看起来您缺少几个环境变量。

首先，在您的mysql-server服务中，您仅指定MYSQL_ROOT_PASSWORD。这不会创建您在zabbix-web和zabbix-server服务中使用的用户和密码组合。您还需要指定MYSQL_DATABASE=zabbix、MYSQL_USER=user和MYSQL_PASSWORD=pass。

然后，根据 Zabbix 镜像文档，您需要指定DB_SERVER_HOST=mysql-server以便 Zabbix 知道如何访问链接的 MySQL 服务器。也有，MYSQL_DATABASE但它默认为zabbix我们在 MySQL 服务中指定要创建的内容，因此默认应该有效。
