Tolerations and {{< glossary_tooltip text="taints" term_id="taint" >}} work together to ensure that pods are not scheduled onto inappropriate nodes. One or more tolerations are applied to a {{< glossary_tooltip text="pod" term_id="pod" >}}. A toleration indicates that the {{< glossary_tooltip text="pod" term_id="pod" >}} is allowed (but not required) to be scheduled on nodes or node groups with matching {{< glossary_tooltip text="taints" term_id="taint" >}}.

容忍度和{{< glossary_tooltip text="污点" term_id="taint" >}}共同作用可以
|
||
确保不会将 Pod 调度在不适合的节点上。
|
||
在同一 {{< glossary_tooltip text="Pod" term_id="pod" >}} 上可以设置一个
|
||
或者多个容忍度。
|
||
容忍度表示在包含对应{{< glossary_tooltip text="污点" term_id="taint" >}}
|
||
的节点或节点组上调度 {{< glossary_tooltip text="Pod" term_id="pod" >}}
|
||
是允许的（但不必要）。
