Kubernetes儀表不能正常工作

我試圖實現kubernetes儀表板，但所有它在CrashLoopBackoff狀態，並不要緊，我多少次部署有同樣的信念Kubernetes儀表不能正常工作

host-xxx:~ # kubectl get pods --all-namespaces

我有YAML時間從「kubectl創建-f https://rawgit.com/kubernetes/dashboard/master/src/deploy/kubernetes-dashboard-head.yaml」

我n要知道爲什麼我有這樣的錯誤消息，在僕從看起來像拉，我可以與搬運工人把它..

你們有這方面的理論嗎？

圖像成功扳回一和容器未能在POD開始，在這個舞臺上，你可以檢查出來的問題，檢驗容器的日誌：

kubectl logs --namespace=kube-system kubernetes-dashboard-1975554030-80rxv

的kubelet發出警告：

kubelet沒有配置ClusterDNS IP，並且無法使用「ClusterFirst」策略創建Pod。回落到DNSDefault策略。

也許問題與DNS有關，我有一個自定義安裝，儀表板容器只在DNS活動時啓動，驗證日誌以瞭解它爲什麼失敗。

就像早期的回答說，

你可以使用命令kubectl logs --namespace=kube-system kubernetes-dashboard-1975554030-80rxv查看發生了什麼錯誤的詳細信息。

錯誤kubelet does not have ClusterDNS IP configured and cannot create Pod using "ClusterFirst" policy. Falling back to DNSDefault policy.

也許你沒有啓用kubedns分量的是，這可能會導致這個問題。

如果您仍在使用https://rawgit.com/kubernetes/dashboard/master/src/deploy/kubernetes-dashboard-head.yaml創建您的kubernetes儀表板，則可以運行命令kubectl edit pod kubernetes-dashboard-1975554030-80rxv -n kube-system手動將DNS策略更改爲默認值。密鑰應該是spec.template.spec.dnsPolicy到Default然後重新創建此Pod以查看它是否可行。

發現順便說一句，你還可以使用官方的儀表板創建https://github.com/kubernetes/dashboard#getting-started
