Deleting an ingest pipeline
To clean up our Elasticsearch cluster of obsolete or unwanted pipelines, we need to call the delete pipeline API with the ID of the pipeline.
Getting ready

To execute the commands, any HTTP client can be used, such as curl (https://curl.haxx.se/), Postman (https://www.getpostman.com/), or similar. Use the Kibana console, as it provides code completion and better character escaping for Elasticsearch.

The result that's returned by Elasticsearch, if everything is okay, should be as follows:
{ "acknowledged" : true }
