laravel graceful exit queue

LgeQueue

laravel graceful exit queue, _(*1)

usage scenario

need the queue to exit

The recommanded method to graceful restart a queue is using these commands, _(*2)

php artisan down
php artisan queue:restart

But, sometimes, we still want the queue to autoexit when necessary. For example, our team using docker to deploy the software want to determine the queue worker has finished current job and stop doing anything before we remove the old version and deploy a new one., _(*3)

use multi-processes to run queue

When some queue has more jobs than others, it may be good to set it to an indenpendent process. We make a new artisan command to make such complex supervisor configurations., _(*4)

install

1. You can install with composer, _(*5)

   composer reqiure lekongkong/lgequeue, _(*6)

2. Please replace the queue service provider, done., _(*7)

config

Add this config sample to your queue.php config file., _(*8)

'supervisor' => [

    //the dir to put logs of supervisor and jobs
    'logs' => '/var/logs', 

    //the artisan file path
    'artisan' => '/path/to/artisan', 

    // the dir where you store jobs
    'jobs' => '/path/to/Jobs',

    //jobs in one group will be put in one processes
    'groups' => [ 
        [
            'jobs' => [\app\Jobs\SendPush::class],
        ],
        [
            'jobs' => [\app\Jobs\AfterAdSaved::class, \app\Jobs\SelectAd::class, \app\Jobs\SendChatMessage::class],
            'processNum' => 1,
        ],
    ],
],

addtional config

you may add a new config handler to failed in queue.php, which will enable your own failed job provider., _(*9)

'failed' => [
    'handler' => \LgeQueue\FailedJobProvider::class
],

usage

make supervisor config and start

php artisan superconf > supervisor.conf
supervisord -c supervisord.conf

call the queue processes to exit

php artisan down

coding tips

• You can extend the Job class of this repo rather than the original one, which containing a convenient method onSelf to push the job to the queue named by its class. Otherwise you may have to adjust the groups config to add your own queue name, not the class name as in sample.
• Besides the grouped jobs queue processes, there will be a default queue process using the default queue name, configed in queue.php.
• Tested in redis queue backend, should work appropriate on other backend.
