Phonebook Microservice Web Application

The Phonebook Microservice Web Application is designed to provide students with a practical understanding of Microservice architecture by implementing a web application with MySQL Database using Docker and Kubernetes. The project encompasses frontend and backend services interacting with a database service, each managed by Kubernetes deployments. The backend service acts as a gateway, facilitating create, delete, and update operations, while the frontend service enables read operations through a search page. To ensure data persistence, concepts such as persistent volume and persistent volume claim are employed.
