Kubernetes is a highly extensible framework, where each of the cluster services can be customized depending on the use case. The extensibility also comes from the standardization of interfaces for various infrastructure components like compute/runtime, network or storage using the CRI, CNI, CSI etc., To get a clear understanding or to make a comparative study of various available options is only possible by trying each. To try these options, we require a multi-node cluster or more than one cluster. The platforms such as Raspberry-Pi, LePotato presents itself a viable option to build such multi-node home grown clusters as Kubernetes can be easily compiled and deployed on ARM architectures. In this talk, Harshvardhan Karn and Sumit Lalwani will present the usage of Raspberry-Pi, LePotato to evaluate the different CNI options like calico, flannel, cilium.
