Spring Boot Microservices Project

Overview

This project is a microservices-based application built using the Spring Boot framework. The application leverages several key technologies to provide a scalable and reliable system:

• MySQL for data persistence
• Cassandra for distributed NoSQL data storage
• RabbitMQ for message streaming between services
• Redis for caching and session management

The project is containerized using Docker and deployed to a Kubernetes cluster for orchestration.

Prerequisites

• Java 11 or higher
• Gradle
• Docker
• Kubernetes cluster (Minikube, EKS, GKE, etc.)
• kubectl configured for your Kubernetes cluster

Project Structure

• src/main/java: Contains the main Java code for the Spring Boot application.
• src/main/resources: Contains the application properties and configuration files.
• Dockerfile: Instructions for building the Docker image.
• kubernetes/: Contains Kubernetes manifests for deploying the services.

Building the Project

1. Clone the Repository:

   git clone https://github.com/A-LPHARM/sprigbootprojects.git
   cd chat-messaging-app

2. Build the Project: Use the Gradle wrapper to build the project:

   ./gradlew build

3. Build the Docker Image: After successfully building the project, create a Docker image:

   docker build -t henriksin1/chatapp:latest .

4. Push the Docker Image: Push the image to your Docker registry:

   docker push henriskin1/chatapp:latest

Deploying to Kubernetes

1. Create Kubernetes Secrets: Create secrets for MySQL, Cassandra, RabbitMQ, and Redis.

2. Apply Kubernetes Manifests: Deploy the application and its dependencies to your Kubernetes cluster:

   kubectl apply -f manifests/

3. Verify Deployment: Ensure all pods are running and services are available:

   kubectl get pods -n messaging-app
   kubectl get svc -n messaging-app

4. Access the Application: Use the Kubernetes service endpoint to access the application.

Configuration

The application can be configured using environment variables or by editing the application.properties file in the src/main/resources/ directory.

Monitoring and Logging

• Ensure to monitor your services using Kubernetes dashboard or other monitoring tools like Prometheus and Grafana.
• Logs can be viewed using kubectl logs command.
