Last week, I was exploring the options to deploy the FastAPI project on the VPS, and I found that it’s super easy to deploy the FastAPI app.

I will share a quick step-by-step guide that will cover the following :

  • A domain configured with Nginx reverse proxy
  • FastAPI app inside a virtual environment
  • And also a background service that will ensure the app is always running even after a reboot.

Let’s start with Nginx. We will create a site-available config file for our app domain.

sudo nano /etc/nginx/sites-available/
server {
listen 80;

location / {
proxy_pass; # should match with the fastapi port
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

To enable the domain/site, we need to create a symbolic link to the site-available config file in the site-enabled directory of Nginx.

sudo ln -s /etc/nginx/sites-available/ /etc/nginx/sites-enabled/
