4.2. 使用 YAML 安装 Knative Serving

流程

1. 创建名为 serving.yaml 的文件并将以下示例 YAML 复制到其中：

   apiVersion: operator.knative.dev/v1beta1
   kind: KnativeServing
   metadata:
       name: knative-serving
       namespace: knative-serving

2. 应用 service.yaml 文件：

   $ oc apply -f serving.yaml

验证

1. 使用以下命令校验安装是否完成：

   $ oc get knativeserving.operator.knative.dev/knative-serving -n knative-serving --template='{{range .status.conditions}}{{printf "%s=%s\n" .type .status}}{{end}}'

   输出示例

   DependenciesInstalled=True
   DeploymentsAvailable=True
   InstallSucceeded=True
   Ready=True

   注意

   创建 Knative Serving 资源可能需要几秒钟时间。

   如果条件状态为 Unknown 或 False，请等待几分钟，然后在确认已创建资源后再重新检查。

2. 检查是否已创建 Knative Serving 资源：

   $ oc get pods -n knative-serving

   输出示例

3. 检查所需的网络组件是否已安装到自动创建的 knative-serving-ingress 命名空间：

   $ oc get pods -n knative-serving-ingress

   输出示例
