About this event

Hello Chicago Kubernauts!

We warmly invite you to join us for the next meetup where will dig into a couple interesting K8s topics.

Saba & Corey are going to team up and introduce writing serverless functions in Kubernetes. This talk provides a tutorial on developing serverless functions using OpenFaaS. It also features a demo of how they have utilized these functions for an event driven workflow at Relativity. OpenFaaS (https://github.com/openfaas/faas) is a framework that enables developers to run their small pieces of codes in form of functions wrapped in a Docker container in a Kubernetes cluster. The framework includes built in scheduling and monitoring. The talk will go over some of the benefits gained and challenges faced when developing using OpenFaaS.

Second, Drew from Tigera will present "Isle of Cats: K8s Networking Revealed." Kubernetes networking plug-ins and frameworks are necessary and integral to running K8s. This talk will explain how the two most common frameworks: Flannel and Calico work underneath the hood including the Calico and Flannel CNI plugins. He will then show some best practices and solutions to common gotchas with the goal of increasing the speed and reliability of your Kubernetes networking plane.
