Create pipeline

Use the create pipeline API operation to create or update pipelines in OpenSearch. Note that the pipeline requires you to define at least one processor that specifies how to change the documents.

Path and HTTP method

Replace <pipeline-id> with your pipeline ID:

PUT _ingest/pipeline/<pipeline-id>

Example request

Here is an example in JSON format that creates an ingest pipeline with two set processors and an uppercase processor. The first set processor sets the grad_year to 2023, and the second set processor sets graduated to true. The uppercase processor converts the name field to uppercase.

PUT _ingest/pipeline/my-pipeline
{
  "description": "This pipeline processes student data",
  "processors": [
    {
      "set": {
        "description": "Sets the graduation year to 2023",
        "field": "grad_year",
        "value": 2023
      }
    },
    {
      "set": {
        "description": "Sets graduated to true",
        "field": "graduated",
        "value": true
      }
    },
    {
      "uppercase": {
        "field": "name"
      }
    }
  ]
}

Template snippets

Some processor parameters support Mustache template snippets. To get the value of a field, surround the field name in three curly braces, for example, {{{field-name}}}.

Example: set ingest processor using Mustache template snippet

The following example sets the field {{{role}}} with a value {{{tenure}}}:

PUT _ingest/pipeline/my-pipeline
{
 "processors": [
    {
      "set": {
        "field": "{{{role}}}",
        "value": "{{{tenure}}}"
         }
    }
  ]
}
