Cron functions for Deployer

Simple handling of cronjobs in your deployment process using the Cron builder library.

Installation

composer require setono/deployer-cron

Usage

The easiest usage is to include the cron recipe which hooks into default Deployer lifecycle:

<?php
// deploy.php

require_once 'recipe/cron.php';

Deployer parameters

The following Deployer parameters are defined:

Parameter	Description	Default value
cron_config_dir	The directory to search for cronjob config files	etc/cronjobs
cron_delimiter	The marker in the crontab file that delimits the generated cronjobs from manually added cronjobs	The stage. If not set, the default is prod.
cron_user	The user onto which the crontab should be added (default is remote_user)	get('http_user') if you are root, else ''

Cron builder context

The cron builder context is set to the Deployer configuration parameters. This means you can use variables in your cronjob config files. For example:

<?php
# etc/cronjobs/jobs.php

declare(strict_types=1);

use Setono\CronBuilder\Context;
use Setono\CronBuilder\CronJob;

return static function (Context $context): iterable {
    yield new CronJob('0 0 * * *', '/usr/bin/php {{ release_path }}/send-report.php', 'Run every day at midnight');

    if ($context->get('stage') === 'prod') {
        yield new CronJob('0 0 * * *', '/usr/bin/php {{ release_path }}/process.php');
    }
};

Notice the usage of release_path and stage in the cronjob config file.
