Node1 节点具有标签 zone:us：

$ oc label node node1 zone=us

pod pod-s1 在节点关联性必要规则下具有 zone 和 us 键/值对：

$ cat pod-s1.yaml
apiVersion: v1
kind: Pod
metadata:
  name: pod-s1
spec:
  containers:
    - image: "docker.io/ocpqe/hello-pod"
      name: hello-pod
  affinity:
    nodeAffinity:
      requiredDuringSchedulingIgnoredDuringExecution:
        nodeSelectorTerms:
          - matchExpressions:
            - key: "zone"
              operator: In
              values:
              - us

使用标准命令创建 pod：

$ oc create -f pod-s1.yaml
pod "pod-s1" created

pod pod-s1 可以调度到 Node1 上：

$ oc get pod -o wide
NAME     READY     STATUS       RESTARTS   AGE      IP      NODE
pod-s1   1/1       Running      0          4m       IP1     node1
