Aspire apps and RabbitMQ, add rabbitmq.conf / definitions.json

[ramonduraes]

I have a /config/rabbitmq.conf file and another /config/definitions.json file that I use in traditional docker compose to configure my RabbitMQ. How to apply them?

File 01: config/rabbitmq.conf

management.load_definitions = /etc/rabbitmq/definitions.json

File 02: config/definitions.json

{
  "vhosts": [
    {
      "name": "/"
    }
  ],
  "queues": [
    {
      "name": "queue1",
      "vhost": "/",
      "durable": true
    },
    {
      "name": "queue2",
      "vhost": "/",
      "durable": true
    }
  ],
  "exchanges": [
    {
      "name": "abc",
      "vhost": "/",
      "type": "direct",
      "durable": true
    }
  ],
  "bindings": [
    {
      "source": "abc",
      "vhost": "/",
      "destination": "queue1",
      "destination_type": "queue",
      "routing_key": "key1"
    },
    {
      "source": "abc",
      "vhost": "/",
      "destination": "queue2",
      "destination_type": "queue",
      "routing_key": "key2"
    }
  ]
}

My Code

var builder = DistributedApplication.CreateBuilder(args);

var rabbitmqConfigPath = Path.Combine(Directory.GetCurrentDirectory(), @"config\rabbitmq.conf");
var rabbitmqDefinitionsPath = Path.Combine(Directory.GetCurrentDirectory(), @"config\definitions.json");

var rabbitmq = builder.AddRabbitMQ("rabbitmq")
                      .WithManagementPlugin()
                      .WithVolume(rabbitmqConfigPath, "/etc/rabbitmq/rabbitmq.conf")
                      .WithVolume(rabbitmqDefinitionsPath, "/etc/rabbitmq/definitions.json");

Error

What is the recommendation for passing the configuration files that are in a folder in the host project?

@ramonduraes the first argument to the WithVolume method is actually the name of the volume, not a path. What you want to do here is probably use the WithBindMount method instead.

[ramonduraes]

The ".WithBindMount" option worked in the local environment. When publishing to Azure, it did not create queues. Is it necessary to add some persistence to the configuration?

[davidfowl]

Are you trying to use rabbitmq for real in production? Or is this just a dev/test scenario?

[ramonduraes]

I'm just testing to evaluate the journey in the developer environment and after publishing to Azure.
