Proposal

In order to fix cleanly spring-projects/spring-boot#43174, would it be possible to unite DockerComposeContainer and Container under a common empty interface?

Hi, thanks for the suggestion. DockerComposeContainer and ComposeContainer are utilities to use docker compose in two ways: containerised or local cli. The main difference with other Container implementations is docker compose in containerised mode doesn't keep running, it just execute the command and then shutdown. I don't think, implementing Container interface will fix the spring boot issue, but we need to think how spring boot will resolve the connection details given those are obtained via service name from compose file in Testcontainers. Using environment.getContainerByServiceName(serviceName); we can get the ContainerState for each service declared in compose file.
