Interaction with Elasticsearch Cluster API

Our containers for ElasticSearch and Kibana are up and running, so we will be doing the following things:

• Health check ElasticSearch.
• Create an Index.
• Perform insertion, retrieval and deletion.

Before we start

Let's load up the Kibana Console UI in our browser.

• Kibana is running locally on our machine at the port 5601, click the url http://0.0.0.0:5601/app/kibana#/ to open Kibana in our browser
• Click on the Hamburger Menu > Dev Tools to go to the Kibana Console, where we can write our queries to perform operations.

Health Check

Cluster Health API returns a simple status of the cluster.

Kibana Console

GET /_cluster/health

Create An Index

We are going to create a simple index for customers which will store the name of the customer.

Kibana Console

PUT /customer?pretty
{
    "settings" : {
        "number_of_shards" : 2,
        "number_of_replicas" : 0
    },
    "mappings" : {
        "properties" : {
            "name" : { "type" : "text" }
        }
    }
}

Index A Document

Now, let's add a record to the above created index.

Kibana Console

PUT customer/_doc/1
{
  "name": "Mathew Stuart"
}

Get the document from the Index

To get the record from the index,

Kibana Console

GET customer/_doc/1

Delete A document

Finally, let's try to delete the entry that we added previously.

Kibana Console

DELETE customer/_doc/1
