将事件源发布到您的集群

1. 启动一个 minikube 集群

   minikube start
   

2. 设置 ko 以使用 minikube docker 实例和本地注册表

   eval $(minikube docker-env)
   export KO_DOCKER_REPO=ko.local
   

3. 应用 CRD 和配置 YAML

   ko apply -f config
   

4. 一旦 sample-source-controller-manager 在 knative-samples 命名空间中运行，您就可以应用 example.yaml 以每 10s 将我们的 sample-source 直接连接到 ksvc。

   apiVersion: serving.knative.dev/v1
   kind: Service
   metadata:
     name: event-display
     namespace: knative-samples
   spec:
     template:
       spec:
         containers:
           - image: gcr.io/knative-releases/knative.dev/eventing/cmd/event_display
   ---
   apiVersion: samples.knative.dev/v1alpha1
   kind: SampleSource
   metadata:
     name: sample-source
     namespace: knative-samples
   spec:
     interval: "10s"
     sink:
       ref:
         apiVersion: serving.knative.dev/v1
         kind: Service
         name: event-display
   

   ko apply -f example.yaml
   

5. 调和后，您可以确认 ksvc 每 10s 输出有效的 cloudevents，以与我们指定的间隔保持一致。

   % kubectl -n knative-samples logs -l serving.knative.dev/service=event-display -c user-container -f
