Laravel :在docker容器中运行Mysql PHP迁移

Question

我目前有一个龙舌兰帆项目，意思是一个码头集装箱分开在不同的环境。

我刚刚在/database/迁移下创建了一个迁移，以便为电子邮件表单创建一个App。

Hoewever，我无法在我的主docker容器中运行php迁移。

我收到以下错误消息：

照明\数据库\QueryException

SQLSTATEHY000未知数据库“laravel”(SQL: select * from information_schema.tables，其中table_schema =laravel和table_name =迁移，table_type =‘基表’)

在vendor/laravel/framework/src/Illuminate/Database/Connection.php:692 688▕//如果试图运行查询时出现异常，我们将格式化>错误689▕//消息以包含与▕的绑定，这将使此异常对开发人员更有帮助，而不仅仅是数据库的错误。(异常$e) {➜692▕抛出新QueryException( 693▕$query，$this->prepareBindings($bindings)，$e 694▕)；695▕} 696▕}

·数据库名称似乎不正确:您使用的是默认的数据库名laravel。>此数据库不存在。

编辑.env文件并在DB_DATABASE键中使用正确的数据库名称。https://laravel.com/docs/master/database#configuration

我在.env中有正确的主机url ($ docker检查-f -f )，将其替换为mysql-docker容器名导致了同样的问题。

为了正确运行迁移，我需要编辑什么？

对于任何遇到同样问题的人：

我不得不把数据库名"laravel“改为"mysql”！

但是，它现在起作用了！

DB_CONNECTION=mysql
DB_HOST=vs-webpage-mysql-1
DB_PORT=3306
DB_DATABASE=mysql
DB_USERNAME=root
DB_PASSWORD=
