This is Part 1 of a series where I build a complete DevOps pipeline from the ground up; local deployment, CI/CD, security scanning, monitoring, and alerting. Series Overview This series documents the end-to-end process of building a production-grade DevOps pipeline. Here's where we're headed: Part 1: Local Deployment with Vagrant, Docker, and Nginx Part 2: CI/CD Pipeline with GitHub Actions (automated testing and deployment on every push) Part 3: Security Scanning with Trivy (container image and code vulnerability scanning) Part 4: Monitoring and Logging Part 5: Slack Alerting for Failed Builds and Deployments (real-time notifications when things go wrong) Resources The Vagrantfile, Nginx config, and Docker Compose files used in this guide are available here: devops-pipeline-series The application code is sourced from Docker's official Repo What We're Building in Part 1 In this first part, we deploy a full-stack web application locally using Vagrant as the infrastructure layer, Docker
