Deploying a Docker Compose Stack to a Vultr VPS with Nginx and HTTPS

So you’ve built an awesome web project with Flask (your “web” frontend), a FastAPI backend (your “api”), a Redis database, and even a Celery worker, all neatly orchestrated with Docker Compose. That’s fantastic! Now, the exciting part: taking it live for the world to see.

While managed services like Google Cloud Run offer simplicity, sometimes you need more control, a predictable monthly cost for consistent usage, or simply enjoy getting your hands dirty with server administration. That’s where a Virtual Private Server (VPS) like comes in.

A VPS deployment is a single-host production setup where you own the whole stack — operating system, container runtime, reverse proxy, and TLS certificates — in exchange for a fixed monthly price rather than per-request billing. This post walks you step by step through deploying a Docker Compose project to a Vultr VPS, with Nginx as the reverse proxy and HTTPS via Certbot and Let’s Encrypt.

Prerequisites

1. A Vultr Account: If you don’t have one, sign up at .
2. A Domain Name: Registered with a provider like GoDaddy.
3. SSH Client: For Windows, PuTTY or Git Bash; for macOS/Linux, your built-in terminal.
4. Git: Installed on your local machine to manage your code.
5. Your Project on GitHub (or similar): Your application code should be in a Git repository accessible from your server.
