Intro to Kubernetes and Service Mesh
In this workshop, you will learn about Kubernetes and service meshes. The first part of the workshop focuses on Kubernetes basics, such as pods, deployments, and services, where you will learn how to create deployments, scale them up and down, define volumes, mount secrets and config maps to containers, create readiness checks and more. In the second part of the workshop, you will learn about Istio service mesh. We will explain how to do zero downtime deployments, A/B tests, how to intelligently route traffic and handle failures. All this without writing any code or affecting your services running in production. Each section in the workshop will have exercises, where you can practically try out the concepts on your own, so don’t forget to bring your laptop!
Prerequisites:
In order to work with Kubernetes and Istio you will need access to a Kubernetes cluster. For the workshop purposes you will be running a cluster locally on your own computer. Note: if you have access to a cloud-managed cluster, you can use that as well.
Installing Kubernetes
There are a couple of options to install Kubernetes – the links below will take you to the instructions on how to install this on your own computer. Whichever option you pick, make sure you allocate at least 14 GB of memory and 4 CPUs in order for the cluster and Istio mesh to run smoothly.
Installing Istio
All examples, demos, and exercises are testing with Istio 1.2.2, however, you can also pick a later version if it’s available.
There are multiple ways to install Istio – the simplest one is to use Helm. The instructions on how to install Istio are here – look under Option 2 and use the demo configuration profile as this will install everything you will need during the workshop.
Workshop is going to be held in English.
