【问题描述】：
我正在尝试构建一个包含 PHP 应用程序的 docker 映像。
此应用程序通过 composer.json 安装一些依赖项，并且在 composer 安装后，需要完成一些自定义（例如，必须将一些文件从供应商文件夹复制到其他位置等等）。
所以我将这些步骤写成 bash 命令并放在 composer.json post-install-cmd 部分。
这是我的composer.json（我省略了细节，但结构是一样的）：
{
"name": "MyApp",
"description": "My Service",
"type": "project",
"repositories": {
"a-fancy-library-i-depend-on": {
"type": "package",
"package": {
"name": "a-fancy-library-i-depend-on",
"version": "1.0",
"source": {
"url": "https://github.com/a-fancy-library-i-depend-on",
"type": "git",
"reference": "master"
}
}
},
},
"require": {
"symfony/filesystem": "5.2.6",
"symfony/yaml": "^4.2"
},
"require-dev": {
"a-fancy-library-i-depend-on": "*"
},
"scripts": {
"post-install-cmd": [
"rm -rf ./src/setup",
"cp -r vendor/a-fancy-library-i-depend-on/setup/ ./src/setup",
"mkdir vendor/a-fancy-library-i-depend-on/log"
]
},
"autoload": {
"classmap": [
"src/"
]
},
"config": {
"allow-plugins": {
"a-fancy-library-i-depend-on/composer-module-installer": true
}
}
}
在我的 Dockerfile 中，我包含了一个运行 composer install 的步骤：
FROM php:7.4.20-fpm
RUN apt-get update && apt-get install -y git zlib1g-dev libzip-dev libpng-dev libicu-dev g++ zip unzip
RUN docker-php-ext-install zip gd intl
RUN docker-php-ext-configure intl
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
ADD code /code
WORKDIR /code
RUN composer install
问题是“安装后”脚本没有执行。
镜像构建成功，但安装文件夹为空。
如果我从此图像运行容器并在其上输入 bash
docker container run -ti my-image:local bash
然后我尝试运行
# composer install
瞧！脚本被执行。
这是构建映像命令的 composer install 阶段输出：
Step 10/15 : RUN composer install

如何调试这个问题？
【问题讨论】：
-
我知道脚本没有被执行，因为必须复制的文件不在目标文件夹中。顺便说一句，我发现如果我第二次重复 composer install 脚本会被执行，但在我看来这不是一个非常干净的解决方案......
-
No composer.lock file present- 这不是一个好兆头。你不应该在没有锁定文件的情况下运行composer install。 -
另外，为什么需要在
vendor文件夹中手动新建文件夹？你不应该以任何方式修改这些内容，并且有一个日志文件夹有一个巨大的危险信号 -
我知道这不是一个好习惯，但我正在使用（某种）自定义库，强制这样做（我的意思是在供应商文件夹中写东西）......跨度>
