Transcript

Welcome to practical guide to canary deployments. Unlike some other work that I did...tutorials, workshops, and so on and so forth, that were very focused on a single tool, this time I will focus more on a process.

We're going to try to figure out how to do canary deployments inside of Kubernetes. Because Kubernetes is everywhere now, I will assume that you are using Kubernetes. But outside of that, we are going to try to figure out which tools to use, but all serving as the process itself, not for the sake of learning a specific tool. And during that process, we are going to decide which tools to use and why to use them and the end result will be a fully operational canary deployments process that you will be able to plug into any CI/CD tool or any tool that orchestrates the lifecycle of your application.

So we will definitely choose some tools that we will use in a process.
And those tools will be revolving around Istio. I will explain why Istio a bit later.

So we will use Kubernetes and Istio for canary deployments, but the end result will be agnostic to the tool that will orchestrate your processes. We will most likely also have to choose one or two additional tools. Which tools we'll choose is yet to be discovered.

For now just think of this as being a practical guide to a specific process. And that process today is canary deployments in Kubernetes.

Canary Deployments To Kubernetes Using Istio: Why Did We Do Such a Course?

Drawing by Sara Farcic

A while ago, we (Viktor Farcic and Darin Pope) thought it would be a good idea to add an out-of-the-box option to use canary deployments in Jenkins X. We should have finished it by now, and yet we did not even start working on it. Instead of just adding it to Jenkins X, we spent considerable time exploring the subject.
