How to set the container hostname property for RabbitMQ Docker containers?

[CyrusZhou-CN]

I am using the following code to create three RabbitMQ Docker containers and want to test their behavior as nodes. I would like to set the hostname property for the containers to easily identify and manage them.

var builder = DistributedApplication.CreateBuilder(args);

var rabbitMq = builder.AddRabbitMQContainer("EventBus");
rabbitMq.WithEnvironment("RABBITMQ_ERLANG_COOKIE", "secretcookie");
rabbitMq.WithVolumeMount("rabbitmq-node.config", "/etc/rabbitmq/rabbitmq.config");

var rabbitMq1 = builder.AddRabbitMQContainer("EventBus1");
rabbitMq1.WithEnvironment("RABBITMQ_ERLANG_COOKIE", "secretcookie");
rabbitMq1.WithVolumeMount("rabbitmq-node.config", "/etc/rabbitmq/rabbitmq.config");

var rabbitMq2 = builder.AddRabbitMQContainer("EventBus2");
rabbitMq2.WithEnvironment("RABBITMQ_ERLANG_COOKIE", "secretcookie");
rabbitMq2.WithVolumeMount("rabbitmq-node.config", "/etc/rabbitmq/rabbitmq.config");

How should I set the hostname property to facilitate testing and managing these RabbitMQ containers?

docker-compose.yml

version: '3.8'

services:
  rabbitmq-node1:
    image: "rabbitmq:3-management"
    container_name: "rabbitmq-node1"
    hostname: rabbitmq-node1
    ports:
      - "5672:5672"
      - "15672:15672"
    environment:
      RABBITMQ_ERLANG_COOKIE: "secretcookie" 
    volumes:
      - ./rabbitmq-node1.config:/etc/rabbitmq/rabbitmq.config
    networks:
      - rabbitmq-cluster

  rabbitmq-node2:
    image: "rabbitmq:3-management"
    container_name: "rabbitmq-node2"
    hostname: rabbitmq-node2
    ports:
      - "5673:5672"
      - "15673:15672"
    environment:
      RABBITMQ_ERLANG_COOKIE: "secretcookie"
    volumes:
      - ./rabbitmq-node2.config:/etc/rabbitmq/rabbitmq.config
    networks:
      - rabbitmq-cluster

  rabbitmq-node3:
    image: "rabbitmq:3-management"
    container_name: "rabbitmq-node3"
    hostname: rabbitmq-node3
    ports:
      - "5674:5672"
      - "15674:15672"
    environment:
      RABBITMQ_ERLANG_COOKIE: "secretcookie"
    volumes:
      - ./rabbitmq-node3.config:/etc/rabbitmq/rabbitmq.config
    networks:
      - rabbitmq-cluster

networks:
  rabbitmq-cluster:
    driver: bridge
