I'm new here and that's my 1st question so tell me if anything is wrong in the way I put it.
So here's the problem: I'm building a LAMP stack with 3 separate containers for nginx, maiadb and wordpress.
The whole nginx and php-fpm seems to work well, as I can access the site's index and process php pages. Mdb builds the wordpress db and creates a "wordpress@wordpress-php" user with all privileges on it.
It starts to go wrong when I access the site for installation, I get stuck with a : "Error establishing a database connection"
Here is my wp-config.php, that I copy in the wordpress dir inside the container:
<?php
4 define( 'DB_NAME', 'wordpress' );
7 define( 'DB_USER', 'wordpress' );
10 define( 'DB_PASSWORD', 'wordpress' );
15 define( 'DB_HOST', 'mariadb' );
16 define( 'DB_CHARSET', 'utf8' );
17
19 define( 'DB_COLLATE', '' );
20 define('AUTHOR', 'yotillar');
21
22 // Authentication unique keys and salts.
23 define( 'AUTH_KEY', 'key' );
24 define( 'SECURE_AUTH_KEY', 'key' );
25 define( 'LOGGED_IN_KEY', 'key' );
26 define( 'NONCE_KEY', 'key' );
27 define( 'AUTH_SALT', 'salt' );
28 define( 'SECURE_AUTH_SALT', 'salt' );
29 define( 'LOGGED_IN_SALT', 'salt' );
30 define( 'NONCE_SALT', 'salt' );
31
38 $table_prefix = 'wp_';
51 define( 'WP_DEBUG', true );
52 define( 'WP_DEBUG_LOG', true );
53 define( 'WP_DEBUG_DISPLAY', false );
59 if ( ! defined( 'ABSPATH' ) ) {
60 »···define( 'ABSPATH', __DIR__ . '/' );
61 }
64 require_once ABSPATH . 'wp-settings.php';
65 ?>
Here's my docker-compose.yaml:
version: "3.5"

I set the bind-address of mariadb on 0.0.0.0 in ./etc/mysql/mariadb.conf.d/50-se rver.cnf and ./etc/mysql/my.cnf to be sure that th db is indeed listening from every ip.
I think the problem comes from the wp-config.php , but as I understood in a docker-compose environment you can refer to each container with his name instead of ip, and I don't know how I could retrieve mariadb's IP from wordpress-php.
Please help me, thanks in advance to anyone that read that far! ^^
