* *kubelet_streaming_connection_idle_timeout* - Set the maximum time a streaming connection can be idle before the connection is automatically closed.
* *kubelet_image_gc_high_threshold* - Set the percent of disk usage after which image garbage collection is always run.
The percent is calculated by dividing this field value by 100, so this field must be between 0 and 100, inclusive.
When specified, the value must be greater than imageGCLowThresholdPercent. Default: 85
* *kubelet_image_gc_low_threshold* - Set the percent of disk usage before which image garbage collection is never run.
Lowest disk usage to garbage collect to.
The percent is calculated by dividing this field value by 100, so the field value must be between 0 and 100, inclusive.
When specified, the value must be less than imageGCHighThresholdPercent. Default: 80
* *kubelet_make_iptables_util_chains* - If `true`, causes the kubelet ensures a set of `iptables` rules are present on host.
* *kubelet_systemd_hardening* - If `true`, provides kubelet systemd service with security features for isolation.
