# Provisioning Pod Network
We chose to use CNI - [weave](https://www.weave.works/docs/net/latest/kubernetes/kube-addon/) as our networking option.
Download the CNI Plugins required for weave on each of the worker nodes - `worker-1` and `worker-2`
`wget https://github.com/containernetworking/plugins/releases/download/v0.7.5/cni-plugins-amd64-v0.7.5.tgz`
Extract it to /opt/cni/bin directory
`sudo tar -xzvf cni-plugins-amd64-v0.7.5.tgz --directory /opt/cni/bin/``
Deploy weave network. Run only once on the `master` node.
`kubectl apply -f "https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')"`
Weave uses POD CIDR of `10.32.0.0/12` by default.
## Verification
List the registered Kubernetes nodes from the master node:
```
master-1$ kubectl get pods -n kube-system
```
> output
```
