Start Infrastructure
The “infrastructure stack” is composed of the following components:
- One PostgreSQL instance per micro service
- One Kafka broker
- One Service Discovery microservice to enable load balancing & loose coupling.
- One Configuration server is also used to centralise the configuration of our microservices.
- The following microservices: API Gateway, Merchant BO, Fraud Detect, Smart Bank Gateway
🛠️ Execute the following commands
./gradlew build --parallel -x testdocker compose up -d --build --remove-orphans✅ To check if all the services are up, you can run this command:
$ docker compose ps -aAnd check the status of every service.
For instance:
❯ docker compose ps

Gradle build error
You may encounter Gradle build errors due to a timeout when trying to get the lock on some files (as all the services are built concurrently). You can either:
- Execute the
docker compose up -d --buildcommand each time you have the error until the environment is started, - Or disable concurrency by executing the two following commands:
./scripts/build-services.sh(takes a long time as all services are built one by one),docker compose up -d --build(should work this time as all services are built by the previous command).
