+<!--
+In Kubernetes, _affinity_ is a set of rules that give hints to the scheduler about where to place pods.
+-->
+在 Kubernetes 中，_亲和性（affinity）_是一组规则，它们为调度程序提供在何处放置 Pods 提示信息。
+<!--more-->
+<!--
+There are two kinds of affinity:
+-->
+亲和性有两种：
+<!--
+* [node affinity](/docs/concepts/scheduling-eviction/assign-pod-node/#node-affinity)
+* [pod-to-pod affinity](/docs/concepts/scheduling-eviction/assign-pod-node/#inter-pod-affinity-and-anti-affinity)

+* [节点亲和性](/zh/docs/concepts/scheduling-eviction/assign-pod-node/#node-affinity)
+* [Pod 间亲和性](/zh/docs/concepts/scheduling-eviction/assign-pod-node/#inter-pod-affinity-and-anti-affinity)
+
+<!--
+The rules are defined using the Kubernetes {{< glossary_tooltip term_id="label" text="labels">}},
+and {{< glossary_tooltip term_id="selector" text="selectors">}} specified in {{< glossary_tooltip term_id="pod" text="pods" >}}, 
+and they can be either required or preferred, depending on how strictly you want the scheduler to enforce them.

+这些规则是使用 Kubernetes {{< glossary_tooltip term_id="label" text="标签">}}（label）
+和 {{< glossary_tooltip term_id="pod" text="pods" >}} 中指定的
+{{< glossary_tooltip term_id="selector" text="选择算符">}}定义的，
+这些规则可以是必需的或首选的，这取决于你希望调度程序执行它们的严格程度。
