☁From Code to Cloud: A Step-by-Step Guide to Building and Deploying Python Flask Applications 👨🏽‍💻

☁ Cloud-Based Development: A Beginner's Guide to Building Python Flask Applications with Deployment.☁

Getting Started 👨🏽‍💻

To begin, ensure you have a Linux environment set up. If you're using Windows 10, install Windows Subsystem for Linux (WSL) and configure an instance, as outlined in my previous article.

File Extensions Overview

Familiarize yourself with common file extensions:

🔵 Python: .py
🔵 JavaScript: .js
🔵 C#: .cs
🔵 Ruby: .rb
🔵 PHP: .php

Our Focus

In this tutorial, we'll concentrate on building and deploying Python application, utilizing .py

Deployment Guide: Python Application.

Section A

Create an Instance

Follow the detailed instructions in my previous article to create an instance on AWS EC2: Post

Refer to Section A for the step-by-step guide 🤓.

Section B

Connect to Your Server 🤭

Once your instance is set up, connect to your server by following Section B in the same article: Post

For the pictorial deployment guide of Python application.

Section C

Deployment Phase

Step: Update Virtual Server😌😊.

Step 2: Verify Python Installation - Check Version.

Step 3: Create 'apps' Directory and Verify.

Step 4: Access 'apps' Folder, Create a New File and Open for Editing.

Step 5: Add Your Code to the Newly Created File

Step 6: Save & Exit Nano Editor (Ctrl x, Y, Enter)

Step 7: Review File Contents.

Step 8: Execute Python Code.

Step 9: Set Up Virtual Environment.
(1. You can see it’s not install) (2. You can see it is not install) (3. Install virtual environment {venv})

Check if Virtual Environment is Installed.

python3 -m venv

If not installed:

sudo apt-get install python3-venv

Step 10: Run and Activate venv

To activate:

Source Jamiu/bin/activate

Step 11: Install Flask framework Using pip.

pip install flask

Step 12: List packages installed in the virtual environment.

Step 13: Create app.py and Open in Nano Editor.

Insert this code:

from flask import Flask

app = Flask(__name__)

@app.route("/")
def hello_world():
    return "<p>Hello, This is my first Live Python Flask app!</p>"

Step 14: Execute app.py with Python and Start Flask Server.

Flask app is running, but only accessible internally.

Step 15: Go Live - Make Application Accessible to External Users.

Step 16: Verify Application Status - Running and Active.

Congratulations! 🎉 You've Successfully Deployed Your First Flask Application in Python. 🕺🏽🕺🏽🕺🏽
