A key-value pair and an effect to prevent the scheduling of pods on nodes or node groups.

Taints and {{< glossary_tooltip text="Tolerations" term_id="toleration" >}} work together to ensure that pods are not scheduled onto inappropriate nodes. One or more taints are applied to a {{< glossary_tooltip text="node" term_id="node" >}}; this marks that the {{< glossary_tooltip text="node" term_id="node" >}} should not accept any pods that do not tolerate the taints.
