After an initial `kubeadmn` deployment has been scheduled, it is time to deploy a CNI-enabled SDN. We have selected **Calico**, but have also confirmed that this works for Weave, and Romana. For Calico version v2.0, you can apply the provided [Kubeadm Hosted Install](http://docs.projectcalico.org/v2.0/getting-started/kubernetes/installation/hosted/kubeadm/) manifest:
```
kubectl apply -f http://docs.projectcalico.org/v2.1/getting-started/kubernetes/installation/hosted/kubeadm/calico.yaml
kubectl create -f http://docs.projectcalico.org/v2.1/getting-started/kubernetes/installation/hosted/kubeadm/1.6/calico.yaml
```
**PLEASE NOTE:** For Calico deployments using v2.0, if you are using a 192.168.0.0/16 CIDR for your Kubernetes hosts, you will need to modify [line 42](https://gist.github.com/v1k0d3n/a152b1f5b8db5a8ae9c8c7da575a9694#file-calico-kubeadm-hosted-yml-L42) for the `cidr` declaration within the `ippool`. This must be a `/16` range or more, as the `kube-controller` will hand out `/24` ranges to each node. We have included a sample comparison of the changes [here](http://docs.projectcalico.org/v2.0/getting-started/kubernetes/installation/hosted/kubeadm/calico.yaml) and [here](https://gist.githubusercontent.com/v1k0d3n/a152b1f5b8db5a8ae9c8c7da575a9694/raw/c950eef1123a7dcc4b0dedca1a202e0c06248e9e/calico-kubeadm-hosted.yml). This is not applicable for Calico v2.1.

It is important to call out that the Self Hosted Calico manifest for v2.0 (above) supports `nodetonode` mesh, and `nat-outgoing` by default. This is a change from version 1.6.
## Setting Up RBAC
Kubernetes >=v1.6 makes RBAC the default admission controller, OpenStack Helm does not currently have RBAC roles and permissions for each component so we relax the access control rules:
``` bash
kubectl update -f https://raw.githubusercontent.com/openstack/openstack-helm/master/tools/kubeadm-aio/assets/opt/rbac/dev.yaml
```
## Preparing Persistent Storage
Persistent storage is improving. Please check our current and/or resolved [issues](https://github.com/att-comdev/openstack-helm/issues?utf8=✓&q=ceph) to find out how we're working with the community to improve persistent storage for our project. For now, a few preparations need to be completed.
