Intro to BCC Resque Bundle

The BCC resque bundle provides integration of php-resque to Symfony2. It is inspired from resque, a Redis-backed Ruby library for creating background jobs, placing them on multiple queues, and processing them later.

Features:

Creating a Job, with container access in order to leverage your Symfony services
Enqueue a Job wih parameters on a given queue
Creating background worker on a given queue
A UX to monitor your queues, workers and job statuses

TODOs:

Log management
Integrate scheduler
Job status tracking
Redis configuration
Localisation
Tests

Installation and configuration:

Requirements

Make sure you have redis installed on your machine: http://redis.io/

Get the bundle

Add to your bcc-resque-bundle to your dependencies:

{
    "require": {
        ...
        "bcc/resque-bundle": "dev-master"
    }
    ...
}

And make a php composer.phar update.

Add BCCResqueBundle to your application kernel

<?php

    // app/AppKernel.php
    public function registerBundles()
    {
        return array(
            // ...
            new BCC\ResqueBundle\BCCResqueBundle(),
            // ...
        );
    }

Import the routing configuration

Add to your routing.yml:

# app/config/routing.yml
BCCResqueBundle:
    resource: "@BCCResqueBundle/Resources/config/routing.xml"
    prefix:   /resque

You can customize the prefix as you wish.

You can now acces the dashboard at this url: /resque

Optional, set configuration

You may want to add some configuration to your config.yml

# app/config/config.yml
bcc_resque:
    class: BCC\ResqueBundle\Resque  # the resque class if different from default
    vendor_dir: %kernel.root_dir%/../vendor  # the vendor dir if different from default
    redis:
        host: localhost                      # the redis host
        port: 6379                           # the redis port
        database: 0                          # the redis database

Creating a Job

A job is a subclass of the BCC\ResqueBundle\Job class. You also can use the BCC\Resque\ContainerAwareJob if you need to leverage the container during job execution. You will be forced to implement the run method that will contain your job logic:

<?php

namespace My;

use BCC\ResqueBundle\Job;

class MyJob extends Job
{
    public function run($args)
    {
        \file_put_contents($args['file'], $args['content']);
    }
}

As you can see you get an $args parameter that is the array of arguments of your Job.

Adding a job to a queue

You can get the resque service simply by using the container. From your controller you can do:

<?php

// get resque
$resque = $this->get('bcc_resque.resque');

// create your job
$job = new MyJob();
$job->args = array(
    'file'    => '/tmp/file',
    'content' => 'hello',
);

// enqueue your job
$resque->enqueue($job);

Running a worker on a queue

Just by using the following command you will create a worker on the default queue: app/console bcc:resque:worker-start default

You can run a worker on several queues just separeate then using ,. If you want a worker on every queues, just use *. You can also run a worker foreground by adding the --foreground option;

More features

Changing the queue

You can change a job queue just by setting the queue field of the job:

From within the job:

<?php

namespace My;

use BCC\ResqueBundle\Job;

class MyJob extends Job
{
    public function __construct()
    {
        $this->queue = 'my_queue';
    }

    public function run($args)
    {
        ...
    }
}

Or from outsite the job:

<?php

// create your job
$job = new MyJob();
$job->job = 'my_queue';

Access the container from inside your job

Just extend the ContainerAwareJob:

<?php

namespace My;

use BCC\ResqueBundle\ContainerAwareJob;

class MyJob extends ContainerAwareJob
{
    public function run($args)
    {
        $doctrine = $this->getContainer()->getDoctrine();
        ...
    }
}

Stop a worker

Use the app/console bcc:resque:worker-stop command.

No argument will display running workers that you can stop.
Add a worker id to stop it: app/console bcc:resque:worker-stop ubuntu:3949:default
Add the --all option to stop all the workers.
