Creating a Developer Portfolio with Flask and Docker

technical SOP

Created: May 21, 2025

Introduction

This document outlines the process of creating and deploying a developer portfolio web application using Flask, SQLite, Docker, Docker Compose, and Docker Swarm. The application is designed to be deployed on a virtual private server (VPS) with zero downtime updates.

Executive Summary

Core Insights

Flask and SQLite are used to build the web application.
Docker and Docker Compose are utilized for containerization and orchestration.
Docker Swarm mode is used for deploying the application on a VPS.
Zero downtime updates are achieved by separating the web app and database services.

Expected Outcomes

A fully functional developer portfolio website.
Deployment on a VPS with zero downtime updates.
Improved security through SSH key management.
Scalable architecture using Docker Swarm.

Critical Considerations

Ensure compatibility between Flask version and Gunicorn server.
Properly configure Docker Compose file for service definitions.
Secure SSH access with strong passwords and keys.
Monitor server performance and resource usage.

Strategic Recommendations

Use Flask for backend development.
Utilize Docker for consistent development and production environments.
Implement Docker Swarm for scalable deployment.
Ensure proper configuration of SSH keys for secure server access.
