EKS Blueprints Add-ons

Welcome to the EKS Blueprints Add-ons repository.

This repository contains GitOps configuration which follows the ArgoCD App of Apps pattern. It demonstrates how EKS customers can leverage ArgoCD to easily bootstrap an EKS cluster with a wide variety of Kubernetes add-ons.

Usage

With the EKS Blueprints Framework

This repository can be used in concert with the Amazon EKS Blueprints framework. Please see the ArgoCD add-on documentation for details on how to easily bootstrap an EKS cluster with the add-on configuration contained in this repository.

With an Existing Cluster

To bootstrap an existing cluster, you must first install ArgoCD. Instructions for doing so can be found in the ArgoCD getting started documentation.

Configure an Application

Once ArgoCD is installed, create a new application.yaml file with the following configuration.

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: add-ons
  namespace: argocd
spec:
  project: default
  source:
    repoURL: https://github.com/aws-samples/eks-blueprints-add-ons.git
    targetRevision: HEAD
    path: chart
    helm:
      release: add-ons
      values: |
        cluster-autoscaler:
          enable: true
        metrics-server:
          enable: true
  destination:
    server: {{ .Values.destinationServer | default "https://kubernetes.default.svc" }}
    namespace: argocd

Note that you specify which add-ons should be installed by supplying values in the spec.source.helm.values map configuration. This example will only install cluster-autoscaler and metrics-server. To view available add-ons, visit the add-ons directory.

Deploy the add-ons

Apply the yaml to bootstrap the cluster.

kubectl apply -n argocd -f application.yaml

Repo Structure

The structure of this repository follows the ArgoCD App of Apps pattern. The configuration in this repository is organized into two directories: chart and add-ons.

├── chart
└── add-ons

Chart

The chart directory contains a Helm chart which represents the root Application for the ArgoCD App of Apps pattern. This Helm chart in turn deploys additional ArgoCD Application resources which represent additional add-on Helm charts.

│   └── aws-otel-collector.yaml
│   └── aws-cert-manager.yaml
│   └── ...

├── values.yaml

Add-ons

The add-ons directory contains a dedicated Helm chart that deploys each individual add-on.
