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，它会停止工作。3 个容器中只有 2 个容器工作，并且路由的就绪状态保持“未知”，原因显示为“RevisionMissing”。

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

编辑：集群有一个配置类型为 n1-standard-4 的两个节点（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 Enable 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

好的，我发现了问题。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。此图像不仅可以用作 Knative 服务，而且它也不适用于 Cloud run 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。

感谢您的精确度。

当您安装 Knative 时，您应该会看到此类错误

你没有安装 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！
