GitOps Handbook

Have you ever deployed an app to Kubernetes and later realized you don't really know what changed, who changed it, or how to roll it back safely? Maybe dev looked fine, staging looked stable, and production still broke at midnight, right when nobody wanted to touch it.

This is exactly the problem GitOps exists to solve.

GitOps isn't just another DevOps trend. It's a deployment model where Git becomes the single source of truth for your infrastructure and applications. Your cluster continuously pulls the desired state from Git, so every change is auditable, reversible, and predictable.

Tools like ArgoCD make this possible on Kubernetes, and that's exactly what this course teaches you, starting from the core concepts and working all the way to real production deployments.

What you'll learn

This course is split into four modules, taking you from concepts to implementation to production-grade, safe deployments.

Module 1: GitOps Foundations

• What GitOps really is, and how it compares to traditional DevOps
• Why GitOps is not just CI/CD, and why it's trending right now
• Push vs pull deployments, explained with real-world examples

Module 2: Getting Started with ArgoCD

• Installing ArgoCD and understanding its architecture
• Deploying your first application the GitOps way
• Setting up RBAC and managing user access

Module 3: Working with ArgoCD

• Secret management in GitOps
• Helm vs Kustomize deployments
• Multi-environment GitOps strategy across dev, staging, and production

Module 4: Progressive Delivery with Argo Rollouts

• Blue-green and canary deployments
• Automated rollbacks
• Metrics based decision and safe production releases

Who this course is for

This course is for you if you deploy applications to Kubernetes and want a safer, more predictable way to do it. It works well whether you're a DevOps engineer tired of manual deployments, a platform engineer building GitOps workflows for your team, or a developer and student who just wants to understand what ArgoCD and Argo Rollouts are actually doing under the hood.

You don't need any prior experience with ArgoCD to start. A basic understanding of Kubernetes will help you get more out of the course, but the first module builds up the concepts from scratch anyway.

Start the course

Start with Module 1 and go through the four modules in order. Each one builds on the last, so you move from GitOps concepts, to your first ArgoCD deployment, to running progressive, production-grade rollouts by the end.

By the time you finish the final project in Module 5, you'll have hands-on experience with the same GitOps setup used to run real production systems.
