elasticsearchHow do I create a user in Elasticsearch?

Creating a user in Elasticsearch is a simple process. The following example code will create a user with the username elastic and the password changeme:

PUT /_security/user/elastic
{
  "password" : "changeme",
  "roles" : [ "superuser" ]
}

This will return an output indicating that the user was created successfully:

{
  "created" : true
}

The code consists of a PUT request to the endpoint /_security/user/elastic, followed by a JSON object containing the user's password and roles. The roles in this example are set to superuser, which gives the user full access to the cluster.

You can also specify additional roles, such as admin, monitoring or kibana_user. For more information on roles and user management, see the Elasticsearch documentation.
