Gitlab registry api

This is a package to use Docker registry from GitLab. I wrote it because I couldn't found an usefull library with fully implementation (read and destroy). To simplify the use, all element returned are objects (and it's pretty cool in your IDE).

Private registry

If you have a private registry, you'll need to create a Personal Access Token in order to access it. This is in your profile, settings and access tokens. If you want to read and delete element, you must check "api" and "read_registry".

Installation

Use Composer to install it, this repo is on Packagist, so something like this should be fine:

{
    "require": {
        "thecodingmachine/gitlab-registry-api": "^1.0"
    }
}

Then do composer install or composer update in the usual way.

To make use of it, load the autoloader:

require_once __DIR__ . '/vendor/autoload.php';

How to it work

With your personnal registry information (domain, token, gorup and project), I use Guzzle 6 to call the registry api. So in all this package you could catch a Guzzle Exception if there is an error with an api call.

How to use it

I tried to simplify the use as much as possible with object manipulation. But is always possible to get the original array result, with the function getPayload() on Image or Tag.

Get data

There is a getter for each attribut of each element.

Example:

// Create client with access
$client = new Client('https://git.yourdomain.com/', 'myPrivateAccessToken');
// Declare your registry and retrieve a Registry object
$registry = $client->getRegistry('myGroup', 'myProject');
foreach ($registry->getImages() as $image) {
    echo $image->getId();
    foreach ($image->getTags() as $tag) {
        echo $tag->geTotalSize();
    }
}

If your group and project is already concatenated (like your registry comes from GitLab api), you could set it in only the group parameter :

$client = new Client('https://git.yourdomain.com/', 'myPrivateAccessToken');
$registry = $client->getRegistry('myGroup/myProject');
foreach ($registry->getImages() as $image) {
    echo $image->getId();
    foreach ($image->getTags() as $tag) {
        echo $tag->geTotalSize();
    }
}

Pagination

In the tag list, it's possible to add paginate parameter to filter result:

$client = new Client('https://git.yourdomain.com/', 'myPrivateAccessToken');
$registry = $client->getRegistry('myGroup/myProject');
foreach ($registry->getImages() as $image) {
    echo $image->getId();
    // Pagination, get second page with 10 elements
    foreach ($image->getTags(2, 10) as $tag) {
        echo $tag->geTotalSize();
    }
}

Destroy

You could destroy an image or only a tag with a simple method destroy.

Example for image:

$client = new Client('https://git.yourdomain.com/', 'myPrivateAccessToken');
$registry = $client->getRegistry('myGroup/myProject');
foreach ($registry->getImages() as $image) {
    // This return true, false or guzzle exception
    var_dump($image->destroy());
}

Example for tag:

$client = new Client('https://git.yourdomain.com/', 'myPrivateAccessToken');
$registry = $client->getRegistry('myGroup/myProject');
foreach ($registry->getImages() as $image) {
    foreach ($image->getTags() as $tag) {
        // This return true, false or guzzle exception
        var_dump($tag->destroy());
    }
}

Payload

You could retrieve the original array result.
