What happened?

Hi!
I start RabbitMQContainer like this

        @Bean
        RabbitMQContainer rabbitMQContainer(DynamicPropertyRegistry registry) {

            var imageName = DockerImageName.parse("library/rabbitmq:3-management")
                    .asCompatibleSubstituteFor("rabbitmq");
            var container = new RabbitMQContainer(imageName)
                    .withEnv(Map.of( 
                    "RABBITMQ_DEFAULT_USER", "user", 
                    "RABBITMQ_DEFAULT_PASS", "pass", 
                    "RABBITMQ_DEFAULT_VHOST", "vhost" 
            ));
            registry.add("property.port", container::getAmqpPort);
            registry.add("property.host", container::getHost);
            return container;
        }
    }

It starts normally. But any try to connect to rabbitmq end with error. Test log contains
ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. For details see the broker logfile
RabbitMQ's log contains

2024-11-26 14:36:03.282923+00:00 [error] <0.839.0> Error on AMQP connection <0.839.0> (192.168.64.1:49308 -> 172.26.0.3:5672, state: starting):
2024-11-26T14:36:03.283748836Z 2024-11-26 14:36:03.282923+00:00 [error] <0.839.0> PLAIN login refused: user 'user' - invalid credentials

Even though I can't authorize into admin panel (http://localhost:15672), I get an relevant error about incorrect creds.

But when I start container in traditional way docker run -d -p '15672:15672' --hostname my-rabbit --name some-rabbit -e RABBITMQ_DEFAULT_USER=user -e RABBITMQ_DEFAULT_PASS= pass -e RABBITMQ_DEFAULT_VHOST=vhost rabbitmq:3-management I don't get any problems with connection and authorization.

Relevant log output

How are you setting rabbitmq credentials in spring? RABBITMQ_DEFAULT_USER and RABBITMQ_DEFAULT_PASS are the right env vars to set the credentials in the container. So, the client must use the same value user and pass. Can you provide a minimal reproducer, please?

@eddumelendez Hi! Thanks for response!
I built a little example https://github.com/FoKas90/testcontainers-rabbitmq-bug reproducing unexpectable behaviour

[eddumelendez]

The code shared is different than the snippet reported in this issue. I've merged #9571, which should fix the issue with ServiceConnection

I wanted emphasize the minimal configuration with defaults still doesn't work (to my mind). Thank you for fast fix!
