Kube-ui 未启动

Question

我一直在尝试设置 ui，但经过多次尝试后，我还是没能成功。我正在 Raspberry Pi 2 using the Kubernetes on Arm project.

安装 kubernetes

要启动 kube-ui 我运行以下命令：

kubectl create -f addons/kube-ui/kube-ui-rc.yaml --namespace=kube-system
kubectl create -f addons/kube-ui/kube-ui-svc.yaml --namespace=kube-system

它开始 correctyl 但是当我去 http://[master-ip]:8080/ui it redirects to http://[master-ip]/api/v1/proxy/namespaces/kube-system/services/kube-ui/#/dashboard/。接下来json显示：

{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {},
  "status": "Failure",
  "message": "no endpoints available for service \"kube-ui\"",
  "reason": "ServiceUnavailable",
  "code": 503
}

然后我检查了 pod kube-ui 的状态：

kubectl describe pods kube-ui --namespace=kube-system

事件是：

Master-ip = 192.168.1.20

Node-ip = 192.168.1.21

Answer 1

事件流的最后一行显示了问题：

Error: image kubernetesonarm/kube-ui:latest not found

https://hub.docker.com/u/kubernetesonarm/ 显示已为 ARM 编译的容器列表。

另请注意 kubernetes-on-arm 文档说：

kube-ui was removed, because the Kubernetes team shifted focus to dashboard.
