Kubernetes double IP in different nodes

11/13/2017

after using k8s on GKE for a couple of months I've decided to install my own cluster. Now, I've two ubuntu VMs and one of them is the kube-master and the second one is a node. Cluster run as I expect and I can see nodes (kube-master is a node also) when run kubectl get nodes. I've launched one pod each VMs bat I'm experiencing an issue both pod have the same IP. Can anybody help me to resolve this issue? I'm using flannel as network plugin atm. Thanks in advance

Update

I've found the solution, thanks kubernetes group on slack. I didn't install the [cni][1]plugin so the kubelet didn't know the subnetwork status. I installed the plugin using this guide, made a configuration file following that. Restarted the kubelete service finally I saw the cluster was work as I expected.
