无法获取kubernetes仪表板

Question

I've installad a new cluster (version 1.13.5 of kubectl kubelet kubeadm), then I've installed flannel and add a worker node. Now I'm trying to add kubernetes dashboard to my cluster but after i run

$ kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml

I've this situation

kubernetes-dashboard-****   0/1     CrashLoopBackOff   1          8s

Then if I get the log i can see this

 Error while initializing connection to Kubernetes apiserver...

Where I'm wrong?

Answer 1

It seems that the problem was on the worker, when I put the dashboard on master the pod starts. Maybe the kube dashboard has to be installed on the master or there is something wrong with flannel and the master-node communication.

Answer 2

检查api-server pod是否正在运行，以及KubeDNS是否正常运行。
