Kubernetes CI/CD: Build a Pipeline

Build a Complete Kubernetes CI/CD Pipeline with ArgoCD and GitHub Actions

What You'll Learn

  • Build a complete CI/CD pipeline using GitHub Actions and ArgoCD
  • Implement GitOps principles with automated Docker image builds and deployments
  • Configure ArgoCD to monitor repositories and reconcile Kubernetes cluster state
  • Set up automated workflows that trigger on code changes and deploy to Kubernetes
  • Deploy applications to real Kubernetes clusters with zero-downtime deployments

Description

Learn to build a complete Kubernetes CI/CD pipeline using ArgoCD and GitHub Actions in this comprehensive hands-on tutorial. This lesson takes you from setup to a fully functional pipeline that automatically deploys your applications to Kubernetes whenever you make code changes.

You'll start by setting up the foundation with a main application repository and a GitOps repository. The CI part of the pipeline uses GitHub Actions to automatically detect code changes, build new Docker images, and push them to a container registry. The CD part leverages ArgoCD running in your Kubernetes cluster to monitor the GitOps repository for changes and automatically reconcile the desired state with your cluster's current state.

Throughout this tutorial, you'll work with a real application and deploy it to an actual Kubernetes cluster on AWS. You'll configure GitHub Actions to build images automatically, set up ArgoCD to monitor your GitOps repository, and witness the entire pipeline in action as code changes propagate through automated builds, image updates, and Kubernetes deployments.

This hands-on approach ensures you gain practical experience with production-grade CI/CD patterns that follow GitOps principles. By the end, you'll have a professional CI/CD pipeline that automatically deploys your applications whenever you push code changes, demonstrating the power of modern DevOps automation in Kubernetes environments.

The tutorial provides all project files and a preconfigured environment, making it easy to follow along and build your own working pipeline. You'll learn industry best practices for containerization, GitOps workflows, and automated deployment strategies that are essential for modern cloud-native development.
