A docker-compose stack for local web development, which includes:

• Nginx 1.20
• MariaDB 10.5
• PHP 7.4

There is also a LEPP (Nginx + PostgreSQL + PHP) Docker stack available on this repo

...and a LAMP (Apache + MariaDB + PHP) Docker stack available on this repo

• Install Docker

• Export env variable WWW_DOCUMENT_ROOT to point to your project root directory:

export WWW_DOCUMENT_ROOT="/var/www/html"

• Export env variable MYSQL_ROOT_PASSWORD for defining your MySQL root password:

export MYSQL_ROOT_PASSWORD="root"

WARNING! The root password variable will only be used when creating a database, it won't change the root password of an existing database. And databases are persistent in a volume, even if the image is destroyed and recreated.

• Start Docker compose:

docker-compose up -d

• Access the website at document root on the URL http://localhost:8080/ or http://127.0.0.1:8080/ (both work).

Ports are ignored for connections between containers, so use 3306 (default), and the host name is the mariadb container name. So, i.e.:

try {
    $db = new PDO('mysql:host=mariadb;dbname=my_db_name', 'root', 'root');
}
catch(Exception $e) {
    die('Error: '.$e->getMessage());
}
