How to Create a User in Elasticsearch

This guide will walk you through the process of creating a user and provide best practices for user management.

User creation is necessary when setting up initial access control for your Elasticsearch cluster, or when implementing role-based access control (RBAC) for different user types

Steps to Create a User in Elasticsearch

  1. Ensure that security features are enabled in your Elasticsearch configuration.

  2. Use the Elasticsearch Security API or Kibana UI to create the user:

    a. Using the Security API:

    POST /_security/user/<username>
    {
      "password" : "strongpassword",
      "roles" : [ "role1", "role2" ],
      "full_name" : "Full Name",
      "email" : "user@example.com",
      "metadata" : {
        "team" : "engineering"
      }
    }
    

    b. Using Kibana UI:

    • Navigate to Stack Management > Security > Users
    • Click "Create user"
    • Fill in the required fields and assign roles
    • Click "Create user" to save
  3. Verify the user creation by attempting to authenticate with the new credentials.

  4. Assign appropriate roles to the user based on their required access levels.

Best Practices for User Creation and Management

  1. Use strong, unique passwords for each user.
  2. Implement the principle of least privilege by assigning only necessary roles.
  3. Regularly audit user accounts and remove or disable inactive ones.
  4. Use built-in roles where possible, and create custom roles for specific needs.
  5. Consider using LDAP or Active Directory integration for centralized user management.
  6. Enable multi-factor authentication for additional security.
  7. Rotate passwords periodically, especially for administrative accounts.

Frequently Asked Questions

Q: Can I create users without enabling security features in Elasticsearch?
A: No, security features must be enabled to use Elasticsearch's built-in user management system. If security is disabled, you'll need to rely on network-level security measures.

Q: How many users can I create in Elasticsearch?
A: There is no hard limit on the number of users you can create in Elasticsearch. However, for performance reasons, it's recommended to keep the number of users manageable and use role-based access control for scalability.

Q: Can I change a user's password after creation?
A: Yes, you can change a user's password using the Security API or Kibana UI. Users can also change their own passwords if they have the appropriate permissions.

Q: What happens if I delete a user that owns index data?
A: Deleting a user does not affect the data they own or have created. Access to that data will be governed by the permissions of other users or roles that have access to the relevant indices.

Q: Can I create users programmatically in Elasticsearch?
A: Yes, you can create users programmatically using the Elasticsearch Security API. This allows for automation of user management tasks and integration with external systems.
