Rotate Authentication of Solr

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

• You should be familiar with the following KubeDB concepts:
  • Solr
  • SolrOpsRequest

How Rotate Solr Authentication Configuration Process Works

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

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

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

3. When the operator detects a Solr 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 SolrOpsRequest CR with the desired configuration.

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

6. Upon detecting a SolrOpsRequest, the operator pauses the referenced Solr 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 SolrOpsRequest specification.

8. After applying the updated configuration, the operator restarts all Solr 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 Solr 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 Solr authentication using the SolrOpsRequest CRD.
