Services

• Eureka Server (8761): Service discovery
• API Gateway (8080): Single entry point for all microservices
• Event Service (8081): Manages events and ticketing
• User Service (8082): User authentication and management

Getting Started

Prerequisites

• Java 21
• Maven 3.8+
• Docker & Docker Compose

Building the Project

# Build all modules
mvn clean package

# Build with Docker
docker-compose build

Running Locally

# Start all services
docker-compose up

# Or run individual services
mvn spring-boot:run -pl services/eureka-server
mvn spring-boot:run -pl services/api-gateway
mvn spring-boot:run -pl services/event-service
mvn spring-boot:run -pl services/user-service

Accessing Services

• Eureka Dashboard: http://localhost:8761
• API Gateway: http://localhost:8080
• Event Service: http://localhost:8081
• User Service: http://localhost:8082
• Prometheus: http://localhost:9090
• Grafana: http://localhost:3000 (admin/admin)

API Endpoints (via Gateway)

• Events: http://localhost:8080/api/events
• Users: http://localhost:8080/api/users

Development

Each service can be developed independently. The common module contains shared models and utilities.

Adding a New Service

1. Create a new module under services/
2. Add the module to the parent POM
3. Configure the service with Eureka client
4. Add routing rules in the API Gateway
5. Update docker-compose.yml

Monitoring

• Actuator endpoints exposed for health checks
• Prometheus metrics available at /actuator/prometheus
• Grafana dashboards for visualization# tickon-api
