我正在尝试将 Knative 与大使一起使用。按照以下步骤安装 Knative，
安装 Knative
kubectl apply --filename https://github.com/knative/serving/releases/download/v0.13.0/serving-crds.yaml
kubectl apply --filename https://github.com/knative/serving/releases/download/v0.13.0/serving-core.yaml
配置大使，
kubectl set env --namespace ambassador deployments/ambassador AMBASSADOR_KNATIVE_SUPPORT=true
配置 Knative 使用 ambassdor 作为入口，
kubectl patch configmap/config-network --namespace knative-serving --type merge --patch '{"data":"ingress.class":"ambassador.ingress.networking.knative.dev"}}'
我已经在“ambassador-ns”命名空间下安装了大使。它工作正常。
部署 hello world 应用程序，
apiVersion: serving.knative.dev/v1 # Current version of Knative
kind: Service
metadata:
name: helloworld-go # The name of the app
namespace: default # The namespace the app will use

containers:

value: "Go Sample v1"
当我检查 ksvc 的状态时，

你能告诉我我做错了什么吗？
