Taints allow a [[node]] to repel a set of pods, in opposite to [[Node Affinity]]

A taint consists of a key, value, and effect. As an argument here, it is expressed as <code>[[key=value:effect]]</code>. The effect must be <code>[[NoSchedule]], [[PreferNoSchedule]] or [[NoExecute]].</code>

* <code>[[kubectl taint]]</code>
