Laravel issue with envvars

Hello at all,

I’m deploying a Laravel application with DO Apps Platform. Deployment works but I have an issue with the App environment variables.

I did set in the DO Console

DB_HOST=${db-mysql-fra1.HOSTNAME}
DB_PORT=${db-mysql-fra1.PORT}
DB_DATABASE=${db-mysql-fra1.DATABASE}
DB_USERNAME=${db-mysql-fra1.USERNAME}
DB_PASSWORD=${db-mysql-fra1.PASSWORD}

In the build process, I added a php artisan migrate --force but it fails with: php_network_getaddresses: getaddrinfo for ${db-mysql-fra1.HOSTNAME} failed. The envvar is not translated. Once launched, I have the same issue with php-fpm. If I do:

$ php artisan tinker
> echo env('DB_HOST'); // db-mysql-fra1-user.b.db.ondigitalocean.com
> echo config('database.connections.mysql.host'); // ${db-mysql-fra1.HOSTNAME}
> exit
$ php artisan config:clear
$ php artisan tinker
> echo config('database.connections.mysql.host'); // db-mysql-fra1-user-0.b.db.ondigitalocean.com

So I must manually clear the config cache to make it work. Of course, I added the php artisan config:clear in the build phase commands but same:

php artisan cache:clear
php artisan config:clear
php artisan migrate --force
npm run build

I must add that I previously set a php artisan optimize in the build commands but I removed it as I thought this was the problem.

Thanks in advance,

Axel
