--token-cache-max-duration | duration | The maximum duration for which a token would be considered unexpired. This is capped at 1h. (default 1h) |
--watch-all-namespaces | boolean | Watch for custom resources in all namespaces, if set to false it will only watch the runtime namespace. (default true) |
--watch-label-selector | string | Watch for resources with matching labels e.g. ‘sharding.fluxcd.io/key=shard1’. |

Feature Gates
| Name | Default Value | Description |
|---|---|---|
CacheSecretsAndConfigMaps | false | Configures the caching of Secrets and ConfigMaps by the controller-runtime client. When enabled, it will cache both object types, resulting in increased memory usage and cluster-wide RBAC permissions (list and watch). |
ObjectLevelWorkloadIdentity | false | Enables the use of object-level workload identity for the controller. |
OptimizedGitClones | true | Optimises Git resource usage by only cloning repositories when the HEAD commit changed since last reconciliation. |
