ApplicationSet Addons

Overview

Let's apply Apps of Apps pattern using Argo ApplicationSet.

Prerequisites

  • Kubernetes cluster
kind create cluster --config kind-1.29.yaml
  • ArgoCD installed
kubectl create namespace argocd
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

Repository structure

Here's a brief description of the main directories and files:

applications/: This directory contains the main Helm chart for App of Apps Pattern (v1 approach). The Chart.yaml file describes the chart and its version, and the values.yaml file specifies configuration values for the chart. The templates/ subdirectory contains template files that represents Argo Applications.

bootstrap/: This directory contains YAML files that are used to bootstrap ApplicationSets (v2 approach). Together with bootstrap.yaml file, these files are used to provision ApplicationSets.

charts/: This directory contains Helm charts for various add-ons or dependencies. Each subdirectory (like addons/, capsule-system/, ingress-nginx/, etc.) represents a different add-on, and contains its own Chart.yaml and values.yaml files.

clusters/: This directory contains configuration specific to different Kubernetes clusters where application might be deployed. The dev/, in-cluster/, and prod/ subdirectories correspond to different environments (development, production, etc.). You can use this directory to override values based on the add-ons+environment combination.

kind-1.29.yaml: This file is a configuration file for running a local Kubernetes cluster using Kind.
