Set up RabbitMQ service

The Message Queue Framework (MQF) is a system within Magento Commerce that allows a module to publish messages to queues. It also defines the consumers that will receive the messages asynchronously.

The MQF uses RabbitMQ as the messaging broker, which provides a scalable platform for sending and receiving messages. It also includes a mechanism for storing undelivered messages. RabbitMQ is based on the Advanced Message Queuing Protocol (AMQP) 0.9.1 specification.

We support RabbitMQ version 3.5.

If you prefer using an existing AMQP-based service, like RabbitMQ, instead of relying on Magento Commerce Cloud to create it for you, use the QUEUE_CONFIGURATION environment variable to connect it to your site.

You can use the following instructions for service setup on Magento Commerce Cloud Pro Integration environments and Starter environments, including master branch. You must submit a support ticket to configure the service on Pro Production and Staging environments. See Services.

Add RabbitMQ in services.yaml and

To enable RabbitMQ, add the following code with your installed version and allocated disk space in MB to the .magento/services.yaml file.

    type: rabbitmq:<version>
    disk: 1024

To configure the relationships for the environment variable, set a relationship in your file. For example:

    rabbitmq: "rabbitmq:rabbitmq"

Merge and deploy the code to set the configurations for RabbitMQ. For information on how these changes affect your environments, see services.yaml.

Connect to RabbitMQ for debugging

For debugging purposes, it is useful to directly connect to a service instance in one of the following ways:

Connect from your local development environment

You can do this using SSH tunneling:

  1. Use SSH to log in to the Integration environment with RabbitMQ installed and configured.

  2. Log in to the Magento Cloud CLI and project:

    magento-cloud login
  3. Open a tunnel to the application.

    magento-cloud tunnel:open
  4. Verify the relationships.

  5. Enable local port forwarding to RabbitMQ.

    ssh -L <port-number>:mq.internal:<port-number> <project-ID>-<branch-ID>
  6. While the session is open, you can start a RabbitMQ client of your choice from your local workstation, configured to connect to the localhost:<portnumber using the username and password you found in the relationship variable. For this example, you would use localhost:5672.

Connect from the application

To connect to RabbitMQ running in an application, you need to install a client such as amqp-utils as a project dependency in your file.

For example,

        amqp-utils: "0.5.1"

Then, when you log in to your PHP container, you enter any amqp- command available to manage your queues.

Connect from your PHP application

To connect to RabbitMQ using your PHP application, add a PHP library (like PHP AMQPlib) to your source tree.
