In Laravel, you can specify the maximum number of times a job can be attempted by using the --tries option in the onQueue method when dispatching the job.
MyJob::dispatch()->onQueue('my-queue')->tries(3);
In this example, the tries method is used to specify that the job can be attempted a maximum of 3 times.
You can also specify the number of attempts for all jobs within a particular queue by modifying the maxTries property in the config/queue.php configuration file.
'my-queue' => [
'connection' => 'redis',
'maxTries' => 3,
'timeout' => 60,
],
In this case, all jobs dispatched to the 'my-queue' will have a maximum of 3 attempts.
When a job fails, Laravel will automatically attempt to retry it based on the number of tries specified. If the maximum number of attempts is reached without success, Laravel will fire the failed event for the job. You can listen to this event to handle failed jobs and perform any necessary actions.
