使用构建好的 Docker 镜像来搭建 Laravel Sail 开发环境，解决 Laravel Sail 镜像构建失败的问题

@lun1bz 这倒是，哈哈。

端口配反了，前面是容器映射到外部的端口，后面是容器内部端口，所以应该是${APP_PORT:-8088}:80，其中，APP_PORT可以在环境变量里面配置，如果环境变量里面没配置，则将8088映射出去。mysql 那里同理。

wsl2 运行的 Ubuntu 跟 Docker 里面运行的互不干预。构建镜像失败大部分原因都是国内的网络问题，实在难以构建成功，你就按我这个教程来，下载我构建好的镜像到本地然后用docker-compose编排就可以了。还有检查一下你的 sources.list 文件，要选择 Ubuntu 21 的加速地址，教程里面有说明。

给镜像重命名就可以了，这个怪我当时打包用的镜像ID，运行tag命令重命名镜像：

docker tag 5357091b6f9e sail-7.4/app:latest

命令解析：

docker tag IMAGE_ID REPOSITORY:TAG

用 docker-compose 编排容器的时候注意镜像名称要对应 REPOSITORY

修改了镜像名称和docker-compose.yml,执行vendor/bin/sail up

其实就是 php artisan serve, 可以自学一下shell 编程，然后看一下 sail 的实现，你就全懂了。
