GitOps Journey: Part 1 – Getting Started with ArgoCD and GitHub (opens in new tab)

Welcome to GitOps Journey — a hands-on guide to setting up infrastructure in Kubernetes using Git and automation. GitOps has gained traction alongside Kubernetes, CI/CD, and declarative provisioning. You’ve probably seen it mentioned in blog posts, tech talks, or conference slides — but what does it actually look like in practice? We’ll start from scratch: prepare a cluster, deploy a PostgreSQL database, run a demo app, and set up observability — all managed via Git and GitHub using ArgoCD.
