Continuous Delivery (CD) Is Not What Some Are Trying To Sell You

Since the increase in popularity of continuous delivery (CD), there was an increase in the number of tools marketed as CD solutions. That’s normal. It is only natural for software vendors to ride the waves. They need to sell, and there’s nothing better to sell than whatever is popular at a given moment. Continuous delivery is one of those "popular" waves.

A video version of the same post is available in The DevOps Toolkit Series YouTube channel.

On the surface, there is nothing wrong with buying tools that solve problems. You have a problem, a vendor has a solution, you buy it, they earn money, and you have a good return on investment. Everybody wins, except when the tool does not do what it’s supposed to do. That’s when we run into issues.

What Is GitOps And Why Do We Want It?

GitOps is nothing new. Or, to be more precise, the principles of GitOps existed long before the term was invented. But hey, that’s the pattern in our industry. It is the fate of all good practices to be misunderstood, so we need to come up with new names to get people back on track. That is not to say that we are in a constant loop. Instead, I tend to think of it as a periodic reset trying to eliminate misinterpretations. GitOps is one of those resets. It fosters the practices and the ideas that existed for a while now and builds on top of them.

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.

What Is Jenkins X Boot And Why Do We Need It?

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.

“The DevOps 2.6 Toolkit: Jenkins X” is out

After nine months of work, I managed to finish the latest book in The DevOps Toolkit Series. We’re at the seventh book, and this time it’s all about Jenkins X.

The book is called The DevOps 2.6 Toolkit: Jenkins X and the following few paragraphs is how it starts.

Running Serverless Deployments With Jenkins X, Gloo, And Knative

Serverless deployments are gaining traction. Today, we have quite a few choices for converting our applications into serverless inside Kubernetes cluster. One of those, my favorite, is Knative. We’ll explore how we can combine it with Jenkins X to create a fully automated continuous deployment pipeline that deploys serverless applications.
