Rotate Authentication of Elasticsearch

This guide will give an overview on how KubeDB Ops-manager operator Rotate Authentication configuration.

Before You Begin

• You should be familiar with the following KubeDB concepts:
  • Elasticsearch
  • ElasticsearchOpsRequest

How Rotate Elasticsearch Authentication Configuration Process Works

The authentication rotation process for Elasticsearch using KubeDB involves the following steps:

1. A user first creates a Elasticsearch Custom Resource Object (CRO).

2. The KubeDB Provisioner operator continuously watches for Elasticsearch CROs.

3. When the operator detects a Elasticsearch CR, it provisions the required PetSets, along with related resources such as secrets, services, and other dependencies.

4. To initiate authentication rotation, the user creates a ElasticsearchOpsRequest CR with the desired configuration.

5. The KubeDB Ops-manager operator watches for ElasticsearchOpsRequest CRs.

6. Upon detecting a ElasticsearchOpsRequest, the operator pauses the referenced Elasticsearch object, ensuring that the Provisioner operator does not perform any operations during the authentication rotation process.

7. The Ops-manager operator then updates the necessary configuration (such as credentials) based on the provided ElasticsearchOpsRequest specification.

8. After applying the updated configuration, the operator restarts all Elasticsearch Pods so they come up with the new authentication environment variables and settings.

9. Once the authentication rotation is completed successfully, the operator resumes the Elasticsearch object, allowing the Provisioner operator to continue its usual operations.

In the next section, we will walk you through a step-by-step guide to rotating Elasticsearch authentication using the ElasticsearchOpsRequest CRD.
