After installing calico networking tool for kubernetes

things are just not stable

I have run this one

kubectl create -f kubectl apply -f https://docs.projectcalico.org/v3.0/getting-started/kubernetes/installation/hosted/kubeadm/1.7/calico.yaml

​

​

adminr@k8smaster:~$ kubectl get pods -o wide --all-namespaces
