Can I run queue jobs manually without run artisan queue:listen?

Hello,

First of all, I like to apologize for the following question if this seems to be weird.

I am totally new on Lumen, and I just build the DB tables ( jobs, failed_jobs ) required for the queues.

Also, I built the following job that does nothing impressive ( at least not yet ):

<?php

namespace App\Jobs;

class InsertEvents extends Job {
    public function __construct() {}

    public function handle() {}
}

In addition, in my controller class I have entered the following code in order to insert the new jobs in the jobs table:

$job = ( new InsertEvents( 'Job Body' ) )->onQueue( 'events' );
dispatch( $job );

Until now, the work is done very nice. I run my controller action and I insert the jobs in the jobs table.

Now, what I like to ask, is if it's possible to run the Job Workers manually without using the artisan queue:listen.

The reason I am asking for that is because I don't know a lot from server management, and thus I am not able to run the command on my clients' server. Yes, I know it seems to be very simple the configuration, but I not aware of debugging the server in case that something goes wrong with it and that's why I am looking to avoid it.

In addition, locally, I have run both the php artisan queue:work and the php artisan queue:listen & but I didn't see any changes in my jobs table. What supposed to happen once I run the commands? Should the records removed one by one from the DB because it should get processed by the Worker?

Finally, when I mean if there's a way to run the jobs manually, I mean to install a CRON Jobs on my clients' server to execute a call in a given URL of the app, and the controller responsible for this URL to execute the next job in the queue.

Kind regards Merianos Nikos
