Docker for artisans

"Quick" intro to use Docker in combination with laravel

example 1

cd example1 && \
sh run.sh

example 2

cd example2 && \
sh run.sh

example 3

In addition to the laravel application which gets created through the run.sh script, we created those files and directories:

• docker/web/000-default.conf
• docker/crontab/crontab
• docker/crontab/docker-entrypoint.sh
• .dockerignore
• docker-compose.yml
• Dockerfile
• Dockerfile.dev
• run.sh

I also created an email, event and event listener to demonstrate functionality of the worker container.

cd example3 && \
sh run.sh

The .env file contains a few adjustments to work nicer with the docker environment:

APP_NAME="Docker for Artisans"
APP_URL=http://localhost:8082

LOG_CHANNEL=stderr

DB_CONNECTION=mysql
DB_HOST=db
DB_PORT=3306
DB_DATABASE=laravel
DB_USERNAME=root
DB_PASSWORD=secret

BROADCAST_DRIVER=redis
CACHE_DRIVER=redis
QUEUE_CONNECTION=redis
SESSION_DRIVER=redis
SESSION_LIFETIME=120
SESSION_ENCRYPT=true

REDIS_HOST=redis

MAIL_DRIVER=smtp
MAIL_HOST=maildev
MAIL_PORT=25
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null
MAIL_FROM_NAME="BoonWeb"
MAIL_FROM_ADDRESS="[email protected]"

Don't use Apache for Worker/Cron containers - it's just useless overhead!

Testing events/emails with queues

First go into the database container: docker-compose exec db bash And connect to MariaDB: mysql -uroot -psecret Then create the database schema: create database laravel;

Now you can run migrations:

docker-compose exec app bash

# Inside the App container:
php artisan queue:table
php artisan migrate

Then open tinker:

php artisan tinker

And create a new mail

$mailer = app()->make(Illuminate\Mail\Mailer::class);
$mail = new App\Mail\TestMail();
$mailer->queue($mail);

Or test with an event

event(new App\Events\TestEvent);

Build for production

Just an example with default Dockerfile:

docker build -t links-der-isar/docker-for-artisans:1.3.945 .
