Lightweight Alpine-Based CI/CD Pipeline

A reusable Alpine-only CI/CD pipeline that builds multi-arch Docker images, runs linting, testing, vulnerability scanning and SBOM generation without Docker-in-Docker. Serves as foundation for all future sprints.

🎯 Project Goals

• Multi-architecture Docker builds (amd64, arm64, arm/v7)
• Security-first approach with vulnerability scanning and SBOM generation
• Alpine Linux base for minimal attack surface and fast builds
• No Docker-in-Docker for better security and performance
• Reusable foundation for all future CI/CD needs

🚀 Quick Start

Prerequisites

• Docker & Docker Compose
• Access to container registry (GHCR, Docker Hub, etc.)

Environment Setup

# Copy environment template
cp .env.example .env

# Edit with your registry details
REGISTRY=ghcr.io/your-org
IMAGE=your-app
TAG=latest

Run Full Pipeline

# Run complete CI pipeline
make ci

# Or run individual stages
docker compose -f ci/docker-compose.yml up lint
docker compose -f ci/docker-compose.yml up test
docker compose -f ci/docker-compose.yml up build
docker compose -f ci/docker-compose.yml up scan

📋 Sprint Overview

Sprint 0: Setup & Validation (2 days)

• CI skeleton creation
• Basic Dockerfiles and orchestration
• Environment validation

Sprint 1: Core Pipeline Integration (5 days)

• Multi-arch build & push
• Security scanning & SBOM
• Developer experience improvements

Sprint 2: Quality Gates & Documentation (4 days)

• Code quality enforcement
• Test coverage reporting
• Compliance documentation

🔧 Development Workflow

1. Feature Development: Create feature branch
2. Local Testing: Run make ci locally
3. Pipeline Execution: Push to trigger full CI/CD
4. Quality Gates: Automated checks and approvals
5. Deployment: Multi-arch images pushed to registry

📊 Success Metrics

• Build Time: < 10 minutes for full pipeline
• Security: Zero high-severity CVEs
• Coverage: > 80% test coverage
• Compliance: NIST 800-53 controls mapped
• Reusability: Foundation for 5+ future projects
