应该从哪个 Dockerfile 中调用 composer install

Question

我需要调用 composer install 并且不确定从哪个 Dockerfile 调用它 - Dockerfile-apache 或 Dockerfile-php-fpm?

我应该在 Dockerfile-apache（和 PHP CLI 中安装 composer 吗？）并从那里运行安装它？

运行 composer install from Dockerfile-php-fpm 给我这个：Composer could not find a composer.json file in /var/www/html

Docker-php-fpm

# Do we target a specific version? ie. 7.4.25?
FROM php:7.4-fpm

# Need to add zip and other extensions
RUN buildDeps=" \
        libonig-dev \
        libzip-dev \
        libxml2-dev \ 
    " \ 
&& apt-get -y update \
&& apt-get install -y $buildDeps zip libicu-dev \ 
&& docker-php-ext-configure intl \
&& docker-php-ext-install intl mbstring json mysqli opcache pdo pdo_mysql xml \ 
&& apt-get purge -y --auto-remove $buildDeps \
&& rm -r /var/lib/apt/lists/*

        && ln -s /usr/local/bin/composer.phar /usr/local/bin/composer

Docker-apache:

FROM httpd:2.4

#Set our application folder as an environment variable

此 docker-compose 文件支持通过公共卷进行通信。此时我只需要在 Apache 中编译、构建和复制文件。

version: "3.9"
services:
  php-fpm:
    container_name: php-fpm
    build:
      context: .
      dockerfile: Dockerfile-php-fpm
    volumes:
      - mydata:/var/www/html:rw
    networks:
      - backend
    ports:
      - "9000:9000"
  apache:
    container_name: httpd
    build:
      context: .
      dockerfile: Dockerfile-apache
    depends_on:
      - php
    volumes:
      - mydata:/var/www/html:rw
    networks:
      - frontend
      - backend
    ports:
      - "80:80"
      - "443:443"

我不会选择以上任何一种；相反，运行 composer install 在本地复制生成的 vendor 目录作为应用程序的一部分 .

获取依赖项基本上是构建应用程序的一部分，而不是运行宁应用程序的一部分，因此 Composer 不应该甚至不能安装在生产主机或容器上。如果您正在编写一个需要使用 gcc 进行编译的 C 应用程序，您将运行作为较早的步骤，然后将二进制文件复制到容器中； composer install也可以这样处理。

因此，例如，您可能有一个构建脚本（到运行手动，或在 CI 服务器中，如 Jenkins、Github Actions、Azure DevOps 等）通过以下步骤：

从 git 存储库克隆存储库
查看最新标签
运行 composer install
运行一个脚本来缩小 client-side JS
运行docker-composer，复制源码，压缩JS，vendor目录

insideDocker容器中的软件因此只需要能够运行应用程序，不是构建它。
