5 Delete the TimesTen Operator and Node Pool

You can delete the TimesTen Operator by destroying the stack you created for TimesTen Database for OKE. Destroying the stack will remove all the resources that the stack created including the managed node pool and worker nodes created for TimesTen databases.

However, this operation does not remove the user-provided Secret with the Oracle Container Registry credentials, any user-created ConfigMaps and Secrets used to create the TimesTenClassic objects, or the TimesTenClassic objects. It is highly recommended that you, at least, delete any TimesTenClassic objects you created before destroying the stack, see Clean Up or Delete TimesTen Databases in Oracle TimesTen In-Memory Database Kubernetes Operator User's Guide.

If the stack deployed the TimesTen Operator on a worker node outside of the node pool the stack created for TimesTen databases, the destroy stack operation only removes the Pod for the TimesTen Operator and any resources the stack originally added to the OKE cluster configuration to deploy the TimesTen Operator, such as the TimesTenClassic CRD, the role and service account for the TimesTen Operator.

Note:

Deleting the stack and destroying the stack are separate operations and perform different actions:

  • Destroy stack: Removes all resources deployed by the stack, but the stack remains available in Resource Manager and you can recreate all thsese resources by rerunning the apply job.

  • Delete stack: Removes the stack from Resource Manager, but any associated resources persist. If the stack has not been destroyed first, you will need to remove the all resources deployed by the stack by different means.

To ensure that all resources are removed and the stack deleted from Resource Manager, destroy and then delete the stack.
