如何在 php 部署程序中从 .env 而不是 ~/.ssh/config 设置主机详细信息

Question

我正在寻找如何设置主机用户并从 env 传递

这不起作用 - 需要字符串而不是函数

host('51.38.98.87')
    ->stage('production')
    ->user( function(){return getenv('PRODUCTION_USER'); )
    ->pass( function(){return getenv('PRODUCTION_PASS'); )
    ->port(22)

在 Symfony 4 中，我使用 env 并且不希望在 ~/.ssh/config 中设置主机

更新1 ：

<?php
namespace Deployer;
use SymfonyComponentDotenvDotenv;
require 'recipe/symfony.php';
require_once 'vendor/autoload.php';
$dotenv = new Dotenv();
$dotenv->load(__DIR__.'/.env');

然后

DEP 部署生产

获取

dep deploy production

 [Error] Class 'SymfonyComponentDotenvDotenv' not found                                                              

 #0 phar:///usr/local/bin/dep/src/Deployer.php(325): require()                                                          
 #1 [internal function]: DeployerDeployer::Deployer{closure}()                                                        
 #2 phar:///usr/local/bin/dep/src/Deployer.php(326): call_user_func(Object(Closure))                                    
 #3 phar:///usr/local/bin/dep/bin/dep(119): DeployerDeployer::run('6.3.0',

更新 2

composer.json 有 symfony/dotenv

 "require-dev": {
        "doctrine/doctrine-fixtures-bundle": "^3.0",
        "symfony/browser-kit": "^4.0",
        "symfony/css-selector": "^4.0",
        "symfony/debug-pack": "*",
        "symfony/dotenv": "^4.0",
        "symfony/maker-bundle": "^1.0",
        "symfony/phpunit-bridge": "^4.0",
        "symfony/profiler-pack": "*",
        "symfony/web-server-bundle": "^4.0"
    },

但仍然

namespace Deployer;
use SymfonyComponentDotenvDotenv;
require 'vendor/autoload.php';
require 'recipe/symfony.php';

$dotenv = new Dotenv();
$dotenv->load(__DIR__.'/.env');

给我的

Class 'SymfonyComponentDotenvDotenv' not found                                                              

 #0 phar:///usr/local/bin/dep/src/Deployer.php(325): require()                                                          
 #1 [internal function]: DeployerDeployer::Deployer{closure}()

 #5 {main}        

更新 3
我创建测试文件：./测试.php

<?php
use SymfonyComponentDotenvDotenv;
require 'vendor/autoload.php';
(new Dotenv())->load(__DIR__.'/.env');

PHP测试.php工作正常。

从同一位置运行 dep 部署：暂存

给我的

 [Error] Class 'SymfonyComponentDotenvDotenv' not found                                                              

 #0 phar:///usr/local/bin/dep/src/Deployer.php(325): require()     

我的部署.php文件

<?php
namespace Deployer;
use SymfonyComponentDotenvDotenv;
require 'vendor/autoload.php';
require 'recipe/symfony.php';
(new Dotenv())->load(__DIR__.'/.env');

部署程序是全局安装的

whereis dep
dep: /usr/local/bin/dep

Answer 1

您是否尝试在 deploy.php 文件中启用 symfony/dotenv？

require_once 'vendor/autoload.php';
$dotenv = new Dotenv();
$dotenv->load(__DIR__.'/.env');

您首先需要安装 dotenv 组件：

composer require --dev symfony/dotenv

如果在仅具有生产依赖项的环境中使用它，请删除 --dev 选项。

我正在使用 .env 文件来生成设置文件，我解决这个问题的方法是向主机添加一个指示 .env 和模板文件的属性：

# hosts.yml
hostname:
  ...
  env_file: .env.stage
  settings_template: somewhere/file.template
# file.template
...
'database' => '{{DB_NAME}}',
...

使用函数加载凭据：

# deploy.php
// Loading of .env files
// add Symfony's dotenv as a requirement: composer global require symfony/dotenv:"^3"
function loadenv() {
    $env_file = get('env_file');
    $environment = file_get_contents($env_file);
    $dotenv = new SymfonyComponentDotenvDotenv();
    $data = $dotenv->parse($environment);
    return $data;
};

最后，创建一个调用 loadenv() 函数的任务，将凭据写入文件并将其上传到服务器：

task('upload:settings', function () {
    if (askConfirmation('Are you sure to generate and upload the settings?')) {
        //Get template
        $template = get('settings_template');
        //Import secrets
        $secrets = loadenv();
        //Prepare replacement variables
        $iterator = new RecursiveIteratorIterator(
            new RecursiveArrayIterator($secrets)
        );
        $replacements = [];
        foreach ($iterator as $key => $value) {
            $keys = [];
            for ($i = $iterator->getDepth(); $i > 0; $i --) {
                $keys[] = $iterator->getSubIterator($i - 1)->key();
            }
            $keys[] = $key;
            $replacements['{{' . implode('.', $keys) . '}}'] = $value;
        }
        //Create settings from template
        $settings = file_get_contents($template);
        $settings = strtr($settings, $replacements);
        $tmpFilename = 'settings.tmp';
        file_put_contents($tmpFilename, $settings);
        upload($tmpFilename, '{{release_path}}/somewhere', ['options'=> ['--inplace']]);
    }
});
