Advanced Networking Patterns
In this lab we’ll be doing a deep dive into Kubernetes Networking. Starting by building a strong understanding of the various mechanisms supporting Kubernetes networking abstractions and working through several real world examples which will enable you to architect, build and maintain a production-grade system.
Networking deep dive
In this session we’ll follow the life of a network packet entering the Kubernetes cluster, and how Kubernetes mechanisms support that journey. We’ll explain how various configurations impact the performance of your cluster and various considerations you need to take when architecting it.
After understanding the fundamentals, we’ll cover several real world examples and show you various ways to architect your services. We’ll cover using NodePorts for cluster debugging purposes, to using namespaces for basic isolation and more.
Kubernetes has built in mechanisms to isolate workloads and ensure levels of isolation between various components necessary in a production-grade system. We’ll be focusing on Kubernetes Network Policies and explain how to integrate them into your system in a flexible manner.
Ingress mechanisms allow you to expose your cluster to the world. We’ll be demonstrating few of the most popular Ingress controllers, and working through a real world example where we expose a real microservice system through the API.
Debugging network Issues
Finally, we’ll introduce a set of useful tools to debug Kubernetes network issues and practice a few failure scenarios to ensure we are able to use the knowledge gained throughout the workshop to troubleshoot and resolve real systems.
