# My Web Application

## Project Description

This project is a simple web application that provides a user interface to manage a MySQL database. The application consists of a single page that allows the user to perform basic CRUD operations on a list of items stored in the database.
Containers

## The application consists of the following containers:

    mysql: This container runs the MySQL database server.
    web: This container runs the web server and serves the web pages to the user.


## The following Kubernetes objects are used in the application:

    PersistentVolume: This object is used to create a named volume for the MySQL data.
    StatefulSet: This object is used to manage the mysql container and ensure that there is only one instance running at any given time.
    Deployment: This object is used to manage the web container and ensure that there is always at least one instance running.
    Service: This object is used to provide access to the mysql and web containers from outside the Kubernetes cluster.

## Virtual Networks and Named Volumes

The application uses a virtual network to allow communication between the mysql and web containers. The mysql container stores its data in a named volume called mysql-persistent-storage.

## Container Configuration

The mysql container is configured to use the mysql-persistent-storage volume for data storage. The web container is configured to connect to the mysql container using the Kubernetes service mysql.

## To run the application, perform the following steps:

    1. Install Kubernetes on your machine.
    2. Install azure-cli: curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash
    3. Clone the project repository.
    4. Change into the project directory.
    4. Login in Azure: az login 
    4. Execute "./prepare-app.sh" make sure it have execution permission.
    5. Wait for the mysql and web containers to start.

## To view the application on the web, perform the following steps:

    Get the IP address whit this command: kubectl get service phpmyadmin -n ibanweb -o jsonpath='{.status.loadBalancer.ingress[0].ip}'
    In your web browser, navigate to http://<web-service-ip>.


## To clean up the application, perform the following steps:

    Execute "./remove-app.sh" make sure it have execution permission.
