Plantation project

I created this project to try-out knowledge obtained during the Udemy course about Spring Cloud.

The system itself is represented by 3 domain microservices and 2 spring-cloud-specific microservices. es. Besides that, domain services requires PostgreSQL, MongoDB for the persistence layer, and RabbitMQ for async communication.

There is a helm chart for the system to run it within k8s, even though k8s provide capabilities to substitute some of Spring Cloud solutions, I wanted to combine those 2 approach

Theme of the services is tea distribution

• Plantation service - creates and manages information about Tea, periodically makes a sync-up with Inventory service for tea warehousing
• Inventory service - service for Tea warehousing holds information about available tea amount for selling
• Order service - service that holds tea ordering logic, works as coordinator during order processing between Plantation service and Inventory service

How to build

The codebase is organized as a Gradle multi-module project, each microservice registered as an "included build" which means each microservice is an independent build unit

Build

• ./gradlew tea-plantation:build
• ./gradlew tea-inventory:build
• ./gradlew tea-order:build
• ./gradlew discovery:build
• ./gradlew gateway:build

Build docker images

• ./gradlew tea-plantation:dockerBuild
• ./gradlew tea-inventory:dockerBuild
• ./gradlew tea-order:dockerBuild
• ./gradlew discovery:dockerBuild
• ./gradlew gateway:dockerBuild

How to make a helm chart

1. cd ./helm/tea-plantation
2. helm dependencies update
3. helm upgrade --install plantation -n plantation .

After installation Open-api will be available at http://${NODE_ADDRESS}/swagger-ui.html

NOTE

For helm chart you should provide host and port values for MongoDB, PostgreSQL and RabbitMQ

• global.postgres.host
• global.postgres.port
• global.rabbitmq.host
• global.rabbitmq.port
• global.mongodb.host
• global.mongodb.port
