When an Elasticsearch cluster is created, a default user password is generated and stored in a Kubernetes secret. You will need the full credentials to request the Elasticsearch endpoint.

Let's perform the following steps to request Elasticsearch access:

1. Get the password that was generated for the default elastic user:

$ PASSWORD=$(kubectl get secret elasticsearch-es-elastic-user 
-n logging -o=jsonpath='{.data.elastic}' | base64 --decode)

2. Request the Elasticsearch endpoint address:

$ curl -u "elastic:$PASSWORD" -k "https://elasticsearch-es-http:9200"
{
  "name" : "elasticsearch-es-default-2",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "E_ATzAz8Th6oMvd4D_QocA",
  "version" : {...},
  "tagline" : "You Know, for Search"
}

If you are accessing the Kubernetes cluster remotely, you can create a port-forwarding service and use localhost, similar to what can be seen in the following code:

$ kubectl port-forward service/quickstart-es-http 9200
$ curl -u "elastic:$PASSWORD" -k "https://localhost:9200"

Now, we have access to our three-node small Elasticsearch cluster that we deployed on Kubernetes. Next, we need to deploy Kibana to complete the stack.
