我有一个 cronJob，它以某个时间间隔运行以从远程服务器下载图像。我有alpine-php:7.2-fpm泊坞窗图像。它适用于某些 URL。但它在某些 URL 上失败了。

这是 CURL 的代码

$fp = fopen($fileNameWithPath, 'w');

$ch = curl_init();
curl_setopt_array($ch, array(
        CURLOPT_URL => $url,
        CURLOPT_FILE => $fp,
        CURLOPT_ENCODING => "",
        CURLOPT_MAXREDIRS => 10,
        CURLOPT_FOLLOWLOCATION => true,
        CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
        CURLOPT_CUSTOMREQUEST => "GET",
        CURLOPT_CONNECTTIMEOUT => 90,
        CURLOPT_TIMEOUT => 180,
        CURLOPT_SSL_VERIFYHOST => 0,
        CURLOPT_SSL_VERIFYPEER => 0,
        CURLOPT_VERBOSE => 1
));        
$result = curl_exec($ch);
$statusCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
fclose($fp);

我启用了详细，Kubernetes pods 中的日志给出了以下输出

如果我在本地从 docker-image 运行此代码，它工作正常。
