How To Deploy a Flask Application on an Ubuntu VPS

If you have built a web application using Flask, you may want to deploy it on a server so that others can access it. In this tutorial, we will show you how to deploy a Flask application on an Ubuntu Virtual Private Server (VPS).

Step 1: Set Up Your VPS

First, you need to set up an Ubuntu VPS. You can use a service like DigitalOcean, Linode, or AWS to create a new VPS instance. Follow the provider's instructions to create a new VPS instance and SSH into it.

Step 2: Install Required Packages

Once you have SSH access to your VPS, you need to install the required packages for your Flask application to run. Install Python, pip, and virtualenv:

sudo apt-get update
sudo apt-get install python3-pip python3-dev build-essential libssl-dev libffi-dev python3-setuptools
sudo apt-get install python3-venv

Step 3: Create a Virtual Environment

Create a virtual environment for your Flask application:

python3 -m venv myprojectenv
source myprojectenv/bin/activate

Step 4: Install Flask and Other Required Packages

Install Flask and any other required packages:

pip install flask
pip install gunicorn
pip install -r requirements.txt

Step 5: Configure Your Flask Application

Edit your Flask application's configuration file to run in production mode:

app = Flask(__name__)
app.config.from_object('config.ProdConfig')

Step 6: Run Your Flask Application

Start your Flask application with Gunicorn:

gunicorn --bind 0.0.0.0:8000 wsgi:app

Step 7: Configure Your Firewall

Configure your firewall to allow incoming connections on port 8000:

sudo ufw allow 8000/tcp

Congratulations! Your Flask application is now running on your Ubuntu VPS.
