Delete an ingest pipeline

To clean up our Elasticsearch cluster for obsolete or unwanted pipelines, we need to call the delete pipeline API with the ID of the pipeline.

Getting ready

You need an up-and-running Elasticsearch installation, as we described in the Downloading and installing Elasticsearch recipe in Chapter 2, Downloading and Setup.

To execute curl via the command line, you need to install curl for your operative system.

How to do it...

To delete an ingestion pipeline in Elasticsearch, we will perform the following steps:

1. We can delete the ingest pipeline via a DELETE call:

           curl -XDELETE 'http://127.0.0.1:9200/_ingest/pipeline/add-user-
           john'
   

2. The result returned by Elasticsearch, if everything is okay, should be:

           {"acknowledged":true}
   

How it works...

The delete pipeline API removes the named pipeline from Elasticsearch.

As the pipelines are kept in memory in every node due to their cluster level storage and the pipelines are always up and running in the ingest node...
