Using 1.6.6 release for all

I am trying to deploy K8s federation using this guide

I am using below command to create federation components in k8s cluster.

kubefed -v=9 init fellowship    --dns-provider="kube-dns"     --dns-zone-name="example.com"  --host-cluster-context="kubernetes-admin@kubernetes"   --api-server-service-type="NodePort"     --api-server-advertise-address="xx.yy.zz.aa" --etcd-persistent-storage=false   --kubeconfig="/etc/kubernetes/admin.conf"

this is what happening

federation-system   fellowship-apiserver-1032646596-pc3bh            2/2       Running            0          14m
federation-system   fellowship-controller-manager-2770733854-g593b   0/1       **CrashLoopBackOff**   7          14m

**an logs are as below** .

Any guess what is happening here , am I missing something ?
