5.7.3. 使用 CLI 安装 Node Health Check Operator

流程

1. 为 Node Health Check Operator 创建 Namespace 自定义资源 (CR)：

   1. 定义 Namespace CR 并保存 YAML 文件，如 node-health-check-namespace.yaml ：

      apiVersion: v1
      kind: Namespace
      metadata:
        name: openshift-operators

      Copy to Clipboard

   2. 要创建 Namespace CR，请运行以下命令：

      $ oc create -f node-health-check-namespace.yaml

      Copy to Clipboard

2. 创建 OperatorGroup CR：

   1. 定义 OperatorGroup CR 并保存 YAML 文件，如 node-health-check-operator-group.yaml ：

      apiVersion: operators.coreos.com/v1
      kind: OperatorGroup
      metadata:
        name: node-health-check-operator
        namespace: openshift-operators
      spec:
        targetNamespaces:
        - openshift-operators

      Copy to Clipboard

   2. 要创建 OperatorGroup CR，请运行以下命令：

      $ oc create -f node-health-check-operator-group.yaml

      Copy to Clipboard

3. 创建一个 Subscription CR：

   1. 定义 Subscription CR 并保存 YAML 文件，如 node-health-check-subscription.yaml ：

      apiVersion: operators.coreos.com/v1alpha1
      kind: Subscription
      metadata:
          name: node-health-check-operator
          namespace: openshift-operators
      spec:
          channel: alpha
          name: node-healthcheck-operator
          source: redhat-operators
          sourceNamespace: openshift-marketplace
          package: node-health-check-operator

      Copy to Clipboard

   2. 要创建 Subscription CR，请运行以下命令：

      $ oc create -f node-health-check-subscription.yaml

      Copy to Clipboard

验证

1. 检查 CSV 资源来验证安装是否成功：

   $ oc get csv -n openshift-operators

   Copy to Clipboard

   输出示例

   NAME                               DISPLAY                      VERSION   REPLACES   PHASE
   node-health-check-operator.v0.1.1  Node Health Check Operator   0.1.1                Succeeded

   Copy to Clipboard

2. 验证 Node Health Check Operator 是否正在运行：

   $ oc get deploy -n openshift-operators

   Copy to Clipboard

   输出示例

   NAME                                           READY   UP-TO-DATE   AVAILABLE   AGE
   node-health-check-operator-controller-manager  1/1     1            1           10d
