Quickstart: Deploy a Flask App

This guide will walk you through deploying a production-ready Flask application on Seenode. We’ll use Gunicorn as our production WSGI server.

Get started in seconds by deploying a pre-built Flask template.

Flask Template

Deploy a minimal, production-ready Flask application with Gunicorn.

Deploying an Existing Flask Project

Follow these steps to deploy your existing Flask application from a Git repository.

Prepare Your Flask App

Ensure your project is configured for production.

Project Structure

Your project should have an app.py file and a requirements.txt.
- Directorymy-flask-app/
  - app.py
  - requirements.txt
Example app.py

Seenode will look for an app instance in your app.py file.
app.py
```
from flask import Flask

app = Flask(__name__)

@app.route("/")
def hello_world():
    return "Hello, from Seenode!"
```
requirements.txt

Your requirements.txt should include flask. For production, we also recommend a WSGI server like gunicorn.
requirements.txt
```
flask
gunicorn
```
Deploy on Seenode

Follow these steps to deploy your Flask application:
1. From the Seenode Dashboard, create a New Web Service, connect your Git provider, and select your Flask project’s repository.
2. Configure your service’s settings. For a typical Flask app, you can use the following:
  - Build Command: pip install -r requirements.txt
  - Start Command: gunicorn app:app --bind 0.0.0.0:8000
3. Choose your preferred instance size and create the service.
4. Watch your deployment progress in real-time in the Logs tab.
5. Once complete, your application will be accessible via your service’s URL.

Now that your Flask app is deployed, here are some recommended next steps:
