使用Docker部署laravel项目时得到mysql错误

我想用像远程服务器一样的testing来testing我的laravel项目。 所以我尝试使用Docker（从来不知道）。 我安装了docker，并按照项目中的说明使用docker进行部署。 build立

将.env.example文件复制到.env，docker-compose.yml.example到docker-compose.yml

修改.envconfiguration文件（可选）。 如果修改.env文件中的mysql，mongo，redisconfiguration，请记得修改docker-compose.yml文件中的configuration。 安装或运行Docker

docker-compose up -d 

// 停止

 docker-compose stop 

chmodcaching文件夹

 chmod -R 777 storage chmod -R 777 bootstrap/cache 

部署

 sh deploy.sh 

运行sh doploy.sh我得到这个错误：

  [Illuminate\Database\QueryException] SQLSTATE[HY000] [2002] No such file or directory (SQL: select * from information_schema.tables where table_schema = awesome_teacher and table_name = migrations) [Doctrine\DBAL\Driver\PDOException] SQLSTATE[HY000] [2002] No such file or directory [PDOException] SQLSTATE[HY000] [2002] No such file or directory [Illuminate\Database\QueryException] SQLSTATE[HY000] [2002] No such file or directory (SQL: select * from information_schema.tables w here table_schema = homestead_test and table_name = migrations) [Doctrine\DBAL\Driver\PDOException] SQLSTATE[HY000] [2002] No such file or directory [PDOException] SQLSTATE[HY000] [2002] No such file or directory 

文件“docker-compose.yml”：

你有一个简单的laravel应用程序相当复杂的设置。 问题是你的laravel应用程序试图连接到它自己的容器中的MySQL服务器实例。

将DB_HOST=localhost更改为DB_HOST=mysql ，而不是连接到mysql容器。
