rabbitmnq: Can't declare binding with routing key

[oneiros-de]

I'm using org.testcontainers:rabbitmq 1.17.1 with Spring Boot 2.6.7.
I'm trying to create a test container with a binding with a routing key:

  private static final String RABBITMQ_VHOST = "mo_messaging";
  private static final String RABBITMQ_USER = "hermesmo";
  private static final String RABBITMQ_EXCHANGE = "inboundExchange";
  private static final String RABBITMQ_QUEUE = "ss7InboundQueue";
  @Container
  private static final RabbitMQContainer RABBIT_MQ_CONTAINER =
      new RabbitMQContainer(DockerImageName.parse("rabbitmq:3.7.25-management-alpine"))
          .withVhost(RABBITMQ_VHOST, true)
          .withUser(RABBITMQ_USER, "password")
          .withPermission(RABBITMQ_VHOST, RABBITMQ_USER, ".*", ".*", ".*")
          .withExchange(RABBITMQ_VHOST, RABBITMQ_EXCHANGE, ExchangeTypes.TOPIC, false, false, true,
              Collections.emptyMap())
          .withQueue(RABBITMQ_QUEUE)
          .withBinding(RABBITMQ_EXCHANGE, RABBITMQ_QUEUE, Collections.emptyMap(), "ss7", DestinationType.QUEUE.name());

This fails. The (extensive) log shows an error:

15:20:43.585 [main] ERROR 🐳 [rabbitmq:3.7.25-management-alpine] - Could not execute command [rabbitmqadmin, declare, binding, source=inboundExchange, destination=ss7InboundQueue, routing_key=ss7, destination_type=QUEUE, arguments={}]: Traceback (most recent call last):

    raise Exception("Received response %d %s for path %s\n%s"
Exception: Received response 500 Internal Server Error for path /api/bindings/%2F/e/inboundExchange/Q/ss7InboundQueue
b''

When I use

.withBinding(RABBITMQ_EXCHANGE, RABBITMQ_QUEUE);

this fails with

15:31:19.997 [main] ERROR 🐳 [rabbitmq:3.7.25-management-alpine] - Could not execute command [rabbitmqadmin, declare, binding, source=inboundExchange, destination=ss7InboundQueue]: *** Not found: /api/bindings/%2F/e/inboundExchange/q/ss7InboundQueue

Am I doing something wrong or is this a bug?

Hi @oneiros-de
I would assume ExchangeTypes.TOPIC value is topic and DestinationType.QUEUE.name() is queue? I tried with QUEUE and got the same error, using it with lowercase the stacktrace is not displayed anymore.

I can see that you the queue and binding will not work for you because the exchange already belongs to a vhost. So, to make it work everything should be in the vhost.

As a workaround you can run rabbitmqadmin commands just like thiscontainer.execInContainer("rabbitmqadmin", "list", "queues").getStdout() in order to create a queue and binding in the same vhost where the exchange is.

I've changed the code to lowercase the constants:

.withExchange(RABBITMQ_VHOST, RABBITMQ_EXCHANGE, ExchangeTypes.TOPIC.toLowerCase(Locale.ROOT), false, false, true,
              Collections.emptyMap())
          .withQueue(RABBITMQ_QUEUE)
          .withBinding(RABBITMQ_EXCHANGE, RABBITMQ_QUEUE);

but it still fails:

10:36:28.358 [main] ERROR 🐳 [rabbitmq:3.7.7-management-alpine] - Could not execute command [rabbitmqadmin, declare, binding, source=inboundExchange, destination=ss7InboundQueue]: *** Not found: /api/bindings/%2F/e/inboundExchange/q/ss7InboundQueue

I'm following the pattern from RabbitMQContainerTest.shouldStartTheWholeEnchilada

Not sure if you read my previous comment or it was not clear enough

I can see that you the queue and binding will not work for you because the exchange already belongs to a vhost. So, to make it work everything should be in the vhost.

This is the reason why the second attempt using .withBinding(RABBITMQ_EXCHANGE, RABBITMQ_QUEUE); didn't work

RabbitMQContainerTest.shouldStartTheWholeEnchilada doesn't add vhost to the exchange as your code suggest.

.withExchange(RABBITMQ_VHOST, RABBITMQ_EXCHANGE, ExchangeTypes.TOPIC.toLowerCase(Locale.ROOT), false, false, true,
              Collections.emptyMap())

If the RABBITMQ_VHOST is removed there then it should work with the queue and the binding.

I've submitted #5348 in order to add useful methods to deal with this in the future.

Ah, thanks. Yes, I overlooked this.

I've submitted #5348 in order to add useful methods to deal with this in the future.

Thanks!

the new methods to create exchange and binding were released with 1.17.2

Just for others who might come upon this issue when searching for the same "Could not execute command" error: I ran into what had appeared to be this same issue when using rabbitmq:3.13.7-alpine as the image. Using rabbitmq:3.13.7-management-alpine instead worked, since of course rabbitmqadmin is required.
