Kubernetes deployment (KUD) is a project that uses Kubespray to bring up a Kubernetes deployment and some addons on a provisioned machine. As it already part of EMCO it can be effectively reused to deploy the K8s App components(as shown in fig. II), NFV Specific components and NFVi SDN controller in the edge cluster. In R2 R4 release KuD will be used to deploy the K8s addon such as Virlet, OVN, NFD, and Intel device plugins such as SRIOV in the edge location(as shown in figure I). In R3 release, KuD will be evolved as "ICN Operator" to install all K8s addons. For more information on the architecture of KuD please find the information here.
