VPS Setup & Docker

Infrastructure

Private infrastructure

Overview

This project covers the setup and daily management of a Linux VPS hosting multiple client applications via Docker containers. Each application runs in isolation in its own container, with Nginx as a reverse proxy for traffic management and Let's Encrypt for automatic SSL certificates. GitHub Actions handles the CI/CD pipeline for fully automated deployments on every push to the main branch.

Key Features

Docker Compose containerization per client application
Nginx reverse proxy with automatic SSL via Let's Encrypt
Zero-downtime deployments via GitHub Actions CI/CD
Multi-domain hosting on a single server
SSH security with key-based authentication
Centralized logging and monitoring
Automated backups via scheduled scripts

Challenge

Reliably hosting multiple client websites on a single VPS, with zero-downtime deployments, automatic SSL renewal, and easy scalable maintenance - without the cost of managed hosting.

Solution

Docker Compose for containerization and complete isolation per application, Nginx as a reverse proxy with SSL termination via Certbot, and GitHub Actions for automated build-and-deploy pipelines after every commit.
