POS (Point of sale)

Designed and developed a simple micro-service based POS application using spring boot framework with JPA and Kafka for message queue processing and MySQL for database storage. There are three micro-services - customer, sales and inventory. Customer micro-service is for registering new customer and their total sale. Inventory micro-service is for inventory management of products. Sales micro-service is for processing of order made by the customers. Synchronization between the micro-services are done using Kafka.

  docker compose -f .\pos-docker-compose.yml up

Step 2: go to every module and run -

  docker build . -t customer:v1
  docker build . -t sales:v1
  docker build . -t inventory:v1

Step 3: run the images -

  docker run -p 9081:9081 -e DB_URL='con-db-cust:3306' KAFKA_CONSUMER_SERVER_URL='kafka:9092' customer:v1
  docker run -p 9082:9082 -e DB_URL='con-db-sales:3306' KAFKA_CONSUMER_SERVER_URL='kafka:9092' sales:v1
  docker run -p 9083:9083 -e DB_URL='con-db-inventory:3306' KAFKA_CONSUMER_SERVER_URL='kafka:9092' inventory:v1
