Describe the bug

I want to test SSL in RabbitMQ. I used AddRabbitMQ with an additional call to WithEndpoint.

Example:

var rabbitMqPassword = builder.AddParameter("RabbitMqPassword");

var rabbitMq = builder.AddRabbitMQ("rabbitmq", password: rabbitMqPassword)
    .WithLifetime(ContainerLifetime.Persistent)
    .WithBindMount("rabbitmq.conf", "/etc/rabbitmq/rabbitmq.conf")
    .WithBindMount("rabbitmq.key", "/etc/rabbitmq/certs/rabbitmq.key")
    .WithBindMount("rabbitmq.crt", "/etc/rabbitmq/certs/rabbitmq.crt")
    .WithEndpoint(55671, 5671, "tcp", "ssl")
    .WithManagementPlugin();

When I run docker ps, I see a different port allocated other than 55671.

docker ps
CONTAINER ID   IMAGE                     COMMAND                  CREATED          STATUS          PORTS                                                                                                                               NAMES

here is my AppHost and its references

<Project Sdk="Microsoft.NET.Sdk">
  <Sdk Name="Aspire.AppHost.Sdk" Version="9.2.1" />

  <PropertyGroup>
    <OutputType>Exe</OutputType>

  </ItemGroup>

</Project>

Expected Behavior

To get the port 55671 defined in WithEndpoint(55671, 5671, "tcp", "ssl")

Steps To Reproduce

1. Create a web project in .NET 8
2. Create an Aspire AppHost and reference the web app
3. Add Aspire.Hosting.RabbitMQ
4. Add RabbitMQ in the orchestration (see example above)
5. Run docker ps to check the port mappings

RTFM, thanks! =)

I get the Proxy idea now.
Disabling it did the trick.

The documentation for port argument confused me at first.
