DockerComposeContainer not starting Exposed Service

The latest release of testcontainers (1.15.0) seems to have introduced a bug with DockerComposeContainer where the command used to start containers is missing specified exposed services.

What happens is it seems that the docker-compose up command is missing the db service. For some reason it isn't written out as part of the command.

Command: up -d --scale scaling=2 scaled_service
Specific log: 10:34:52.774 [main] INFO 🐳 [docker-compose] - Local Docker Compose is running command: up -d --scale scaling=2 scaled_service

Example

Compose File

version: '3'

services:
  db:
    image: postgres:11
    environment:
      - POSTGRES_DB=test
      - POSTGRES_USER=test
      - POSTGRES_PASSWORD=test
    ports:
      - "5432:5432"
  scaled_service:
    image: alpine:latest

                .withScaledService("scaled_service", 2)

                        .withStartupTimeout(Duration.of(60, SECONDS)));

        container.start();

        // Will not reach this point will fail
        container.stop();
    }
}

Inizia da DockerComposeContainer.start e dall’assemblaggio del comando mostrato dallo stack trace, quindi confrontalo con il test-compose.yml fornito e con l’esempio ReproduceBug.java. Esegui la riproduzione e verifica che l’uso di withExposedService includa db nel comando docker-compose generato e consenta il completamento dell’avvio.
