product-service project

Simple Java microservice using Quarkus framework

Overview

This service manages a small product domain with following operations:

  • get a product
  • get all product
  • create a product

Product service overview

But it's rather an argument to discover how we can design a Java microservice with Quarkus :)

Technical topics

  • OAuth2 authentication (client credentials flow) with Keycloack
  • JSON request validation with Hibernate validator
  • MongoDB as storage
  • Unit tests and coverage
  • Docker image build
  • Kubernetes template generation

Build

local

./mvnw clean package -Dquarkus.profile=local

java -jar target/quarkus-app/quarkus-run.jar.

docker-compose

build image for JVM

./mvnw clean package -Dquarkus.container-image.build=true -Dquarkus.container-image.image=my-registry.com/jami/quarkus/product-service -Dquarkus.profile=docker

build native image

It will download Quarkus Mandrel image builder (about 700mb)

./mvnw clean package -Pnative -Dquarkus.native.container-build=true -Dquarkus.native.builder-image=quay.io/quarkus/ubi-quarkus-mandrel:21.0.0.0-Final-java11 -Dquarkus.container-image.build=true -Dquarkus.container-image.image=my-registry.com/jami/quarkus/product-service -Dquarkus.profile=docker

Run It will download MongoDB and Keycloak images (about 1.1Gb)

docker-compose up -d
