Registering an Azure Kubernetes Service Cluster with Argo CD

by

Argo CD is a GitOps operator and the goal of it is to be able to deploy apps to Kubernetes. In the majority of cases, we want to use Argo CD to deploy apps to many clusters.

Argo CD itself is deployed as a set of pods on a Kubernetes cluster. By default with an Argo CD deployment, the cluster it is running on is set as “in-cluster” (https://kubernetes.default.svc). When apps are configured for deployment a Kubernetes Cluster under Destination is required. They can be deployed to either the “in-cluster” K8s cluster or an external K8s cluster.

In order to deploy apps to an external Kubernetes cluster, you will need to register an external K8s cluster with Argo CD.

If you want to see the clusters you have registered with your Argo CD one way is through the web UI. Once you log in navigate to Settings and then Clusters to see them.

You can also see the clusters you have in the Argo CD CLI. To use the Argo CD CLI you need to log into the Argo CD API Server as shown in the following screenshot.

To see what clusters are registered from the CLI you can run

argocd cluster list

You will notice that you will only see the In-Cluster K8s cluster until you add an external one. Also, note that you are not able to register a new K8 cluster in the Argo CD web UI. You can only register a new K8s cluster from the Argo CD CLI. Within the Argo CD web UI you can delete the default in-cluster K8s cluster. This is not recommended.

If you click on the In-Cluster K8s cluster you can modify some settings of the in-cluster K8s cluster in the Argo CD web UI such as the name of it and its namespace. Not useful when you want to have more control over the settings around the K8s cluster you will be deploying apps to.

In my example, my Azure subscription has two AKS clusters. You can see this in the following screenshot. The arriving-gelding-k8s cluster is my In-Cluster object in Argo CD. The selected-worm-k8s is not my In-Cluster so I want to add this one to my Argo CD.

To add the new external cluster run use the following steps.

Step 1: Add your target K8s cluster to ArgoCD via the context in your kubectl config.

-For AKS you can simply log into your Azure subscription from VS Code on your computer and then run

 az aks get-credentials –resource-group RGNAME –name AKSCLUSTERNAME

This will add the context for your AKS cluster to your kubeconfig file.

-For the process on your setup refer to the following link as it may differ:  https://kubernetes.io/docs/tasks/access-application-cluster/configure-access-multiple-clusters

Step 2: List the K8 cluster contexts in your current kubeconfig file to ensure your target cluster has been added. Do this by locally running:

kubectl config get-contexts -o name

Step 3: Install a Service Account (argocd-manager), into the kube-system namespace of your kubeconfig file context:

argocd cluster add CONTEXTNAME

It will look like this:

After completing the previous steps you can run argocd cluster list again or go into the portal. You will see your new cluster added.

That wraps up this blog post. Now you should be able to deploy to more than just your In-Cluster Kubernetes cluster. Check back soon for more posts on Argo CD, GitOps, Kubernetes, and Azure topics.

Deploy App to Azure Kubernetes Service via Argo CD

by

In my last post on Argo CD with AKS, I mentioned the next post would explore deploying an app via Argo CD. Well, in this post we are going to do just that. I am going to walk through deploying an app from Argo CD to AKS. Note this same process would work for any Kubernetes cluster. This is not going to be a long post as the process is straightforward.

First of all, you can deploy an app from the Argo CD web UI or CLI. Ready your application in a Git-based repository. It does not matter what source control system you use for your repository as long as it is Git-based. You can use Azure DevOps, Gitlab, Bit Bucket etc. In my case I use GitHub. To deploy an app you need to point to a Git repository of either K8s manifest, Helm, or Kustomize. In this blog post I am going to keep it simple and use the Hello K8s app from Paul Bouwer. Ok, now let’s jump in.

Here are the steps for Deploying an App to Argo CD within the Web UI:

  1. In the Argo CD web UI ensure you are on the Applications page
  2. Click the + NEW APP button
  3. Give the app the name hellok8s, use the project default (I used a dev project in my example), select Automatic for the sync policy, check AUTO-CREATE NAMESPACE
  4. On Source for the Repo URL use https://github.com/paulbouwer/hello-kubernetes.git & select deploy/helm/hello-kubernetes for the path
  5. For the DESTINATION select https://kubernetes.default.svc for the Cluster URL and use hellok8s for the namespace
  6. Leave all the defaults under HELM
  7. Click the CREATE button at the top of the UI

Once the app is deployed it will look like this:

You can view the resources in AKS now. In the following screenshot you can see the deployment, pods, and service of a load balancer type.

You can also speed things up by deploying your app via the Argo CD CLI. This will accomplish the same goal as you would deploying the app via the Argo CD Web UI.

Deploying an App to Argo CD from the Argo CD CLI:

argocd app create hellok8s –repo https://github.com/paulbouwer/hello-kubernetes.git –path deploy/helm/hello-kubernetes –dest-server https://kubernetes.default.svc –dest-namespace default

That wraps things up for this post. Check back soon for more posts on Argo CD, GitOps, Kubernetes, and Azure topics.

Argo CD Course Published on Pluralsight

by

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:

  1. Argo CD’s core concepts and architecture.
  2. An overview of Containers, Kubernetes, Helm, Kustomize, GitOps, and how these work with Argo CD.
  3. 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.
  4. How to deploying and manage Applications with Argo CD.

Check out the course here: https://app.pluralsight.com/library/courses/argo-cd-getting-started

This is my 1st course in the Kubernetes Tooling and Techniques path on Pluralsight. I am working on another course for this path. This path focuses on the additional tools and techniques that you can integrate with your Kubernetes operations to improve efficiency, scalability, and a whole host of other factors. There are some other great courses in the Kubernetes Tooling and Techniques path.
