Cloud-I
Idempotent Infrastructure-as-Code (IaC) automation using Ansible to provision cloud virtual machines, configure Docker, and deploy TLS-secured web stacks.
Overview
End-to-end automation provisioning a DigitalOcean VM with Docker Compose and TLS-terminated WordPress.
The Challenge
Deploying infrastructure manually is inherently fragile, unscalable, and undocumented by default. The objective was to eliminate all human intervention by writing an idempotent automation pipeline. The script must be able to securely interact with cloud provider APIs, provision a server, harden the OS, and orchestrate a multi-container application—all from a single terminal command.
The Solution
Ansible roles automating Docker setup, Nginx/WordPress/MariaDB orchestration with persistent storage on DigitalOcean with DNS and TLS.
Architecture & Topology
Technical Deep Dive
Ansible Playbook Orchestration
Authored comprehensive, idempotent Ansible playbooks. The playbooks guarantee a specific end-state regardless of the server's initial condition.
Cloud Provider Integration
Interfaced directly with DigitalOcean's APIs via Ansible to dynamically provision Droplets (VMs), configure SSH key injection, and set up firewall rules.
Container Lifecycle Management
Automated the installation of the Docker engine and Docker Compose, orchestrating an Nginx reverse proxy, MariaDB database, and WordPress application.
Automated Security
Implemented fully automated TLS certificate generation and termination at the Nginx reverse proxy layer, ensuring encrypted web traffic.
