dockerfile: `composer install --no-dev 安装 dev-dependencies，然后立即删除它们

Question

我的 docker-compose 设置做了（我认为）一些奇怪的事情。

我正在从这个 composer.json:

安装

{
    "require-dev":  {
        "phpunit/phpunit":"~9.0",
        "squizlabs/php_codesniffer": "~3.0",
        "fzaninotto/faker": "~1.9"
    },
    "require": {
        "doctrine/orm": "2.7.2",
        "haydenpierce/class-finder": "0.4.2"
    },
    "autoload" : {
        "psr-4": {
            "WebApp\": "src/"
         }
    },
    "autoload-dev" : {
        "psr-4": {
            "WebApp\Tests\" : "tests/"
        }
    }
}

我的 dockerfile 看起来像：

FROM php:7.4.4-apache

#Install git
RUN php -v
RUN apt-get update && apt-get install -y git
RUN apt-get install zip unzip
RUN docker-php-ext-install pdo pdo_mysql mysqli

#enable Ubuntu module 'URL rewrite'
RUN a2enmod rewrite

#Install Composer
RUN php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
RUN php composer-setup.php --install-dir=/usr/local/bin/ --filename=composer

#setup database secrets file
COPY db_secret.prod.php /etc/db_secret.prod.php

#Make php error log file
RUN touch /var/log/php-error.log
RUN chmod 755 /var/log/php-error.log

#copy across necessary files
COPY . /var/www/
RUN rm /var/www/db_secret.prod.php

#change root that server runs files from
RUN sed -i 's+/var/www/html+/var/www/src/html+i' /etc/apache2/sites-available/000-default.conf

#Install php testing
RUN cd .. && composer update && composer install --no-dev

#RUN cd .. && vendor/bin/doctrine orm:schema-tool:create

EXPOSE 80

当运行 composer install 我得到：

Step 15/16 : RUN cd .. && composer update && composer install --no-dev

谁能告诉我为什么它会安装然后删除开发包而不是从原始安装中省略它们？

docker文件的容器是php744-apache

Answer 1

很简单：你运行 composer update （这将更新软件包列表，并安装它们），然后你运行 composer install --no-dev.

出于好奇：这仅在更新 Docker 图像时完成。这有什么充分的理由吗？为什么不将图像和图像中的源代码运行ning 分离？
