Question

我为 elasticsearch 和 mysql 制作了 docker-compose。所有容器都“安全地”安装，但是当我尝试使用管理员登录我的数据库并尝试多次时，我不能，并且出现了一些错误：SQLSTATE[HY000] [2002] Connection refused。我不知道为什么，我试图重新启动我的 docker，但我的 db_container 一直在重新启动 SQLSTATE[HY000] [2002] Host is unreachable。在我的 db_container 不断重新启动之前，我已经尝试使用 docker exec -it db_container_name bash 手动创建数据库，但仍然出现相同的错误，我的意思是无法连接。

问题：

MySQL 容器不断重启，我无法通过管理员连接到它

我的 .env：

DB_MASTER_HOST= $DB_MASTER_HOST
DB_CONNECTION=mysql
DB_MASTER_USERNAME= mysql
DB_MASTER_PASSWORD= mysql
DB_MASTER_NAME= horde
DB_MASTER_PORT= 3306

我的 docker-composer.yml：
