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 node. A node should only schedule a Pod with the matching tolerations for the configured taints.

污点和{{< glossary_tooltip text="容忍度" term_id="toleration" >}}一起工作，
|
||
以确保不会将 Pod 调度到不适合的节点上。
|
||
同一{{< glossary_tooltip text="节点" term_id="node" >}}上可标记一个或多个污点。
|
||
节点应该仅调度那些带着能与污点相匹配容忍度的 Pod。
