The Simplest End-to-End DevOps Project | Hello World to Production
🚀 From “Hello World” to Production: Simplest DevOps Flow for Beginners!
Are you new to DevOps and struggling to understand how all the tools and stages connect? This hands-on tutorial walks you through a complete, beginner-friendly DevOps pipeline using the simplest possible "Hello World" Python Flask app.
No overwhelming complexity — just the essentials to help you see the big picture!
🎁One git push in the application code-
✅triggers GitHub Actions ci that-
➡️creates docker image and pushes to DockerHub,
➡️it also changes our kubernetes manifest
✅which is picked up by ArgoCD and we see the changes in EKS.
✅which is created using IaC tool Terraform
✅Moreover, Prometheus is there always to pick up all the metrics and Grafana to beautifully present that in a dashboard.
In this video, we'll cover:
Building a minimal Python + Flask app
Version Control with Git & GitHub
Containerization with Docker
Pushing image to DockerHub
Continuous Integration (CI) using GitHub Actions
Running on Kubernetes cluster on AWS
Infrastructure as Code (IaC) with Terraform
Continuous Deployment (CD) with ArgoCD (GitOps style)
Observability with Prometheus & Grafana
Perfect for absolute beginners who want to go from local code to a fully deployed, observable app in production!
