'mysql: not found'，试图连接 laravel、mysql 和 nginx 容器中的 Z05B6053315A2DA4BEE6B 容器

Question

• Ubuntu 20.04

• Docker 版本 19.03.14

• docker-compose 版本 1.25.0

我试图弄清楚为什么我会收到与 mysql 相关的错误。 我做的步骤：

• 克隆我的 laravel 项目
• docker-compose 构建
• docker-compose 向上 -d
• docker-compose 执行应用程序 php 工匠密钥：生成
• docker-compose 执行应用程序 php 工匠配置：缓存
• docker-compose 执行应用程序 php 工匠迁移

在最后一个我收到以下错误：

Migration table created successfully.
Loading stored database schema: /var/www/database/schema/mysql-schema.dump

   Symfony\Component\Process\Exception\ProcessFailedException 

  The command "mysql  --user="${:LARAVEL_LOAD_USER}" --password="${:LARAVEL_LOAD_PASSWORD}" --host="${:LARAVEL_LOAD_HOST}" --port="${:LARAVEL_LOAD_PORT}" --database="${:LARAVEL_LOAD_DATABASE}" < "${:LARAVEL_LOAD_PATH}"" failed.

Exit Code: 127(Command not found)

Working directory: /var/www

Output:

Error Output:

您在尝试执行 mysql 命令的容器中没有 mysql 客户端。 通过 Dockerfile 添加 mysql。

RUN apt-get update && apt-get install -y mysql-client && rm -rf /var/lib/apt
