RabbitMQ supervisor bundle

Symfony bundle to automatically create and update supervisor configurations for php-amqplib/rabbitmq-bundle (and its predecessor oldsound/rabbitmq-bundle) RabbitMQ consumer daemons.

In a nutshell | tl;dr

If you use php-amqplib/rabbitmq-bundle to handle the communication with RabbitMQ, just install supervisor, add this bundle and run

$ app/console rabbitmq-supervisor:rebuild

to get a running supervisord instance that automatically manages all your consumer daemons.
When your worker configuration or your code changes, run the command again and all the daemons will be updated.

Installation

Install supervisor. e. g. on debian based distributions via apt-get:

# apt-get install supervisor

Add bundle via composer

$ php composer require phobetor/rabbitmq-supervisor-bundle

This will install the bundle to your project’s vendor directory.

If your are not using Symfony Flex, also add the bundle to your project’s AppKernel:

// app/AppKernel.php
public function registerBundles()
{
    $bundles = [
        // […]
        new Phobetor\RabbitMqSupervisorBundle\RabbitMqSupervisorBundle(),
    ];
}

Symfony 5:

// config/bundles.php
return [
    ...
    Phobetor\RabbitMqSupervisorBundle\RabbitMqSupervisorBundle::class => ["all" => true],
    ...
];

Zero Configuration

RabbitMQ supervisor bundle works out of the box with a predefined configuration. If you leave it this way you will end
up with this directory structure:

supervisor/
└── dev
    ├── logs
    │   ├── stderr.log
    │   └── stdout.log
    ├── supervisord.conf
    ├── supervisord.log
    ├── supervisor.pid
    ├── supervisor.sock
    └── worker
        ├── queue1.conf
        ├── queue2.conf
        ├── queue3.conf
        └── queue4.conf

In symfony 2 and 3 this will be placed inside your app/ directory.

Caution with symfony 4: to not have this inside of your src/ directory you need to set the paths to suit your needs.
E. g. to use the standard structure inside of the var/ directory, use this:

rabbit_mq_supervisor:
    paths:
        workspace_directory:            "%kernel.project_dir%/var/supervisor/%kernel.environment%/"
        configuration_file:             "%kernel.project_dir%/var/supervisor/%kernel.environment%/supervisord.conf"
        pid_file:                       "%kernel.project_dir%/var/supervisor/%kernel.environment%/supervisor.pid"
        sock_file:                      "%kernel.project_dir%/var/supervisor/%kernel.environment%/supervisor.sock"
        log_file:                       "%kernel.project_dir%/var/supervisor/%kernel.environment%/supervisord.log"
        worker_configuration_directory: "%kernel.project_dir%/var/supervisor/%kernel.environment%/worker/"
        worker_output_log_file:         "%kernel.project_dir%/var/supervisor/%kernel.environment%/logs/stdout.log"
        worker_error_log_file:          "%kernel.project_dir%/var/supervisor/%kernel.environment%/logs/stderr.log"

Advanced configuration

To see all configuration options run

$ console config:dump-reference RabbitMqSupervisorBundle

BC break when updating from v1. to v2.

If you used custom commands before version 2.0, you need to update them. In most case you can just remove everything
after the command name.

BC break when updating from v2. to v3.

Commands will by default no longer wait for supervisord to complete. If you need this (e. g. to get feedback on
errors) use the --wait-for-supervisord option.

Usage

Build or rebuild the supervisor and worker configuration and start the daemon:

$ console rabbitmq-supervisor:rebuild

Control the supervisord daemon:

$ console rabbitmq-supervisor:control stop
$ console rabbitmq-supervisor:control start
$ console rabbitmq-supervisor:control restart
$ console rabbitmq-supervisor:control hup
