Project Modules
Follow these build guides in order. Published modules are ready to start.
Before You Start
- Before starting this project, readers should ideally possess the following technical background and system setup:
- Programming Core: Foundational knowledge of Python 3.11+ and micro web frameworks, specifically Flask.
- Containerization: Basic understanding of Docker concepts, writing Dockerfiles, and orchestrating multi-container environments with Docker Compose.
- Version Control: Familiarity with Git, standard branching strategies (Git Flow: Main, Develop, Feature branches), and GitHub repositories.
- Cloud & DevOps Basics: Basic understanding of Linux command-line operations, Cloud Infrastructure concepts (GCP/AWS), and Infrastructure as Code (IaC) principles.
- Local Machine Requirements: Minimum 8GB RAM (16GB recommended) with Docker Desktop, Google Cloud SDK, Terraform, kubectl, and Helm pre-installed.
What You'll Learn
- ✓By completing this end-to-end DevOps project, readers will gain hands-on production experience in the following domains:
- ✓Production-Grade App Architecture: Learn how to engineer a production-ready Flask application powered by Gunicorn, featuring robust configuration management, structured logging, and Kubernetes-native liveness/readiness probes.
- ✓Advanced Container Optimization: Implement secure multi-stage Docker builds that significantly reduce final image sizes and minimize the attack surface by isolating runtime binaries from build tools.
- ✓Automated CI/CD Pipelines: Build enterprise-grade GitHub Actions workflows that automate code compilation, linting (flake8), security analysis (CodeQL/Trivy), and continuous deployment directly to cloud clusters.
- ✓Infrastructure Automation (IaC): Provision and manage a fully functioning Google Kubernetes Engine (GKE) cluster programmatically on GCP using declarative Terraform blueprints.
- ✓Kubernetes Orchestration: Master environment-specific deployments (Dev, Staging, Prod) using standard cloud tools like Helm charts and Kustomize overlays.
- ✓Enterprise Observability: Wire up comprehensive metric scraping, log aggregation, and real-time dashboard visualizations using Prometheus, Grafana, and AlertManager to achieve operational awareness.
