Barman Cloud CNPG-I backup plugin
fe445b154f
When an ObjectStore's credentials change (e.g., secret rename), the RBAC Role granting the Cluster's ServiceAccount access to those secrets was not updated because nothing triggered a Cluster reconciliation. Implement the ObjectStore controller's Reconcile to detect referencing Clusters and update their Roles directly. Extract ensureRole into a shared rbac.EnsureRole function used by both the Pre hook and the ObjectStore controller. Handle concurrent modifications between the Pre hook and ObjectStore controller gracefully: AlreadyExists on Create and Conflict on Patch are retried once to avoid propagating transient errors as gRPC failures to CNPG. Replace the custom setOwnerReference helper (ownership.go) with controllerutil.SetControllerReference for both Role and RoleBinding. The old helper read the GVK from the object's metadata and replaced all owner references unconditionally. The new function reads the GVK from the scheme and appends to existing owner references, refusing to overwrite if another controller already owns the object. Both produce identical results for our use case since the Role is always freshly built. The GVK is now resolved from the scheme configured via CUSTOM_CNPG_GROUP/CUSTOM_CNPG_VERSION, which must match the actual CNPG API group (same requirement as the instance sidecar). Add dynamic CNPG scheme registration (internal/scheme) to the operator, instance, and restore managers, replacing hardcoded cnpgv1.AddToScheme calls. Add RBAC permission for the plugin to list/watch Clusters. Signed-off-by: Armando Ruocco <armando.ruocco@enterprisedb.com> |
