Argo CD GitOps Deployment Guide
Argo CD is a GitOps tool for automating Kubernetes cluster synchronization with a Git repository. This guide helps you set up Argo CD using a custom Helm chart.
Requirements:
Kubernetes cluster (v1.28+) kubectl (v1.28+) Helm (v3.13+) Public Git repository for Argo CD manifests Getting Started:
Create Custom Helm Chart:
Make a directory for the Helm "umbrella chart" (e.g., charts/argo-cd). Add a Chart.yaml file with dependencies on the Argo CD Helm chart. Create a values.yaml file to configure Argo CD settings. Generate Helm Chart Lock File:
Use Helm commands to add the Argo CD repository and update dependencies. Ignore the generated lock file (charts/argo-cd/Chart.lock) in version control. Push to Git Repository:
Add and commit the custom chart to your public Git repository. Install Argo CD:
Install Argo CD using the Helm chart. Access Argo CD UI:
Retrieve the NodePort service details (kubectl get services -n argocd argocd-service). Access the Argo CD UI in your browser using the provided NodePort. Usage:
Define workloads declaratively in YAML files and commit changes to the Git repository. Argo CD automatically synchronizes the cluster based on Git repository changes. Note:
Configuration is minimal in this guide, disabling unnecessary components. Ensure security measures for production deployments.
