GKE 上的 Knative 无法处理某些图像，显示 RevisionMissing 错误

Question

我是运行 GKE 集群上的 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，它会停止工作。 3 个容器中只有 2 个容器工作，路由的就绪状态保持 'unknown'，原因显示为 'RevisionMissing'。

我尝试了多张图片，k8s.gcr。io/hpa-example 是其中一张。

编辑： 集群有一个 n1-standard-4 类型的双节点配置（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

感谢您的精确。

当您安装 Knative 时，您应该会看到这种错误

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

好的，我找到问题了。我尝试发布自定义图像。一切正常，直到我将端口（内部图像）更改为 80。此图像不仅可以作为 Knative 服务使用，而且，它也不适用于 Cloud 运行服务。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。
