A bundle for Symfony 3/4/5 that allows you to use @Cron annotations to configure when cron should run your console commands.

Uses the Cronos library to do the actual output and updating.

Run the composer require command:

$ php composer.phar require mybuilder/cronos-bundle

Enable the bundle in the app/AppKernel.php for Symfony 3:

public function registerBundles(): array
{
    return [
        new MyBuilder\Bundle\CronosBundle\MyBuilderCronosBundle(),
    ];
}

Enable the bundle in the config/bundles.php for Symfony 4/5:

return [
    MyBuilder\Bundle\CronosBundle\MyBuilderCronosBundle::class => ['all' => true],
];

You can add the following to your config.yml (Symfony 3) / packages/my_builder_cronos.yaml (Symfony 4/5) to configure the package.

my_builder_cronos:
    exporter:
        key: unique-key
        mailto: [email protected]
        path: /bin:/usr/local/bin
        executor: php
        console: bin/console
        shell: /bin/bash

The first step is to add the use case for the annotation to the top of the command you want to use the @Cron annotations in.

use MyBuilder\Bundle\CronosBundle\Annotation\Cron;

Then add to the phpdoc for the command class the '@Cron' annotation which tells cron when you want it to run. This example says it should be run on the web server, every 5 minutes, and we don't want to log any output.

/**
 * Command for sending our email messages from the database.
 *
 * @Cron(minute="/5", noLogs=true, server="web")
 */
class SendQueuedEmailsCommand extends Command {}

The whole point of cron is being able to specify when a script is run therefore there are a lot of options.

You should read the general cron info for a general idea of cron and what you can use in these time fields.

Please note You CANNOT use */ in the annotations, if you want */5 just put /5 and Cronos will automatically change it to */5.

You should run app/console cronos:dump and review what the cron file would look after it has been updated. If everything looks ok you can replace your crontab by running the command below.

app/console cronos:replace

You can also limit which commands are included in the cron file by specifying a server, and it will then only show commands which are specified for that server.

app/console cronos:dump --server=web
app/console cronos:replace --server=web

You can choose which environment you want to run the commands in cron under like this.

app/console cronos:replace --server=web --env=prod

• When a cron line is executed it is executed with the user that owns the crontab, but it will not execute any of the users default shell files so all paths etc need to be specified in the command called from the cron line.
• Your crontab will not be executed if you do not have usable shell in /etc/passwd
• If your jobs don't seem to be running check the cron daemon is running, also check your username is in /etc/cron.allow and not in /etc/cron.deny.
• Environmental substitutions do not work, you cannot use things like $PATH, $HOME, or ~/sbin.
