docker-compose up -d

At this point everything should be up and running! You can access to UI at

Additionally, you may take a look at Microservices gRPC UI for UI code.

Local Development

For running services in local environment you will need a MongoDB & PostgreSQL instance, you can use local.yml It will set up MongoDB, PostgreSQL and UI.

docker network create uid4oe
docker compose --file local.yml up -d

Do not forget to add below VM argument to every service.

-Dspring.profiles.active=develop

Also, for each service add grpc-java & java folders as Sources in File->Project Structure. This will allow IDE to see the generated gRPC classes.

You can start using the app through UI at

http://localhost:3000/java
