我遇到了与this question相同的问题，rabbitmq在开始连接的同一秒就断开了连接。我在github上有一个最小的项目。
这是一个Spring Boot项目，其中运行了两个Docker容器。一个使用RMQ，一个使用psql。在运行项目时使用容器没有问题，只是rabbitmq测试容器似乎不稳定。我确实尝试将容器 Package 在一个通用容器中，结果相同。
第一个测试，看看容器是否启动和运行通过，所以它似乎是一些与amqp连接只。
设定类别：

@SpringBootTest(classes = TestContainersDemoApplication.class)
@Testcontainers
@AutoConfigureMockMvc
@ExtendWith(SpringExtension.class)
public abstract class TestContainersConfig  {

    @Autowired
    public MockMvc mockMvc;

    @Container
    public static final RabbitMQContainer rabbitMQContainer = new RabbitMQContainer("rabbitmq:3.8-management-alpine");

    @Container
    public static PostgreSQLContainer sqlContainer = new PostgreSQLContainer("postgres:latest")
                .withDatabaseName("demo")
                .withUsername("postgres")
                .withPassword("postgres");

    @DynamicPropertySource
    static void registerProperties(DynamicPropertyRegistry dynamicPropertyRegistry) {
        dynamicPropertyRegistry.add("spring.datasource.url",  () -> sqlContainer.getJdbcUrl());
        dynamicPropertyRegistry.add("spring.datasource.username", () -> sqlContainer.getUsername());
        dynamicPropertyRegistry.add("spring.datasource.password", () -> sqlContainer.getPassword());
        dynamicPropertyRegistry.add("spring.rabbitmq.host", rabbitMQContainer::getHost);
        dynamicPropertyRegistry.add("spring.rabbitmq.port", rabbitMQContainer::getAmqpPort);
    }

    static  {
        Startables.deepStart(Stream.of(rabbitMQContainer, sqlContainer)).join();
    }
}

堆栈跟踪似乎与链接的问题相同：
