Get an ingest pipeline

After having stored your pipeline, it is common to retrieve its content, for checking its definition. This action can be done via the get pipeline API.

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

1. We can retrieve the ingest pipeline via a GET call:

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

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

           {
             "add-user-john" : {
               "description" : "Add user john field",
               "processors" : [
                 {
                   "set" : {
                     "field" : "user",
                     "value" : "john"
              ...
