We all live in difficult times. Coronavirus pandemic is raging. There is the danger of a global crisis. Many of us are confined to our homes.
I believe that this is the moment when we should re-evaluate our priorities on many different levels, professional being one of them. We should all take this opportunity of being at our homes to raise our profile and become more proficient at our jobs. We cannot know for sure what the future brings. But, whatever it is, it's always best to be prepared. Professionally, the best way to be ready for turbulent times is to learn.

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.
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.
Your cluster is bound to run quite a few third-party applications. They need to be installed and managed somehow. This article offers one possible way to install and maintain third-party applications using Jenkins X Apps. We'll use Istio as an example of such an application and try to figure out how to convert its official Helm charts into Jenkins X Apps and, during that process, explore some of the benefits they provide.
What's wrong with jx create cluster and jx install commands? Why do we need a different way to install, manage, and upgrade Jenkins X? Those are ad-hoc commands that do not follow GitOpts principles. They are not idempotent (you cannot run them multiple times and expect the same result). They are not stored in Git, at least not in a form that the system can interpret and consume in an attempt to converge the desired into the actual state. They are not declarative.
