Question

我想使用php 7.2.10-fpm，nginx和mysql 5.7设置一个小型docker环境，以便在其中运行Laravel 5.7。不幸的是，当尝试从我的应用程序服务连接到mysql（尝试运行docker-composer exec app php artisan migrate）时，出现以下错误：

In Connector.php
SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name or service not known
PDO::__construct(): php_network_getaddresses: getaddrinfo failed: Name or service not known

尝试运行docker-compose exec app mysql -u root -p会返回：错误2002（HY000）：无法通过套接字'/var/run/mysqld/mysqld.sock'（2“无此文件或目录”）连接到本地MySQL服务器

通过docker-compose up --build启动和构建容器不会引发任何错误。它表示mysql正在运行并正在等待连接。我还通过docker system prune --force --volumes删除并重新创建了所有图像。

也许我错过了docker-compose.yml中的某些内容？

    ports:

App.dockerfile：

FROM php:7.2.10-fpm

RUN apt-get update
RUN apt-get install -y libmcrypt-dev
RUN apt-get install -y mysql-client
RUN apt-get install -y libmagickwand-dev --no-install-recommends
RUN pecl install imagick
RUN docker-php-ext-enable imagick
RUN docker-php-ext-install pdo_mysql
RUN pecl install mcrypt-1.0.1
RUN docker-php-ext-enable mcrypt
RUN php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
RUN php -r "if (hash_file('SHA384', 'composer-setup.php') === '93b54496392c062774670ac18b134c3b3a95e5a5e5c8f1a9f115f203b75bf9a129d5daa8ba6a13e2cc8a1da0806388a8') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
RUN php composer-setup.php
RUN php -r "unlink('composer-setup.php');"
RUN mv composer.phar /usr/local/bin/composer
RUN apt-get install -y git
RUN apt-get update && apt-get install -y zlib1g-dev
RUN docker-php-ext-install zip

最后是我来自Laravel的.env文件：

DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3306
DB_DATABASE=shop
DB_USERNAME=shop_u
DB_PASSWORD=secret

更新

docker-compose images列出了以下容器：

+-----------------+-------------------+----------------+
|    Container    |    Repository     |    ImageID     |
+-----------------+-------------------+----------------+
| docker_app_1    |  docker_app       |   a94dba376130 |
| docker_mysql_1  |  docker_database  | 563a026a1511   |
| docker_web_1    |  docker_web       |   d9024ab40b73 |
+-----------------+-------------------+----------------+

从ping docker_mysql_1运行docker exec -it docker_app_1 bash会产生bash: ping: command not found。

从ping docker_mysql_1运行docker exec -it docker_web_1 bash很好。
