PHP扩展不适用于docker-compose中的composer容器 [英] PHP extension unavailable to composer container in docker-compose

问题描述

我使用docker-compose，在一个项目中有多个容器:Nginx，PHP，Composer和nginx.除了一件事，所有方法都运行良好:作曲家不工作.我正在尝试安装使用GD扩展名的composer项目，该扩展名安装在PHP中(在PHP容器内使用php -m确认).但是，作曲家容器没有看到"此扩展名，并且抱怨它不存在.如何链接这两个?

I use docker-compose and have a number of containers in one project: Nginx, PHP, Composer and nginx. All works well except for one thing: composer does not work. I am trying to install a composer project that uses the GD extension, which is installed in PHP (confirmed using php -m inside the PHP container). However, the composer container does not "see" this extension and complaints it does not exist. How can I link those two?

docker-compose.yml:

推荐答案

您是在 php 服务中安装模块，而不是在 composer 服务中安装模块.

You are installing the modules in your php service, but not in your composer service.

运行composer时，其容器中的php安装未安装这些模块.

When composer runs, the php installation in its container doesn't have those modules installed.

您可以在php容器中安装composer，然后从那里运行它.

You could install composer in your php container, and run it from there.

您只需添加以下内容即可

You could do it by simply adding:

# latest composer
COPY --from=composer:latest /usr/bin/composer /usr/bin/composer

在您的php dockerfile中，紧接 RUN 行之后.

In your php dockerfile, right after your RUN line.

这将需要您完全删除composer容器，并直接在PHP容器中运行composer.

That would require you removing your composer container completely, and run composer directly within the PHP container.

您还可以简单地运行composer并告诉它不要检查平台要求:

You can also simply run composer and tell it not to check for platform requirements:

docker run --rm --interactive --tty \
    --volume $PWD:/var/www/html \
    composer install --ignore-platform-reqs 

或者由于某种原因(如果您有单独的作曲家容器)

or if you have a separate composer container, for some reason:

docker-compose run composer install --ignore-platform-reqs
