pods not starting in replication controller

8/4/2016

hello I was trying to run Sample file from this page: http://kubernetes.io/docs/user-guide/replication-controller/operations/

and I have replication controller but no pods:

$ kubectl describe  rc frontend-controller
Name:       frontend-controller
Namespace:  default
Image(s):   redis
Selector:   app=frontend
Labels:     state=serving
Replicas:   0 current / 2 desired
Pods Status:    0 Running / 0 Waiting / 0 Succeeded / 0 Failed
No volumes.
No events.

when I try kubectl get events there is no information about it. I can create standalone pod but any replication controller doesn't work

Where can I find some useful log to debug it (systemctl status kubelet on master node doesn't say anything about it) Maybe I can set Kubernetes to more verbose ?

Edit:

component statuses

$ kubectl get cs

Ok I fixed it. It turns out that I put a file kube-controller-manager.yaml to wrong location(after recreation of cluster with file placed in /etc/kubernetes/manifests/kube-controller-manager.yaml it's ok ), thanks for help.
