WSL windows laravel SQLSTATE[HY000] [2002]

Question

I recently started a laravel(8) project on my windows machine using WSL (Ubuntu 20.4) and docker. When reading data from the database I get the error 'SQLSTATE[HY000] [2002]No such file or directory' for DB_HOST=localhost or 'SQLSTATE[HY000] [2002] Connection refused' for DB_HOST=127.0.0.1. However, this problem appears only when I start the whole project using ./vendor/bin/sail up, when I boot the same project using php artisan serve the error does not appear for either DB_HOST configuration.

index function to show what is in DB

public function index()
{
        dd(Customer::all());
}

Customer object

class Customer extends Model
{
    use HasFactory;

    protected $table = 'customers';

    protected $primaryKey = 'id';

}

.env file

APP_NAME=Laravel
APP_ENV=local
APP_KEY=base64:WtHehq3ZteXPe6xEIij2TBblW7Qo3VUd5obTao3Kg4U=
APP_DEBUG=true

SCOUT_DRIVER=meilisearch
MEILISEARCH_HOST=http://meilisearch:7700

I already tried the solution with setting unix_socket to '/Applications/MAMP/tmp/mysql/mysql.sock' and also to the result of show variables like '%sock%'; of the 'socket' entry. I tried setting this value in both the '.env' file and in 'database.php'.

commands

php artisan key:generate
php artisan cache:clear
php artisan route:clear
php artisan config:clear 
php artisan view:clear

also failed me

If you are using docker, you don't have to use any host as localhost, but rather use the service name as the host, for example, if you docker-compose.yaml is like this:

version: '3.9'

services:

  superNiceDb:
    image: mysql:8.0
    command: --default-authentication-plugin=mysql_native_password
    environment:
        MYSQL_DATABASE: 'laravel'
        MYSQL_ROOT_PASSWORD: '123'
    volumes:
      - ./docker/mysql_data:/var/lib/mysql
      - ./docker/mysql:/docker-entrypoint-initdb.d
    ports:
      - ${DB_PORT:-3306}:3306

You have to use DB_HOST=superNiceDb in your .env or wherever you are reading that value from.

This applies to any system, if you are using docker, this is the only way of referring to services, never use localhost.
