12.4. 使用 CLI 安装 Topology Aware Lifecycle Manager

流程

1. 创建一个 Subscription CR：

   1. 定义 Subscription CR 并保存 YAML 文件，如 talm-subscription.yaml ：

      apiVersion: operators.coreos.com/v1alpha1
      kind: Subscription
      metadata:
        name: openshift-topology-aware-lifecycle-manager-subscription
        namespace: openshift-operators
      spec:
        channel: "stable"
        name: topology-aware-lifecycle-manager
        source: redhat-operators
        sourceNamespace: openshift-marketplace

   2. 运行以下命令来创建 Subscription CR：

      $ oc create -f talm-subscription.yaml

验证

1. 检查 CSV 资源来验证安装是否成功：

   $ oc get csv -n openshift-operators

   输出示例

   NAME                                                   DISPLAY                            VERSION               REPLACES                           PHASE
   topology-aware-lifecycle-manager.4.16.x   Topology Aware Lifecycle Manager   4.16.x                                      Succeeded

2. 验证 TALM 是否正在运行：

   $ oc get deploy -n openshift-operators

   输出示例

   NAMESPACE                                          NAME                                             READY   UP-TO-DATE   AVAILABLE   AGE
   openshift-operators                                cluster-group-upgrades-controller-manager        1/1     1            1           14s
