This is a Python CRUD project using Flask, Docker and PostgreSQL. It includes a Dockerfile, Python source code, and SQLAlchemy for easy database configuration. CRUD capabilities enable create, read, update, and delete operations. Code is structured in a modular, clean way for easy maintenance.

This application uses the Model-View-Controller (MVC) pattern to separate the different parts of the application into three distinct components. I believe that this approach can make my code more modular, easier to maintain and update, and facilitate collaboration among us developers. In brief, the use of the MVC pattern makes my application more robust, scalable, and easy to maintain.

1. Clone the repository:

   git clone https://github.com/username/repo.git
   

2. To run the Postgres container, type:

   docker compose up -d flask_db
   

3. Go back to the folder where the docker-compose.yml is located and type:

   docker compose build
   
   

4. Run the flask_app service:

  docker compose up flask_app

5. Access the app in your browser at http://localhost:5000/.

This app enables the following CRUD operations:

• Create: Adds a new entry to the database.
• Read: Retrieves data from the database.
• Update: Modifies an existing entry in the database.
• Delete: Removes an entry from the database.
