docker-compose up -d
DB_HOST=mysql - This name comes from the MySQL service we created in the docker-compose.yml file, and is used in the Docker network to reference the service from other containers.
APP_URL=http://localhost:8080 - Add in the port number you’ve exposed in our nginx container to keep this pointing at a resolvable address.
All you’re going to do is use 127.0.0.1 as the host, along with the port you’ve exposed under the MySQL service in our docker-compose.yml file (which for this example we’ve kept as the default 3308)

Laravel utilizes the command line fairly often for things like migrations, queues, and tests. Executing these on our Docker network is super easy using docker-compose’s exec command.
docker-compose exec php php /var/www/artisan migrate
