Flask Docker App

This is a simple Flask web application Dockerized for easy deployment. It provides a starting point for developing and deploying Flask applications using Docker containers.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

• Python 3.x
• Docker

Create a new application from scratch

1. Create a directory with a name "Flask-Docker-App"

  mkdir Flask-Docker-App

2. Navigate to the newly created directory

  cd Flask-Docker-App

3. Create a virtual environment On EC2 Ubuntu

  python3 -m venv venv

4. Activate the environment

  source venv/bin/activate

5. Install Flask

  pip install Flask

6. Create two files

  touch app.py Dockerfile

How to access

  python app.py

This will start the Flask development server. Access the app in your web browser at http://public ip:5000

Deployment with Docker

1. Build the Docker image:

 docker build -t flask-docker-app .

2. Run the Docker container:

 docker run -d -p 5000:5000 flask-docker-app

This will run the Flask app within a Docker container.

3. Access the app in your web browser at http://public ip:5000

Push it to DockerHub

1. Tag the image:

  docker tag <image_name>:latest <username>/<image_name>:latest

2. push the image

  docker push <username>/<image_name>:latest
