When I first started writing code, my ultimate goal was simple:
Make it work.
But as my applications grew, a new set of questions kept me up at night:
- How do I ensure this app runs identically on a server as it does on my laptop?
- How do I securely scale infrastructure when traffic spikes?
- How do I automate the delivery pipeline so deployment becomes a non-event?
Driven by this curiosity, I decided to transition from just writing code to understanding the entire lifecycle of software delivery. I didn't want to just watch tutorials—I wanted to get my hands dirty.
Today, I’m excited to share the culmination of that effort: my DevOps Practice Repository! 🛠️
📂 What’s Inside the Repository?
I structured this repo into progressive, isolated modules to document my hands-on learning across major cloud and automation technologies:
🐳 Docker (17 Tasks): Advanced containerization patterns, multi-stage production builds (Vite/React/Nginx), resource limits, health checks, and Docker Swarm.
🏗️ Terraform (GCP & DigitalOcean): A 14-level progressive track on Google Cloud covering Custom VPCs, Cloud NAT, private Cloud SQL, module composition, and Workload Identity Federation (OIDC) for secretless authentication.
☸️ Kubernetes (12 Tasks): Managing self-healing Deployments, Ingress routing, persistent storage (PVCs), and microservice orchestration.
🔁 Nginx (11 Tasks): Building high-performance configurations for reverse proxying, load balancing, rate limiting, and security hardening.
🌿 Git Mastery (~40+ Scenarios): Deep dive into advanced workflows including interactive rebasing, bisect, reflog, and complex conflict resolution.
The Capstone: To tie it all together, I built the Totes App—a full-stack FastAPI + React application, containerized via Docker Compose, and deployed automatically through a GitHub Actions CI/CD pipeline to Azure App Service.
💡 My Biggest Takeaway
DevOps isn't just a collection of tools; it’s a mindset centered around automation, reliability, and security. Building this repository taught me how to bridge the gap between development and operations to build genuinely resilient systems.
Whether you're a fellow engineer looking for configuration references, a mentor, or a recruiter, I’d love for you to check out the codebase! (It is fully open-source under the MIT License).
