EoJobQueueBundle

Mongodb ODM implementation for JMSJobQueueBundle which allows to schedule Symfony2 console commands as jobs.

Prerequisites

This version of the bundle requires Symfony 2.1+

Installation

Step 1: Download EoJobQueueBundle using composer

Add EoJobQueueBundle in your composer.json:

{
    "require": {
        "eo/job-queue-bundle": "dev-master"
    }
}

Now tell composer to download the bundle by running the command:

$ php composer.phar update eo/job-queue-bundle

Composer will install the bundle to your project's vendor/eo directory.

Step 2: Enable the bundle

Enable the bundle in the kernel:

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...
        new Eo\JobQueueBundle\EoJobQueueBundle(),
    );
}

Step 3: Change console base application class

Have your app/console use EoJobQueueBundle's Application:

// use Symfony\Bundle\FrameworkBundle\Console\Application;
use Eo\JobQueueBundle\Console\Application;

Step 4 (Optional): Configure bundle

Now that you have properly installed and enabled EoJobQueueBundle, the next step is to configure the bundle to work with the specific needs of your application.

To change the default job class used by the bundle, add the following configuration to your config.yml file

# app/config/config.yml
eo_job_queue:
    job_class: JuliusJobBundle:Job

Setting Up supervisord

For this bundle to work, you have to make sure that one (and only one) instance of the console command eo-job-queue:run is running at all times. You can easily achieve this by using supervisord.

A sample supervisord config might look like this:

[program:eo_job_queue_runner]
command=php %kernel.root_dir%/console eo-job-queue:run --env=prod --verbose
process_name=%(program_name)s
numprocs=1
directory=/tmp
autostart=true
autorestart=true
startsecs=5
startretries=10
user=www-data
redirect_stderr=false
stdout_logfile=%capistrano.shared_dir%/eo_job_queue_runner.out.log
stdout_capture_maxbytes=1MB
stderr_logfile=%capistrano.shared_dir%/eo_job_queue_runner.error.log
stderr_capture_maxbytes=1MB

For testing, or development, you can of course also run the command manually, but it will auto-exit after 15 minutes by default (you can change this with the --max-runtime=seconds option).

Usage

Creating Jobs

Creating jobs is super simple, you just need to persist an instance of Job:

<?php

$job = new Job('my-symfony2:command', array('some-args', 'or', '--options="foo"'));
$dm->persist($job);
$dm->flush($job);

Adding Dependencies Between Jobs

If you want to have a job run after another job finishes, you can also achieve this quite easily:

<?php

$job = new Job('a');
$dependentJob = new Job('b');
$dependentJob->addJobDependency($job);
$dm->persist($job);
$dm->persist($dependentJob);
$dm->flush();

Adding Related Documents to Jobs

If you want to link a job to another document, for example to find the job more easily, the job provides a special many-to-any association:

<?php

$job = new Job('a');
$job->addRelatedDocument($anyDocument);
$dm->persist($job);
$dm->flush();

$dm->getRepository('EoJobQueueBundle:Job')->findJobForRelatedDocument('a', $anyDocument);

Schedule a Jobs

If you want to schedule a job :

<?php

$job = new Job('a');
$date = new DateTime();
$date->add(new DateInterval('PT30M'));
$job->setExecuteAfter($date);
$dm->persist($job);
$dm->flush();
