【问题描述】：

我遇到了laravel sail 的问题，碰巧我刚刚克隆了存储库并且它没有改变，docker-compose.yml 完全完好无损，但是，在执行 ./vendor/bin/sail up 之后，我启动了容器，当我尝试进行迁移会引发以下错误

SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: 名称解析暂时失败（SQL: SHOW FULL TABLES WHERE table_type = 'BASE TABLE'）

Docker-compose.yml

【问题讨论】：

DB_HOST=mysql 这是一个有效的主机名吗？

嗯...这是容器的名称，我认为这是有效的。我尝试使用其他主机，但无法正常工作

使用sail时DB HOST是正确的。我也遇到了这个 redis 问题，但它似乎不会影响我的应用程序，只是在错误日志中乱扔垃圾。我仍然可以使用 redis。

【参考方案1】：

你确定你在容器里吗？ 如果您尝试在容器外运行命令，则可以运行 docker exec -it <container_id> php artisan migrate 或sail shell，然后运行你的命令
