To cleanup Trilio for Kubernetes, the custom resources, CRDs and the Operator must be removed from the Kubernetes cluster or namespace. There are two ways users can cleanup T4K - automated (via a Trilio provided plugin) or manually removing all the items.

The automation provides a non-interactive mode to allow unattended uninstall of the solution, and also provides an interactive mode to specifically uninstall different components. For further details, refer to the T4K Cleanup Plugin.
