GitOps, Argo, and Azure Kubernetes Service - Part 2

In this post on ArgoCD I am going to walk through deploying an app from ArgoCD to AKS.

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. in our case we will use Azure DevOps to deploy an app. we 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 simple nginx  application

Demo Steps:

1- First step, we need to connect ArgoCD wtih Azure Devops
2- In the Argo CD web UI go to Settings> Repositories > CONNECT REPO USING HTTPS

3- Enter Git details

You have to get the credentials from Azure devops as the following - Read more -

4- Click on Connect

5- Click on context icon > Create Application

5- Enter Application details as the following

Automatic Pruning: By default (and as a safety mechanism), automated sync will not delete resources when Argo CD detects the resource is no longer defined in Git
Self-Healing: By default, changes that are made to the live cluster will not trigger automated sync

instead, you can update/create the application though manifest file/CLI

6- Click on Create

7- The Application got created  and synced now

8- Done :)

Now, you can fully manage the application from Argo web portal or Argo CLI, you can check the logs, execute command on the pod, delete, scale,,,etc

As you can see from the snippet below, we can view and edit the deployment manifest file

Note: since we have enabled Automatic Pruning ANY CHANGES MADE AND NOT DEFINED IN GIT WILL BE DELETED/IGNORED
Consider this if you have enabled auto scale on the deployment!

so, let's made the changes from the repos, I will scale it from 4 to 8

ArgoCd triggered the changes and it will apply the changes directly.

let's check the logs of the pod

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