如何用码头架设黑豹履带

Question

Dockerfile

# https://github.com/symfony/panther#docker-integration
FROM php:latest

RUN apt-get update && apt-get install -y libzip-dev zlib1g-dev chromium && docker-php-ext-install zip
ENV PANTHER_NO_SANDBOX 1

RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

docker-compose.yml

version: "3"
services:
  crawler:
    build: .
    working_dir: /usr/src
    volumes:
      - .:/usr/src
    command: /bin/sh -c "/usr/local/bin/composer install && php index.php"

composer.json

{
    "require": {
        "symfony/panther": "^0.6.0"
    }
}

index.php

<?php

// https://github.com/symfony/panther#basic-usage
require __DIR__.'/vendor/autoload.php'; // Composer's autoloader

$client = \Symfony\Component\Panther\Client::createChromeClient();
$client->request('GET', 'https://api-platform.com'); // Yes, this website is 100% written in JavaScript
$client->clickLink('Support');

// Wait for an element to be rendered
$crawler = $client->waitFor('.support');

echo $crawler->filter('.support')->text();
$client->takeScreenshot('screen.png'); // Yeah, screenshot!

所有文件都在同一个位置。我运行docker-compose build && docker-compose up并得到以下错误：crawler_1 | Fatal error: Uncaught RuntimeException: Could not start chrome (or it crashed) after 30 seconds. in /usr/src/vendor/symfony/panther/src/ProcessManager/WebServerReadinessProbeTrait.php:51

这与https://github.com/symfony/panther/issues/200类似，但是在我的例子中，我不使用黑豹进行测试，而是只使用它进行测试，而且我真的不知道如何解决这个问题。我想我的问题可能与无效的码头/码头组合文件有关。

我也犯了同样的错误。我的解决方案是安装解压缩，如自述文件中所述：

警告:在*nix系统上，必须安装unzip命令，否则您将遇到类似于RuntimeException: sh: 1: exec: RuntimeException权限被拒绝(或chromedriver_linux64: not )的错误。其根本原因是ZipArchive不保留ZipArchive可执行权限。

最后，重新安装黑豹库。
