      kind: PoisonPillRemediationTemplate
      metadata:
        namespace: openshift-machine-api
        name: poisonpillremediationtemplate-sample
      spec:
        template:
          spec: {}

   2. 要创建 PoisonPillRemediationTemplate CR，请运行以下命令：

      $ oc create -f <ppr-name>.yaml

2. 创建或更新 MachineHealthCheck CR 以指向 PoisonPillRemediationTemplate CR：

   1. 定义或更新 MachineHealthCheck CR：

      apiVersion: machine.openshift.io/v1beta1
      kind: MachineHealthCheck
      metadata:
        name: machine-health-check
        namespace: openshift-machine-api
      spec:
        selector:
          matchLabels:
            machine.openshift.io/cluster-api-machine-role: "worker"
            machine.openshift.io/cluster-api-machine-type: "worker"
        unhealthyConditions:
        - type:    "Ready"
          timeout: "300s"
          status: "False"
        - type:    "Ready"
          timeout: "300s"
          status: "Unknown"
        maxUnhealthy: "40%"
        nodeStartupTimeout: "10m"
        remediationTemplate: 1
          kind: PoisonPillRemediationTemplate
          apiVersion: poison-pill.medik8s.io/v1alpha1
          name: <poison-pill-remediation-template-sample>

      1

      指定补救模板的详细信息。

   2. 要创建 MachineHealthCheck CR，请运行以下命令：
