This is not expected work requested in #290

Here is the document for Testcontainers support in Spring Boot.
https://docs.spring.io/spring-boot/reference/features/dev-services.html#features.dev-services.testcontainers

You should create a project from Spring Initializr with "Testcontainers" dependency included.

Again, create a project with Spring Initializr using maybe curl and leverage the generated files.
