Docker Compose service suffix changed from `_1` to `-1`

See original GitHub issue

Hi, I’m not sure when this change happened but it seems one of the latest docker-compose desktop version changed the suffix naming pattern for services from _1 to -1

This let’s my tests fail as the lookup doesn’t work anymore

If I change my exposed service setting to -1 like this:

@Container
    val pdf = DockerComposeContainer(...)
        .withLocalCompose(true)
        .withExposedService("pdf-1", 3000) // change from _1 to -1
        .withBuild(true)

The error gets stranger:

...
ContainerLaunchException: Aborting attempt to link to container jjz1pmny2gn9_pdf-1_1 as it is not running

@govardhanaraoganji In Docker Desktop for Windows, this is a setting in their UI. I’d assume there is something similar on Mac.
