To run jobs in sequence order in Laravel you can make use of Job chaining. To achieve this you will have to make use of the Bus facade and calling the "chain" method.
By making use of this method if one job fails to process the whole sequence will fail to process hence making the flow optimal for processing subsequence tasks.
To define the jobs you can define the code as follows.

Laravel Bus Chain
To define the jobs you can define the code as follows.
<?php
use App\Jobs\ProcessImage;
use App\Jobs\OptimseImage;
use App\Jobs\ReleaseImage;
use Illuminate\Support\Facades\Bus;
Bus::chain([
new ProcessImage,
new OptimseImage,
new ReleaseImage,
])->dispatch();Passing Closure to Jobs Chain
To pass a closure to the jobs chain you can define your code like below.
<?php
Bus::chain([
new ProcessImage,
new OptimseImage,
function () {
Image::update(...);
},
])->dispatch();Chain Connection and Queue in Laravel
To specify the connection and queue in the Jobs chain you can chain the method using the "onConnection" and "onQueue" and passing the value as the method parameter.
<?php
Bus::chain([
new ProcessImage,
new OptimseImage,
new ReleaseImage,
])->onConnection('redis')->onQueue('podcasts')->dispatch();Do note that you can also catch any failed job using the "catch" method.
<?php
Bus::chain([
new ProcessImage,
new OptimseImage,
new ReleaseImage,
])
->onConnection('redis')
->onQueue('podcasts')
->catch(function (Throwable $e) {
// A job within the chain has failed...
})
->dispatch();
