the lifecycle policy.

Requestedit

POST _ilm/move/<index>

Prerequisitesedit

  • If the Elasticsearch security features are enabled, you must have the manage_ilm privileges on the indices being managed to use this API. For more information, see Security privileges.

Descriptionedit

This operation can result in the loss of data. Manually moving an index into a specific step executes that step even if it has already been performed. This is a potentially destructive action and this should be considered an expert level API.

Manually moves an index into the specified step and executes that step. You must specify both the current step and the step to be executed in the body of the request.

The request will fail if the current step does not match the step currently being executed for the index. This is to prevent the index from being moved from an unexpected step into the next step.

Path parametersedit

<index>
(Required, string) Identifier for the index.

Query parametersedit

master_timeout
(Optional, time units) Specifies the period of time to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error. Defaults to 30s.
timeout
(Optional, time units) Specifies the period of time to wait for a response. If no response is received before the timeout expires, the request fails and returns an error. Defaults to 30s.

Request bodyedit

current_step

(Required, object)

Properties of current_step
phase
(Required, string) The name of the current phase. Must match the phase as returned by the explain API.
action
(Required, string) The name of the current action. Must match the action as returned by the explain API.
name
(Required, string) The name of the current step. Must match the step as returned by the explain API. If ILM encounters a problem while performing an action, it halts execution of the policy and transitions to the ERROR step. If you are trying to advance a policy after troubleshooting a failure, you specify this ERROR step as the current step. For more information, see ILM error handling.
next_step

(Required, object)

Properties of next_step
phase
(Required, string) The name of the phase that contains the action you want to perform or resume.
action
(Required, string) The name action you want to perform or resume.
name
(Required, string) The name of the step to move to and execute.

Examplesedit

The following example moves my_index from the initial step to the forcemerge step:

POST _ilm/move/my_index
{
  "current_step": { 
    "phase": "new",
    "action": "complete",
    "name": "complete"
  },
  "next_step": { 
    "phase": "warm",
    "action": "forcemerge",
    "name": "forcemerge"
  }
}

The step that the index is expected to be in

The step that you want to execute

If the request succeeds, you receive the following result:

{
  "acknowledged": true
}

The request will fail if the index is not in the new phase as specified by the current_step.
