### Description{% #description %}

When `kube-apiserver` is used, the `--enable-admission-plugins` flag should include `EventRateLimit`. The admission control configuration file must also contain the corresponding `EventRateLimit` configuration. This rule checks the `containers` and `initContainers` command lines for `kube-apiserver` and reports a MissingAttribute if `EventRateLimit` is absent.
