🐳 ToDo App 📝

This repository (accessible at ThreeLittleBirdsContainerized/todo-app) contains a project realized as part of the Software Containerization course of the Master's degree in Artificial Intelligence, Vrije Universiteit Amsterdam.

ToDo App is a website allowing simple Create, Read, Update, Delete operations to manage tasks. It is composed of:

• frontend built in Angular, reading data from the API
• API built in Python with Flask
• MySQL database, implemented on MariaDB

This project coded from scratch and google cloud was used to deploy the project.

These components are deployed in containers using Kubernetes Engine on Google Cloud.

A demo of the application is available at the following link: https://todo.group3.site
