From d05559a07ff4a10f747d5c81b595846283c1ced3 Mon Sep 17 00:00:00 2001 From: Armando Ruocco Date: Thu, 26 Mar 2026 13:56:03 +0100 Subject: [PATCH] fix(rbac): reconcile Role when ObjectStore spec changes 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. The shared EnsureRole accepts optional beforeCreate callbacks so the Pre hook can set owner references on Role creation, while the ObjectStore controller path skips ownership (it only updates existing Roles). Handle deleted ObjectStores gracefully by skipping NotFound errors during Role reconciliation, and filter status-only changes with GenerationChangedPredicate. Add RBAC permission for the plugin to list/watch Clusters so the ObjectStore controller can find affected Clusters. Regenerate config/rbac/role.yaml.
