Kubernetes Scheduling Features or How Can I Make the System Do What I Want? [I] - Marek Grabowski & Wojciech Tyczynski, Google
Each user has her own set of requirements and constraints on where their Pods should be placed in a cluster. Some want to increase utilization, thus they want to pack Pods as densely as possible. Other want to maximize reliability, so they spread the Pods as thinly as they can.

Another one may have Pods that interfere with each other, e.g. by writing a lot to a local disk and don't want to put those on a single Node.

During this talk I'll tell what features are present in the default Kubernetes scheduler that can help you to accomplish all those things and more.

Autoscaling in Kubernetes [I] - Marcin Wielgus, Google
One of the nicest features of Kubernetes is its ability to automatically adjust the cluster size and the number of pod replicas to the current traffic and load. During this talk I will explain what is the current state of pod and node autoscaling in Kubernetes, how it exactly works, what metrics can be used to drive autoscaling, and what are the best practices to apply it in production.

Autoscaling a Multi-Platform Kubernetes Cluster Built with kubeadm [I] - Lucas Käldström, Upper Secondary School Student - Individual Maintainer
Does Kubernetes run on any architecture other than Intel/AMD64? Yes it does, since v1.3.0.
Lucas Käldström (@luxas), a general upper secondary school student, added support for ARM and ARM 64-bit to the core codebase earlier this year. Kubernetes is all about letting you choose the container runtime, the operating system, the environment (cloud vs bare metal) etc., so why wouldn’t you like to choose CPU architecture as well?

The talk demonstrates Kubernetes’ multi-architecture features in a very practical manner: by having a 10-node cluster of credit-card-sized devices with three architectures (amd64, arm and arm64) in front of the audience. The cluster is deployed with kubeadm. For the demo, a cross-platform nginx workload will be created from the dashboard, deployed to all nodes regardless of architecture, monitored via an auto-updating grafana dashboard and autoscaled by a Horizontal Pod Autoscaler while traffic is generated against the cluster’s Ingress controller. And just to make things more exciting, a node’s power cable may be unplugged by a volunteer from the audience, at any time during the heavy traffic to demonstrate Kubernetes’ auto-healing functions.

Kubernetes Cluster Federation: How to Write a Federated Controller? [A] - Madhu C.S. & Nikhil Jindal, Google
Extensibility is one of the major selling points of Kubernetes. Cluster Federation is built on the same spirit, but the tooling provided in the form of libraries and framework to build federated controllers is quite different than the tooling provided to build Kubernetes controllers. In this talk, we will show you the tools and techniques provided by Cluster Federation to write your own federated controllers. We will also show you the steps involved in building a federated controller by building one during the talk.
