Kubernetes dashboard keeps pending with message: no endpoints available for service “kubernetes-dashboard”

问题:

Heeey all, I need some help with getting the dashboard to work. My dashboard pod has status "Pending" and if I do a curl call to http://127.0.0.1:8080/api/v1/proxy/namespaces/kube-system/services/kubernetes-dashboard then I get this result:

"no endpoints available for service \"kubernetes-dashboard\""

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

All pods

core@helena-coreos ~ $ ./kubectl get po --namespace=kube-system NAME                                     READY     STATUS    RESTARTS   AGE kube-apiserver-146.185.128.27            1/1       Running   0          5d kube-apiserver-37.139.31.151             1/1       Running   0          7d kube-controller-manager-146.185.128.27   1/1       Running   0          19h kube-controller-manager-37.139.31.151    1/1       Running   0          16h kube-dns-v11-ika0m                       0/4       Pending   0          19h kube-proxy-146.185.128.27                1/1       Running   0          5d kubernetes-dashboard-1775839595-1h0lt    0/1       Pending   0          19h 

Describe pod:

core@helena-coreos ~ $ ./kubectl describe pod kubernetes-dashboard-1775839595-1h0lt --namespace="kube-system" Name:       kubernetes-dashboard-1775839595-1h0lt Namespace:  kube-system Node:       / Labels:     app=kubernetes-dashboard,pod-template-hash=1775839595 Status:     Pending IP:      Controllers:    ReplicaSet/kubernetes-dashboard-1775839595 Containers:   kubernetes-dashboard:     Image:  gcr.io/google_containers/kubernetes-dashboard-amd64:v1.1.0     Port:   9090/TCP     QoS Tier:       cpu:  BestEffort       memory:   BestEffort     Liveness:   http-get http://:9090/ delay=30s timeout=30s period=10s #success=1 #failure=3     Environment Variables: Volumes:   default-token-mn7e9:     Type:   Secret (a volume populated by a Secret)     SecretName: default-token-mn7e9 No events. 

Service configuration:

core@helena-coreos ~ $ ./kubectl get svc kubernetes-dashboard --namespace=kube-system -o yaml apiVersion: v1 kind: Service metadata:   creationTimestamp: 2016-07-10T22:25:03Z   labels:     app: kubernetes-dashboard   name: kubernetes-dashboard   namespace: kube-system   resourceVersion: "58669"   selfLink: /api/v1/namespaces/kube-system/services/kubernetes-dashboard   uid: 25d56060-46ed-11e6-9817-040124359901 spec:   clusterIP: 10.3.0.67   ports:   - nodePort: 32014     port: 80     protocol: TCP     targetPort: 9090   selector:     app: kubernetes-dashboard   sessionAffinity: None   type: NodePort status:   loadBalancer: {} 

I also tried to find some logs:

core@helena-coreos ~ $ ./kubectl logs kubernetes-dashboard-1775839595-1h0lt --namespace=kube-system core@helena-coreos ~ $ 

I've got a really hard time to figure out why things are pending

Already thanks in advance.

回答1:

You don't have a scheduler running so it can't schedule any containers.

回答2:

The other possibility is that you have no resources in the cluster and the scheduler fails to schedule the Dashboard UI. If this is true you can see this in cluster events (kubectl get events --namespace=kube-system).
