--log-level | string | Log verbosity level. Can be one of ’trace’, ‘debug’, ‘info’, ’error’. (default “info”) |
--max-retry-delay | duration | The maximum amount of time for which an object being reconciled will have to wait before a retry. (default 15m0s) |
--metrics-addr | string | The address the metric endpoint binds to. (default “:8080”) |

--watch-label-selector | string | Watch for resources with matching labels e.g. ‘sharding.fluxcd.io/shard=shard1’. |
--feature-gates | mapStringBool | A comma separated list of key=value pairs defining the state of experimental features. |
--interval-jitter-percentage | uint8 | Percentage of jitter to apply to interval durations. A value of 10 will apply a jitter of +/-10% to the interval duration. It cannot be negative, and must be less than 100. (default 5) |

|---|---|---|
OptimizedGitClones | true | Optimises Git resource usage by only cloning repositories when the HEAD commit changed since last reconciliation. |
