Argo CD Course Published on Pluralsight

December 1, 2021 by sbuchanan

Yesterday my 12th course on Pluralsight was published! This course is “Getting Started with Argo CD“. In this course, you’ll learn the ins and outs of Argo CD a GitOps Operator tool, its core concepts, architecture, and how to use it with Kubernetes clusters so you can get started using it.

I am really excited about this course because it gave me a chance to continue sharing my GitOps and Kubernetes knowledge. You can view this course as a continuation of my “GitOps: The Big Picture” course. My GitOps course educates you on what GitOps is. This Argo CD course shows GitOps and a GitOps Operator in action!

Many organizations today have adopted cloud & Kubernetes. Organizations multiple production Kubernetes clusters online often across multiple clouds the complexity of management increases. GitOps has risen as a pattern used to reduce the complexity of managing Kubernetes clusters and cloud-native applications. Argo CD is a GitOps Operator that can help with the management of Kubernetes and deployment of applications to it. Some of the major topics that I covered in the Argo CD course include:

Argo CD’s core concepts and architecture.
An overview of Containers, Kubernetes, Helm, Kustomize, GitOps, and how these work with Argo CD.
What it takes to deploy and operate Argo CD including areas such as user management, secrets, webhooks, monitoring and more, as well as how to use the Argo CD API server, Web UI, and use its command line interface.
How to deploying and manage Applications with Argo CD.

Get started with Argo CD & Azure Kubernetes Service

December 1, 2021November 4, 2021 by sbuchanan

As Kubernetes adoption continues to grow so does GitOps. GitOps has been increasing in adoption and popularity among enterprises at a fast rate as well. Here is what GitOps is: “GitOps is an operating model pattern for cloud-native applications & Kubernetes storing application & declarative infrastructure code in Git as the source of truth used for automated continuous delivery.” GitOps puts Git at the center of continuous delivery making git the Source of Truth describing the desired state of your entire system. For a deeper dive into GitOps check out my GitOps course on Pluralsight here: https://app.pluralsight.com/library/courses/gitops-the-big-picture

In the GitOps model, you need GitOps operators. GitOps Operators are software agents that continuously monitor your apps running on your Kubernetes clusters comparing the live state of your app against the desired state you have defined in your Git repository. These GitOps Operators ensure the desired state is in place on your Kubernetes clusters performing create, update, delete activities on your Kubernetes clusters as needed.

This is where Argo CD comes into the picture. Argo CD is one of the top GitOps Operators. It provides declarative, continuous delivery to your Kubernetes clusters. It was created by a team at Intuit in 2018 and later open-sourced. I am going to write a few blogs exploring the use of Argo CD with AKS. This will be the first of the series walking through the deployment of Argo CD to AKS. In the next post, we will deploy an app to Kubernetes using Argo CD and see where the topic goes from there. Now let’s dive into deploying Argo CD to AKS. Here are the steps:

-DEPLOYING ARGO CD ON AKS-

Log onto the Azure portal (https://portal.azure.com)

Launch Azure Cloud Shell

Connect to your AKS cluster from the Azure Cloud Shell by running the following:

# Set your subscription

az account set –subscription YOURSUBSCRIPTIONIDHERE

# Connect to your KS cluster

az aks get-credentials –resource-group YOURRESOURCEGROUPNAME –name CLUSTER NAME

Next let’s create a namespace for Argo CD to deploy all of its components in. To do this run:

kubectl create namespace argocd

Next we can install Argo CD into the new namespace we created. We will reference Argo CD’s GitHub repository for the latest Argo CD operator. Run the following:

kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

You should see the following:

You should end up with many objects in the Argo CD namespace.

By default, the Argo CD is not accessible externally. It is deployed with a service type of ClusterIP.

Leaving it at ClusterIP is fine but for the purposes of this blog/lab and getting started lets change this so we can easily access the ArgoCD Server website. # Change the argocd-server service type to LoadBalancer. To do this run the following:

kubectl patch svc argocd-server -n argocd -p ‘{“spec”: {“type”: “LoadBalancer”}}’

Now you will be able to see that the argocd-server service type has been changed to a LoadBalancer type. This means that it now has a public Azure load balancer attached to it with an external IP.

NOTE: This is not recommended in production environments. Only use in a lab or dev environment. In production environments, it is recommended to use an ingress for the Argo CD API server that is secured.

Argo CD auto generated a password during the deployment. We need to get the Argo CD password so we can log into it. To get the password run the following:

kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath=”{.data.password}” | base64 -d && echo

You will see the password in readable format so you can copy it such as shown in the screenshot.

Note the default Argo CD username is admin.

To access the Argo CD web portal you need to access the Argo CD API Server. To do this you can either do this from the external IP of the argo-cd object or the via the Argo CD CLI using the following:

argocd login <ARGOCD_SERVER>

The Argo CD web portal will look like:

That’s it! You have Argo CD deployed on your AKS cluster. In the next post, I will walk through deploying a simple app to your Kubernetes cluster via Argo CD.

New ebook – Azure Arc enabled Kubernetes for Multicloud on O’Reilly

February 22, 2021 by sbuchanan

After 6 books with many authors from Packt, APress, & Sams/Pearson I finally had the chance to author a book with O’Reilly. This is an ebook so it can be found and read on the O’Reilly online platform.

It is a great platform that I use personally for my own learning. On their platform, you can find ebooks, books across many publishers (most of my books are on there), video training, and even live training.

This book brings together 4 exciting technologies/topics including Azure, Kubernetes, GitOps, and multi-cloud. The book is shorter than my typical books since it is an ebook. It is only 35 pages and is designed for fast & easy consumption to get an overview of the technology and get an early start.

In this book, we take a journey into one of Microsoft’s newest cloud services Azure Arc enabled Kubernetes (Arc K8s). We explore what Azure Arc K8s is, how it extends the Azure control plane to Kubernetes clusters to manage, secure, and govern them, as well as how GitOps sits are the core of application deployment to Kubernetes clusters and a driver of consistent configuration management for Kubernetes clusters.

Azure Arc is a Microsoft product that promises to extend the Azure control plane for Kubernetes across multiple clouds and on-premises, but how does it do this? In this ebook we will dissect Azure Arc K8s and how it becomes a secret weapon for managing Kubernetes clusters across on-premises, multiple clouds, and regardless of your own rolled Kubernetes clusters or managed services based Kubernetes clusters such as GKE, EKS, etc. I also want to give a shout-out to Michael Levan for reviewing this ebook!

Key Areas from the ebook include:

-Understand the new management challenges that multicloud brings
-Learn how Azure Arc drives consistent governance, security, and management across multicloud
-Gain valuable insights into Microsoft’s Azure ARM control plane for Kubernetes
-Learn how Azure Arc manages Kubernetes clusters across on-premises and multiple cloud deployments
-Explore the GitOps technology pattern and operating model for cloud native applications and Kubernetes
-Use Azure Arc-enabled Kubernetes and GitOps to deploy configurations and applications to Kubernetes clusters

Check out the new ebook here: https://www.oreilly.com/library/view/azure-arc-enabled/9781098102647

Also keep an eye on my O’Reilly author page here https://www.oreilly.com/pub/au/8326 for any future projects I have with them.

CloudSkills.fm Podcast: Cloud Native, Azure Arc, DevOps, GitOps, Kubernetes, and Azure

February 19, 2021 by sbuchanan

Recently I had the honor to be a guest on my friend and fellow Microsoft MVP Mike Pfeiffer’s Cloudskills.fm podcast again! This was episode is “106: Steve Buchanan on Cloud Native, DevOps, GitOps, Kubernetes, and Azure“. I was excited to be a guest again on the CloudSkills podcast and catch up with Mike.

On this new episode, we had a chance to talk about a variety of topics like leveling up your career, what I have been up to, diversity and inclusion in the tech, of course Azure, Azure Arc, DevOps, Kubernetes, GitOps, we even touched on SAP on Azure, among other insights.

You can listen to the podcast episode 106 right here on my blog:

GitOps: The Big Picture

February 3, 2021 by sbuchanan

There is another wave coming. This wave is GitOps. GitOps is a technology pattern and operational framework. It is often used for Kubernetes however is really for cloud-native applications in general. Being that a large amount of cloud-native applications these days are designed and built to run on Kubernetes it is no surprise that GitOps is commonly adopted in Kubernetes environments. If you are running Kubernetes or looking at it chances are you may have heard of GitOps. This is how I define GitOps:

“GitOps is an operating model pattern for cloud native applications storing application & declarative infrastructure code in Git as the source of truth used for automated continuous delivery.”

Well, that sums up with GitOps is but it still is a mouthful and can take a bit to wrap ones head around it. In a nutshell GitOps is shifting everything to code, storing everything in Git, making Git the source of truth, and using an operator deploy what is described in Git in your environment including the application and the configuration. With GitOps you describe the desired state of your entire system and GitOps makes it so. It simplifies operations and makes the experience for developers much better allowing them to work out of a tool they are familiar with (Git). Here is a basic sample diagram to give you a visual idea about what GitOps is and how it works:

So in the case of Kubernetes you would have your app code in Git, your container images in Git, and your Kubernetes manifest files. Now there is more to it and how it works but we will not get into all of that in this blog post. This is a good Segway to purpose of this blog post.

The purpose of this blog post is that I just dropped my 7th Pluralsight course GitOps: The Big Picture! This was a fun course to build as I am passionate about and like working with Containers, Kubernetes, and cloud.

A quick shoutout to both Fellow Microsoft MVP/Pluralsight Author Tim Warner and Jason Alba for amplifying my new course!

This course teaches the fundamentals of GitOps, the need for GitOps, GitOps architecture, GitOps workflow, GitOps principles, practices, & tooling such as Flux, Argo CD, AND Jenkins X. Also in this course, GitOps: The Big Picture, you’ll learn what it takes to adopt GitOps. First, you’ll explore what GitOps is and its benefits. Next, you’ll discover GitOps Tooling NS Architecture. Finally, you’ll learn how to use GitOps Workflows. When you’re finished with this course, you’ll have the skills & knowledge of the GitOps framework needed to take the next steps with GitOps.

In the course I give a couple of demos so you can see GitOps in action. The first demo is on “deploying an application using Argo CD” and the second demo is on “GitOps in Action with Azure Arc Enabled Kubernetes using Flux”. Another interesting fact about GitOps is we are starting to see the major cloud providers bring GitOps into their offerings such as Azure Arc and or couple GitOps with their services like with GCP GKE as well as create content on using GitOps with their managed Kubernetes services like with AWS EKS.

GitOps is going to continue to grow right along with the continued growth of Containers, Kubernetes, and Cloud. I am all in and you will see blogs, books, courses, speaking at events, and more from me around GitOps as I continue on my personal journey with it.
