Kubernetes and Istio service mesh workshop materials

In the past year, I have done multiple workshops on Kubernetes, Istio and cloud-native development. As part of my workshops I usually start with theory and explain the concepts using slides, show some demos, but then it's on you, the participant to try out the technology yourself.

Master the Kubernetes CLI (kubectl) - Cheatsheet

This Kubernetes CLI (kubectl) cheatsheet contains the most common commands you will use when working with Kubernetes clusters and Kubernetes resources. If you're working with Kubernetes on daily basis or if you're just learning about Kubernetes you will run into a set of commands that are used often than the other commands. The ones used more often are also usually easy to remember (especially if you're typing them out multiple times a day).

What are sticky sessions and how to configure them with Istio?

The idea behind sticky sessions is to route the requests for a particular session to the same endpoint that served the first request. That way to can associate a service instance with the caller, based on HTTP headers or cookies. You might want to use sticky sessions if your service is doing an expensive operation on first request, but later caching the value. That way, if the same user makes the request, the expensive operation will not be performed and value from the cache will be used.

Zero Downtime Releases using Kubernetes and Istio

The idea behind zero downtime release is to release a new version of the service, without affecting any users — i.e., users don’t even know when a new version of the service is released.
