  • Druid
  • DruidOpsRequest

How Rotate Druid Authentication Configuration Process Works

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

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

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

3. When the operator detects a Druid 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 DruidOpsRequest CR with the desired configuration.

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

6. Upon detecting a DruidOpsRequest, the operator pauses the referenced Druid 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 DruidOpsRequest specification.

8. After applying the updated configuration, the operator restarts all Druid 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 Druid 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 Druid authentication using the DruidOpsRequest CRD.
