In this session, I will walk you through how we traditionally deploy applications to Kubernetes — usually by manually writing YAML files and using kubectl apply to push changes.

While this works at small scale, it quickly becomes error-prone and hard to manage as teams grow.

I’ll introduce the concept of GitOps, where Git becomes the single source of truth for both code and infrastructure.

We’ll talk about the problems GitOps solves: better visibility, easier rollbacks, and safer deployments.

Then, we'll focus on Argo CD, a popular GitOps tool for Kubernetes.

I'll show how to install it, set up a simple application (like the guestbook app), and automate deployments directly from Git — with no manual kubectl commands.
