GKE 上的 Knative 不适用于某些图像，显示修订缺失错误

Question

我在GKE集群上运行Knative。Knative 网站上提供的示例图像可以工作，但是当我切换到其他一些图像时，它停止工作。3 个容器中只有 2 个容器工作，路由的就绪状态保持"未知"，原因显示为"修订缺失"。

我尝试了多张图像，k8s.gcr.io/hpa-example 就是其中之一。

编辑：群集具有类型为 n1-standard-4 的双节点配置(4 个 vCPU，15 GB 内存(。我使用带有最新版本 kubernetes 的 GCP 控制台创建了这个集群，并选中了启用 Istio 复选框。我使用以下命令来安装 Knative：

kubectl apply --selector knative.dev/crd-install=true 
-f https://github.com/knative/serving/releases/download/v0.8.0/serving.yaml 
-f https://github.com/knative/eventing/releases/download/v0.8.0/release.yaml 
-f https://github.com/knative/serving/releases/download/v0.8.0/monitoring.yaml
kubectl apply 
-f https://github.com/knative/serving/releases/download/v0.8.0/serving.yaml 
-f https://github.com/knative/eventing/releases/download/v0.8.0/release.yaml 
-f https://github.com/knative/serving/releases/download/v0.8.0/monitoring.yaml

谢谢

好的，我发现了问题。我尝试发布自定义图像。一切都有效，直到我将端口(内部图像(更改为 80。此映像不仅可以用作Knative服务，而且在云运行服务上也不起作用。 底线是，要么从环境变量中提取端口号，要么将其硬编码到 80 以外的任何其他端口。

感谢您的精度。

当你安装Knative时，你应该看到这种错误

您没有安装 Istio。这样做，重新启动knative安装(有和没有CRD(来解决以前的错误并享受!!
