[[versioning-pipelines]]
===== Pipeline versioning

When creating or updating an ingest pipeline,
you can specify an optional `version` parameter.
The version is useful for managing changes to pipeline
and viewing the current pipeline for an ingest node.

The following request sets a version number of `123`
for `my-pipeline-id`.

[source,console]
--------------------------------------------------
PUT /_ingest/pipeline/my-pipeline-id
{
  "description" : "describe pipeline",
  "version" : 123,
  "processors" : [
    {
      "set" : {
        "field": "foo",
        "value": "bar"
      }
    }
  ]
}
--------------------------------------------------

To unset the version number,
replace the pipeline without specifying a `version` parameter.

[source,console]
--------------------------------------------------
PUT /_ingest/pipeline/my-pipeline-id
{
  "description" : "describe pipeline",
  "processors" : [
    {
      "set" : {
        "field": "foo",
        "value": "bar"
      }
    }
  ]
