SecureDeploy is a fully automated, production-ready CI/CD pipeline that builds, scans, and deploys a containerized Python FastAPI application to Azure Kubernetes Service (AKS) — with zero manual steps and zero secrets in code.
This project demonstrates DevSecOps best practices integrated at every stage:
- Shift-left security with 3 automated scanning tools (GitLeaks, SonarCloud, Trivy)
- 100% Infrastructure-as-Code using Terraform
- Automated deployment with GitHub Actions
- Live monitoring with Prometheus + Grafana on Kubernetes
| Skill | What You See |
|---|---|
| CI/CD | End-to-end pipeline: git push → scan → build → deploy 🚀 |
| Cloud | 5 Azure services provisioned and integrated (AKS, ACR, Key Vault, VNet, Storage) ☁️ |
| Security | 3 security gates blocking bad code + running as non-root + secrets in vault 🔐 |
| IaC | 100% Terraform — all infrastructure versioned and repeatable 📋 |
| Kubernetes | Production-ready AKS deployment, rollback, autoscaling, probes 🎯 |
| Observability | Real-time monitoring dashboard with RED metrics 📊 |
Developer Push (git commit)
↓
GitHub Actions CI Pipeline
1. GitLeaks Secret Scan ─→ ❌ Blocks if secrets found
2. Build & Unit Tests ─→ ❌ Blocks if tests fail
3. SonarCloud SAST ─→ ❌ Blocks on quality gate failure
4. Trivy Image Scan ─→ ❌ Blocks on HIGH/CRITICAL CVEs
5. Push to Azure Container Registry
6. GitHub Actions CD Pipeline
↓
Terraform provisions infrastructure
↓
kubectl deploys to AKS
- 2 replicas with liveness/readiness probes
- Auto-scaling based on CPU/memory
- Rolling updates with zero downtime

Prometheus scrapes metrics
Grafana visualizes in real-time dashboard
| Layer | Technology | Purpose |
|---|---|---|
| CI/CD | GitHub Actions | Automated build & deployment pipeline |
| Security | GitLeaks, SonarCloud, Trivy | Secret detection, SAST, container scanning |
| Container Registry | Azure Container Registry | Private Docker image storage |
| Secrets | Azure Key Vault | Secure secrets at runtime |
| Infrastructure | Terraform + Azure | 100% IaC — AKS, VNet, NSG, etc. |
| Orchestration | Kubernetes (AKS) | Container orchestration |
| Monitoring | Prometheus + Grafana | Metrics collection & visualization |
| Application | Python FastAPI | Sample microservice |
✅ Zero Manual Deployments — Git push triggers full automated pipeline
✅ Security Built-In — 3 scanning tools run on every commit
✅ Infrastructure Repeatable — Destroy and recreate with one command
✅ Kubernetes Production-Ready — Health probes, autoscaling, rolling updates
✅ Cost Optimized — Runs on Azure Student free tier
✅ Fully Documented — Every step explained, ready for learning & interviewing

1. Clone & Setup Infrastructure (Day 1)
git clone https://github.com/kovendhan5/securedeploy.git
cd securedeploy
cd terraform
terraform init
terraform apply2. Test App Locally (Day 2)
cd app
pip install -r requirements.txt
pytest tests/ -v
python -m uvicorn main:app --reload3. Configure GitHub Secrets & Deployment (Days 3-7)
# Set these in GitHub repo Settings > Secrets:
ACR_LOGIN_SERVER
ACR_NAME
AKS_RESOURCE_GROUP
AKS_CLUSTER_NAME
AZURE_CREDENTIALS
SONAR_TOKEN
# Then push to main branch — workflow runs automatically!
git push origin main→ Full Setup Guide — Detailed step-by-step for all 7 days
| Stage | Tool | Success Criteria | Fail Action |
|---|---|---|---|
| 1. Secret Scan | GitLeaks | No credentials detected | ❌ Block deployment |
| 2. Build & Tests | pytest + Docker | All tests pass | ❌ Block deployment |
| 3. Code Quality | SonarCloud | Quality gate passes | ❌ Block deployment |
| 4. Image Scan | Trivy | No HIGH/CRITICAL CVEs | ❌ Block deployment |
| 5. Push Image | ACR | Image stored in registry | ⏸️ Stop if failed |
| 6. Deploy to AKS | kubectl | Pods healthy & ready | ⏮️ Rollback if failed |
| 7. Smoke Test | curl | GET /health returns 200 | ⏮️ Rollback if failed |

Security Status: ✅ VERIFIED & APPROVED
Security Score: 95/100
This project implements enterprise-grade DevSecOps practices:
- 🚫 Zero secrets in code — All credentials managed securely
- 🔍 Shift-left security — Scans at every pipeline stage
- 🔒 Container hardened — Non-root, read-only filesystem
- 🛡️ RBAC enforced — Managed identities, principle of least privilege
- ✅ Monitoring active — Real-time alerts and metrics

↓ Secrets ↓ Failures ↓ Issues ↓ CVEs ✓ Clean
BLOCKED BLOCKED BLOCKED BLOCKED Image
- ✅ No
.envfiles in repository - ✅ No hardcoded credentials
- ✅ All secrets retrieved from Azure Key Vault at runtime
- ✅ GitLeaks runs on every commit to catch leaks
- ✅ Runs as non-root user (UID 1000)
- ✅ Read-only root filesystem
- ✅ No privileged capabilities
- ✅ Trivy scans every build for CVEs
Kubernetes Features:
- 2 pod replicas (minimum) for high availability
- Automatic scaling: 2-6 replicas based on CPU (>70%) / Memory (>80%)
- Rolling updates: 0 downtime deployments
- Health probes: Liveness (restart if dead) & Readiness (remove from load balancer)
- Automatic rollback: Previous version restored if new version fails
- Request Rate (req/sec)
- Error Rate (%)
- Response Duration (latency)
- Pod CPU/Memory usage
- Node health status

- Total: < $30/month
- Destroy infrastructure at night:
terraform destroy - Use
Standard_B2s(cheapest VM type) - Monitor costs daily in Azure Portal
- Delete unused images from ACR
