GitOps: ArgoCD Application + Jenkins + Kustomize (dev/prod) + K3d

This repository contains configurations for deploying applications using ArgoCD in a Kubernetes environment.

Repository Structure

• app-ci-image/: Contains Dockerfile and related resources for building the application image.
• k8s-app-kustomize/: Includes Kustomize overlays for different environments (e.g. dev, prod).
• argocd-application-dev.yaml: ArgoCD Application manifest for deploying to the development environment.
• argocd-application-prod.yaml: ArgoCD Application manifest for Production environment.

Prerequisites

• Kubernetes cluster (e.g., k3d)
• ArgoCD installed in the cluster
• kubectl CLI

Getting Started

1. Clone the repository:

   git clone https://github.com/OpsMo/argocd-app.git
   cd argocd-app

2. Set up the application image:

   • Navigate to the app-ci-image directory.
   • Build and push the Docker image manually:

     docker build -t your-repo/your-app:latest .
     docker push your-repo/your-app:latest

   • Or - Alternatively, use Jenkins for CI/CD automation. The Jenkinsfile in the app-ci-image directory provides an Example of pipeline configuration. check the Jenkinsfile.

3. Configure ArgoCD Application:

   • Review and modify argocd-application-dev.yaml as needed.
   • Apply the configuration:

     kubectl apply -f argocd-application-dev.yaml

4. Access the Application:

   • Use ArgoCD's UI or ku to monitor the deployment.

     

   • Once deployed, access the application via exposed service or configured ingress (K3d comes with Traefik controller).
