3.2.3. 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/v1alpha1
    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 UnknownFalse,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
