Deploy a Flask app on Enzonic

At a glance

What Enzonic Deploy does with a Flask project when you connect it. You can override any of it in the project settings.

How it runs

Deploy Flask step by step

from flask import Flask, jsonify

app = Flask(__name__)

@app.get('/')
def index():
    return jsonify(hello='world')

Connect a database to Flask

Create a database on Enzonic Databases (or from the project's settings) and its connection string is added to the project's environment variables. This example uses MySQL.

import os
from sqlalchemy import create_engine, text

# MySQL or MariaDB on Enzonic: TLS is required, so pass ssl.
url = os.environ['DATABASE_URL'].replace('mysql://', 'mysql+pymysql://', 1)
engine = create_engine(url, connect_args={'ssl': {}}, pool_pre_ping=True)

@app.get('/count')
def count():
    with engine.connect() as conn:
        return {'posts': conn.execute(text('select count(*) from posts')).scalar()}
