Cron Bundle
This bundle provides a simple interface for registering repeated scheduled tasks within your application., (*1)
This bundle is tested only against Symfony 2.3, but should work on anything after 2.3, until at least 3.0., (*2)
Installation
- Add the bundle to your project as a composer dependency:
$ composer require aequasi/cron-bundle "~1.0.0"
- Add the bundle to AppKernel:
// AppKernel.php
public function registerBundles()
{
// ...
$bundles = array(
// ...
new Aequasi\Bundle\CronBundle\AequasiCronBundle(),
);
// ...
return $bundles;
}
- Start using the bundle:
$ app/console cron:scan
$ app/console cron:run
Running your cron jobs automatically
This bundle is designed around the idea that your tasks will be run with a minimum interval - the tasks will be run no more frequently than you schedule them, but they can only run when you trigger then (by running app/console cron:run
, or the forthcoming web endpoint, for use with webcron services)., (*3)
To facilitate this, you can create a cron job on your system like this:, (*4)
*/5 * * * * /path/to/symfony/install/app/console cron:run
This will schedule your tasks to run at most every 5 minutes - for instance, tasks which are scheduled to run every 3 minutes will only run every 5 minutes., (*5)
Creating your own tasks
Creating your own tasks with CronBundle couldn't be easier - all you have to do is create a normal Symfony2 Command (or ContainerAwareCommand) and tag it with the @CronJob annotation, as demonstrated below:, (*6)
/**
* @CronJob("PT1H")
*/
class DemoCommand extends Command
{
// ...
}
The interval spec ("PT1H" in the above example) is documented on the DateInterval documentation page, and can be modified whenever you choose.
For your CronJob to be scanned and included in future runs, you must first run app/console cron:scan
- it will be scheduled to run the next time you run app/console cron:run
, (*7)
If you add a new command, you have to run the scan function for it to get picked up, or clear the symfony cache.
