我想将 Drupal Docker 容器与 mysql 容器连接起来，但它不起作用

Question

I started to learn Docker and wanted to connect a drupal-container with a mysql-database through docker-compose. It runs (also in the same Network), but whenever I try to login the database-variables in the drupal-browser-window, it doesn't find any connection to a database. Any Ideas?

docker-compose-file:

version: '3.3'

services:
    db-drupal:
        image: mysql:latest
        environment:
            - MYSQL_DATABASE=drupal
            - MYSQL_USER=user
            - MYSQL_PASSWORD=password
            - MYSQL_ROOT_PASSWORD=password
        volumes:
            - Mysql:/var/lib/mysql
        restart: always
    drupal:
        image: drupal:latest
        ports:
            - 80:80
        volumes:
            - Drupal_modules:/var/www/html/modules
            - Drupal_profiles:/var/www/html/profiles
            - Drupal_sites:/var/www/html/sites
            - Drupal_themes:/var/www/html/themes
        depends_on:
            - db-drupal
        links:
            - db-drupal
        restart: always
    
volumes:
    Drupal_modules:
    Drupal_profiles:
    Drupal_sites:
    Drupal_themes:
    Mysql:

here is the error that shows up

Thanks in advance for any help.

您的示例 docker-compose 文件有效，根据使用 MySQL 作为数据库的官方 Drupal 映像中的说明，我已经对其进行了测试，如果您将db-drupal作为数据库主机（而不是本地主机），它可以正常工作。
