我正在尝试制作一个 symfony6 php8 nginx 影像

到目前为止运行docker-compose -build我收到错误

#25 3.462   [InvalidArgumentException]      
#25 3.462   Could not find package ext-gd. 

这是我的 Dockerfile

Dockerfile 看起来像来自使用 Caddy 的 Symfony Github 的那个。

要使其与 Symfony 6.0.1 一起使用，请从https://github.com/dunglas/symfony-docker下载最新的 symfony-docker

然后在您的终端视窗中，转到您下载上述项目运行的目录：

SYMFONY_VERSION=6.* docker-compose up --build

这将使用 PHP 8、Caddy 和 Symfony 6.0.1 启动一个极简主义的框架 Symfony 构建

如果你想要网站骨架使用

SKELETON=symfony/website-skeleton SYMFONY_VERSION=6.* docker-compose up --build

uj5u.com热心网友回复：

您是否尝试在 docker 上安装 gd？

docker-php-ext-install gd

我 3 年前遇到过这个问题，docker 上缺少 gd 和其他一些包，我们只是将它们添加到 docker 档案中。
