Autoscale Your on-Premises Bare Metal Kubernetes Clusters - Shukun Song, Fujitsu Limited

On an on-premises bare metal Kubernetes cluster, autoscaling is a difficult task but important as it can increase the efficiency of resource usage to help organizations reduce cost, for example power consumption. In this talk, Shukun will introduce the idea of combining 3 projects, Cluster-API, Metal3-io and Cluster Autoscaler, to achieve autoscaling on a bare metal cluster. Metal3-io is a CNCF sandbox project which aims to provide a Kubernetes-style way to manage bare metal servers and Cluster-API, as a sub-project of Kubernetes, is developed to manage Kubernetes cluster lifecycle. Combining these projects, it is easy to manage bare metal infrastructure and build Kubernetes clusters on it. Machines and clusters are managed as Kubernetes resources and all the provisioning and deprovisioning work can be done automatically with just declaring or configuring those resources. Also, it is possible to combine Cluster Autoscaler as well to increase the efficiency of the physical resources, for example, concentrate applications deployment to some servers if the total usage of the cluster is low, to spare the unused resources. Shukun will introduce the detail of these projects, explain how they are interacting with each other and show how to use them.
