从PHP脚本登录Docker Hub [英] Login to Docker Hub from PHP script

问题描述

作为CICD流程的一部分，我正在尝试从PHP脚本登录并推送Docker映像。这是代码：

I am trying to login and push Docker images from a PHP script as part of our CICD process. Here is the code:

<?php

include '../php/database.php';

$duser = 'username';
$dpass = 'password';
$dmail = 'email';

$tag = 'from system';

function tagImage($tag) {
    $getImageID = "SELECT `imageID` FROM `docker_images` WHERE `tag` = :tag ";
    $params = array(':tag' => $tag);
    $results = dataQuery($getImageID, $params);
    if(!empty($results)) {
        $image = $results[0]['imageID'];
        global $repo = $results[0]['repo']; // I know this is a bad idea, will change it when all else is working
        $last = system("sudo docker tag -f $image $repo 2>&1", $retval);
    }
    return $retval;
}

$tagStatus = tagImage($tag);

if(0 == $tagStatus) {
    echo '<pre>';

    $login = system("sudo docker login --username=$duser", $retval);
    var_dump($login);
    var_dump($retval);
    // push it real good
    $last = system("sudo docker push $repo 2>&1", $retval1);
    var_dump($last);
    var_dump($retval1);
}
?>

这将返回以下内容：

string(0) ""
int(1)
The push refers to a repository [app/ap-name] (len: 1)
21d623eb89a9: Image push failed

Please login prior to push:
Username: EOF
string(13) "Username: EOF"
int(1)

推送失败，因为登录无法通过PHP脚本进行，但是，当我从命令行登录时，登录是成功的。

The push is failing because the login is not working from the PHP script, however, when I login from the command line the login is successful.

我在做什么错？我可以像这样用PHP登录Docker Hub吗？还是应该使用不同的技术？

What am I doing wrong? Can I login to Docker Hub with PHP like this? Or should the technique be different?

编辑：：PHP脚本将通过AJAX进行调用，从而有效地像运行脚本一样运行从浏览器。我正在通过浏览器运行它以进行测试。

The PHP script will be called via AJAX, effectively making it run as if it were being run from the browser. I am running it from the browser for testing purposes.

推荐答案

登录名需要所有凭据，包括与之关联的密码和电子邮件地址Docker hub仓库：

The login requires all of the credentials including password and email address associated with the Docker hub repo:

$login = system("sudo docker login --username $duser --password $dpass --email $dmail 2>&1", $retval);
var_dump($login);
var_dump($retval);

使用此语法将返回以下（预期值）：

Using this syntax returns the following (expected):

WARNING: login credentials saved in /root/.dockercfg.
Login Succeeded
string(15) "Login Succeeded"
int(0)

过去指向 push 的位置正常工作，并且不返回任何错误。

Past that point the push works properly and returns no errors.
