Notification Service is a microservice responsible for consuming and processing Kafka events within the MicroServiceGrid ecosystem.
It listens to the order-placed topic, deserializes events using Avro, and ensures reliable event-driven communication.

• Consume OrderPlacedEvent messages from Kafka
• Deserialize messages using Avro
• Automatically generate Java classes from Avro schemas
• Type-safe deserialization with Spring Kafka
• Integration tests using Testcontainers
• Deployable via docker-compose.override.yml

• Java 21
• Spring Boot 3
• Spring Kafka
• Avro
• Docker Compose
• Testcontainers

git clone https://github.com/Andrij72/notification-service.git
cd notification-service

   ./mvnw clean install

The service runs as part of the shared microservices-net. Docker will automatically pull the image from Docker Hub (andr72/notification-service:latest):

docker-compose -f docker-compose.override.yml up -d

order-placed → Consumes OrderPlacedEvent

Spring Boot Actuator provides a health endpoint:

curl http://localhost:8089/actuator/health

Expected response:

{"status":"UP"}

Part of MicroServiceGrid with API Gateway, Order, Inventory, Product services.
