Crontab generator from JSON

This generator allows you store your cron-tasks config in VCS as a simple JSON-file and install it on server after deployment. You can describe task execution time as a human friendly phrase:

• Every 12 minutes
• Every 22th minute of every hour
• Every day at 10:20

Json-config concepts

Profile - it's an enviroment, for example you can disable some tasks on test server.

Each profile has variables, which will be replaced in command line. It can be path to your framework console.php file or other cli utility.

Jobs - it's your cron commands, described with following properties:

• title - task name
• is_enabled - you can temporaly disable your task
• profiles - on which profiles this job will run
• schedule - human friendly string, describing when job will be executed
• command - shell code, which will be executed

Code sample

try {
    $generator = \Krolikoff\CronGen\Generator::init()->setJson('/path/to/config.json')
        ->generate('YOUR_PROFILE_NAME')->install();
}
catch (\Exception $e) {
    echo $e->getMessage();
}

This example config

{
    "profiles": {
        "local": {
            "variables": {
                "PREFIX": "/usr/bin/php /var/www/domain/console.php"
            }
        },
        "www": {
            "variables": {
                "PREFIX": "/usr/bin/php /var/www/vhosts/domain/public/console.php"
            }
        }
    },
    "jobs": [
        {
            "title": "Stat job",
            "is_enabled" : true,
            "profiles": ["local", "www"],
            "schedule": "every 10 minutes",
            "command": "{PREFIX} admin stats calculate"
        },
        {
            "title": "Download job",
            "is_enabled" : true,
            "profiles": ["www"],
            "schedule": "every day at 5:00",
            "command": "{PREFIX} api download stats"
        },
        {
            "title": "Upload job",
            "is_enabled" : false,
            "profiles": ["local"],
            "schedule": "every 20th minute of every hour",
            "command": "{PREFIX} admin upload photos"
        }
    ]
}

will produce following crontab file for the profile "www":

#Stat job
*/10 * * * * /usr/bin/php /var/www/vhosts/domain/public/console.php admin stats calculate
#Download job
0 5 * * * * /usr/bin/php /var/www/vhosts/domain/public/console.php api download stats
