Setting up an OpenStack lab is out of scope for this tutorial. Assuming that you have a lab, you will need to create 1+n VMs: one to be configured as the Kubernetes master node, and "n" to be considered as Kubernetes worker nodes. We will create 3 Kubernetes worker nodes for this tutorial because we want each of our SDN-Cs to appear on a different VM for resiliency.

There are some changes committed in OOM repo. Two new pods are added: dmaap and ueb-listener. We observed issue with SDNC pods deployment using one master and three worker nodes. We were able to deploy SDNC with latest OOM using one master and four worker nodes.

The examples here will use the OpenStackClient; however, the Openstack Horizon GUI could be used. Start by creating 4 VMs with the hostnames: k8s-master, k8s-node0, k8s-node1, and k8s-node1. Each VM should have internet access and approximately:
