Docker setup help, Failed to obtain JDBC Connection

[yevon]

I've reached this amazing project and I want to give it a try, but I'm unable to setup the enviroment with docker. I've tried two tutorials without success. If I follow the docker instructions at the end of this repository, I just end up with this message if I perform a get request to the /jobs url:

The same if I make a POST request with postman, same message:

My docker-compose config looks like this:

rabbit:
  image: creactiviti/rabbitmq:3.7.7-management
  hostname: rabbit
  ports:
    - 15672:15672
    - 5672:5672
  restart: always

postgres:
  image: postgres:11
  ports: 
    - 5432:5432
  environment:
    - POSTGRES_DB=piper
    - POSTGRES_USER=piper
    - POSTGRES_PASSWORD=piper

coordinator:
  image: creactiviti/piper:latest
  ports:
    - 8080:8080
  environment:
    - piper.worker.enabled=true
    - piper.coordinator.enabled=true
    - piper.worker.subscriptions.tasks=1
    - piper.pipeline-repository.filesystem.enabled=true
    - piper.pipeline-repository.filesystem.location-pattern=/app/pipelines/**/*.yaml
    - spring.datasource.initialize=true
    - spring.datasource.name=piper
    - spring.datasource.platform=postgres
    - spring.datasource.url=jdbc:postgresql://localhost:5432/piper
    - spring.datasource.username=piper
    - spring.datasource.password=piper
  volumes:
    - D:/test/docker/piper/pipelines:/app/pipelines
  restart: always

I also tried above setup but without any of the spring options, as the docker tutorial in this repository states with same results.

I have some questions:

1. Is it mandatory having a DB for following the hello world tutorial?
2. Is there any other tutorial might I follow?
3. Is it compatible with Oracle, or just h2 and postgres?

I also tried this tutorial without success, I think I'm missing some steps.

Thanks for your work!

Fixed, responding myself:

spring.datasource.url was not correct, actually it wasn't localhost, it was postgresql://postgres:5432/piper

1. Yes, postgres seems mandatory. Database initialization was also failing, so I executed database table script manually.
