### Description{% #description %}

For containers running `kube-controller-manager`, the `--terminated-pod-gc-threshold` flag must be set to a value between `0` and `12501`. The rule checks the `command` fields in both `initContainers` and `containers` and reports when the flag is missing or set to an incorrect value.
