Acme Air MicroServices with Quarkus

This is a Quarkus implementation of Acme Air, a sample microservice application that emulates an air ticketing system. This is ported from its SpringBoot implementation. The components and their connections are depicted here.

Quarkus is a cloud native Java framework based on modern standard APIs. More information about its fancy features are available at https://quarkus.io/.

This repository includes all five services of Acme Air, though the original five repositories are separated in the BLUEPERF GitHub organization.

This repository also includes configuration files to run the application and its load generator in containers on a local machine or OpneShift cloud environment.

Build Instructions

Clone git repo

git clone https://github.com/IBM/acmeair-quarkus.git

Building the application

cd acmeair-quarkus
mvn package

This step builds all five services, and creates docker images of the services and other services like mongodb. It also creates a docker image of the driver, a load generator by using Apache JMeter scenario. The scenario and its JMeter plugin are found in acmeair-driver repository in BLUEPERF.

Creating a native executable if interested

One of a major feature of Quarkus is native binary support. You can build the five microservices as native binaries by adding -Pnative in the Maven command line:

mvn package -Pnative

You can distinguish whether an image is Java version or native version by checking its image tag. For example, acmeair-mainservice-quarkus:jvm is a Java version, and acmeair-mainservice-quarkus:native is a native version.

Usage Instructions

Setting up docker network

Make sure you correctly installed docker engine and docker-compose, and start docker daemon on your machine. The instruction is available here.

Then, create docker network for connecting the microservices and other components:

docker network create --driver bridge my-net

You can pick any name for the network. my-net is just an example.

Starting the application

Use docker-compose to start containers of all five microservices, three mongodb instances, and an nginx proxy:

NETWORK=my-net docker-compose -f acmeair-mainservice-quarkus/docker-compose.yml up

Verifying the application manually

1. Access http://localhost/acmeair with your browser.
2. Click a link at the bottom of the page and go to the Acme Air Configuration information page.
3. Press the Load the database button in the Actions: bar to load the database for three services.

The application is ready if no error is reported.

Measuring performance using the driver

The instruction to use driver is described in driver/Readme.md.
