      Anyone applying toleration(s) in a pod spec can unintentionally tolerate master taints which protect master nodes from receiving application workload when master nodes are configured to repel application workload. An admission plugin needs to be configured to protect master nodes from this scenario. Besides the taint/toleration, users can also set spec.NodeName directly, which this plugin should also consider protecting master nodes against.
