Deploy Kubernetes Cluster via Kubespray with Kata Container support on OTC

Kata Containers

The following guide will help you to install a 2-node Kubernetes cluster with Kubespray and providing Kata Container support. The cluster will consist of one master server which will be built on ECS (Elastic Cloud Server) and one node which will be built on BMS (Bare Metal Server). BMS is being used due to a current limitation of ECS on OTC, the ECS does not support nested virtualization which would be required for Kata runtime.
