Weird problem using PHP-WORKER with queue to create pdf has embeded images

[quangnhattran]

   Hello

Laravel version 6.0 with dependency simplesoftwareio/simple-qrcode to generate pdf
I am using Laradock to run Nginx, PHP 7.3, MariaDB, php-worker and Redis.
I setup QUEUE_DRIVER=redis and laravel-worker.conf as below:
[program:myproject-worker] process_name=%(program_name)s_%(process_num)02d command=php /var/www/myproject/artisan queue:work redis --tries=1 autostart=true autorestart=true numprocs=2 user=root redirect_stderr=true stdout_logfile=/var/www/myproject/worker.log
When I run docker-compose up php-worker, the job was failed with error Call to undefined function BaconQrCode\Renderer\Image\imagecreatetruecolor().
The weird thing is if I stop php-worker but manually run php artisan queue:work redis --tries=1 then job processed successfully.
Do you think it is a bug or something?
Thanks :)

After checking Dockerfile of php-worker and know it uses PHP Alpine without PHP GD ext enabled by default. After edit Dockerfile to add command to include PHP GD ext. My jobs processed by php-worker without any problem.
