DevOps & Cloud Portfolio Lab

A production-minded DevOps portfolio lab with 54 hands-on projects across Terraform, AWS, Azure, Kubernetes, CI/CD, DevSecOps, monitoring, serverless, and cloud-native application delivery.

This repository is designed to prove practical engineering judgment: infrastructure as code, secure defaults, repeatable validation, cost-aware cloud labs, documented runbooks, and portfolio-ready flagship case studies.

---

Start Here

If you are reviewing this repo for hiring, collaboration, or learning, start with the flagship projects below. They are the highest-signal examples and show the repository's strongest DevOps patterns.

Flagship	What It Demonstrates	Best For
OpenAI Chatbot UI on EKS	AI app containerization, EKS delivery, Terraform, Jenkins, security hardening	DevSecOps + platform delivery
Django SaaS E-Commerce	Multi-tenant Django app, Docker, health checks, secure env handling	Application platform engineering
Terraform AWS EKS	EKS provisioning, Kubernetes app deployment, secrets templating	Infrastructure as code
Cloud Native Monitoring App	Python service, Docker, monitoring workflow, local validation	Observability fundamentals
Online Boutique Microservices	Kubernetes microservices, local cluster manifests, service topology	Microservices operations

Portfolio Story

This repo started as a broad DevOps learning collection and has been hardened into a structured portfolio lab. The latest modernization pass added:

• A machine-readable catalog for all 54 projects through project.yaml files.
• Root-level quality commands through make quality, make list-projects, and make validate-project.
• CI for changed-project validation and local quality gates.
• Updated Docker, GitHub Actions, Kubernetes, and Terraform baselines where safe.
• Security baselines for secrets, Dockerfiles, Terraform, Kubernetes, and CI/CD.
• Flagship runbooks for the strongest showcase projects.

Loading

Quick Start

1. Clone the repo: git clone https://github.com/DevCloudNinjas/DevOps-Projects.git
2. Install the local tooling: python3 -m pip install -r tools/requirements.txt
3. List projects: make list-projects
4. Validate the repo: make quality
5. Open a flagship project and follow its README/runbook

For Students: How to Use Any Project

Each project is meant to be replicated with your own local tools, cloud account, and credentials.

Use this workflow:

1. Read the project README from top to bottom.
2. Check project.yaml for cost risk, deployability, tools, estimated time, prerequisites, learning paths, badges, and validation command.
3. Install only the prerequisites listed for that project.
4. Copy example config files such as .env.example, terraform.tfvars.example, or *.template.yaml.
5. Add your own credentials locally. Never commit real credentials.
6. Run the validation or dry-run command before deploying.
7. Deploy to your own local cluster or cloud account.
8. Observe logs, dashboards, app URLs, or infrastructure outputs.
9. Run cleanup commands and confirm resources are deleted.
10. Write a short learning report about what worked, what failed, and what you fixed.

For the full checklist, see the Student Implementation Guide. For new projects, use the Project README Template.

Use LEARNING_TRACKER.md as a personal template for time planning, prerequisites, validation notes, cleanup, and portfolio evidence.

Learner Metadata Conventions

Projects may include an optional learning section in project.yaml:

learning:
  estimated_time: 4-6 hours
  prerequisites:
    - Docker basics
    - AWS account with budget alert
  learning_paths:
    - containers
    - ci-cd
  badges:
    - local-first
    - portfolio-ready

Learning paths: cloud-foundations, containers, ci-cd, infrastructure-as-code, kubernetes, devsecops, observability, serverless, platform-engineering, security.

Badges: beginner-friendly, local-first, free-tier-aware, cloud-cost-risk, portfolio-ready, team-workflow, security-focused, needs-cloud-account, cleanup-required, capstone.

Local Quality Gate

Run the fast repository checks before opening a pull request:

python3 -m pip install -r tools/requirements.txt
python3 -m pytest tools/tests/test_quality_gate.py -q
python3 -m tools.quality_gate .

The gate is intentionally local and cloud-independent. It checks for tracked files that are now ignored, common secret patterns outside intentional scanner fixtures, plain YAML syntax, shell syntax, Python syntax, and practical Node package lock metadata issues. CI runs the same commands in .github/workflows/local-quality-gate.yml.
