Deleting a Release deletes its CRDs and Namespaces, also when the prune policy protects them

Behavior#

During a sync, the prune does not delete a CustomResourceDefinition or a Namespace unless prune.includeCRDs or prune.includeNamespaces is true. When you delete a Release with deletionPolicy.keepWorkloads: false, convoy deletes all objects in the ReleaseInventory. It does not use the prune protection.

Effect#

• A deleted CRD deletes all custom resources of that type in the cluster, also resources that other Releases or other tools own.
• A deleted Namespace deletes all objects in that namespace.

Workaround#

Before you delete a Release that applied CRDs or Namespaces, set deletionPolicy.keepWorkloads: true. Then delete the other objects yourself.

Fix direction#

Use the prune protection (includeCRDs, includeNamespaces) also when a Release is deleted.
