You must install a pod network add-on so that your pods can communicate with each other when they are on different hosts.
**It is necessary to do this before you try to deploy any applications to your cluster.**
Several projects provide Kubernetes pod networks.
You can see a complete list of available network add-ons on the [add-ons page](/docs/admin/addons/).
Several projects are available that enable Kubernetes pod networks including Calico, Romana and Weave. Some may also support [Network Policy](/docs/user-guide/networkpolicies/). See the [add-ons page](/docs/admin/addons/) for a complete list of available network add-ons.
By way of example, you can install [Weave Net](https://github.com/weaveworks/weave-kube) by logging in to the master and running:
# kubectl apply -f https://git.io/weave-kube
daemonset "weave-net" created

You should only install one pod network per cluster.
Once a pod network has been installed, you can confirm that it is working by checking that the `kube-dns` pod is `Running` in the output of `kubectl get pods --all-namespaces`.
