  • MariaDBOpsRequest

How Rotate MariaDB Authentication Configuration Process Works

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

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

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

3. When the operator detects a MariaDB 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 MariaDBOpsRequest CR with the desired configuration.

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

6. Upon detecting a MariaDBOpsRequest, the operator pauses the referenced MariaDB 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 MariaDBOpsRequest specification.

8. After applying the updated configuration, the operator restarts all MariaDB 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 MariaDB 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 MariaDB authentication using the MariaDBOpsRequest CRD.
