Serverless Kubernetes - Virtual Kubelet

How to use custom metrics in combination with the Kubernetes Horizontal Pod Autoscaler(HPA) to autoscale an application. Virtual nodes (virtual-kubelet) let you scale quickly and easily run Kubernetes pods on container Instances where you’ll pay only for the container instance runtime.

1. Serverless Kubernetes @vivek_sridhar
2. Agenda • Introduction to Kubernetes • Kubelet functions • Virtual Kubelet Architecture • Use - Cases • Demo - Deploying the app on Kubernetes & scaling app via HPA
3. Serverless Kubernetes no infrastructure to manage, starts in seconds, pay for consumption
4. How Kubernetes works 1. Kubernetes users communicate with API server and apply desired state 2. Master nodes actively enforce desired state on worker nodes 3. Worker nodes support communication between containers 4. Worker nodes support communication from the Internet Kubernetes control API server replication, namespace, serviceaccounts, etc. -controller- manager -scheduler etcd Master node Worker node kubelet kube-proxy Docker Prod Prod Containers Containers Worker node kubelet kube-proxy Docker Prod Prod Containers Containers Internet Internet
