    --admin \
    --caps="users=read,write;usage=read,write;buckets=read,write;metadata=read,write;zone=read,write" \
    --access-key="<redacted>" \
    --secret="<redacted>"

Usage

Admin Client

use LBausch\CephRadosgwAdmin\Client;

require 'vendor/autoload.php';

$client = Client::make('http://gateway:8080', 'access key', 'secret key');

$response = $client->bucket()->list();

print_r($response->get());

/*
Array
(
    [0] => mybucket
)
*/

Handling Exceptions

Upon failed requests the exception LBausch\CephRadosgwAdmin\ApiException is thrown.

use LBausch\CephRadosgwAdmin\ApiException;
use LBausch\CephRadosgwAdmin\Client;

require 'vendor/autoload.php';

$client = Client::make('http://gateway:8080', 'access key', 'secret key');

try {
    $client->user()->remove('non existent user');
} catch (ApiException $exception) {
    // Exception handling
}

S3 Client

use LBausch\CephRadosgwAdmin\Client;

require 'vendor/autoload.php';

$client = Client::make('http://gateway:8080', 'access key', 'secret key');

$s3client = $client->getS3Client();

// Use different credentials
// $s3client = $client->getS3Client('different access key', 'different secret key');

// Pass arbitrary options to S3 client
// $s3client = $client->getS3Client('different access key', 'different secret key', [
//     'http' => [
//         'verify' => false,
//     ],
// ]);

// Create a bucket
$s3client->createBucket([
    'Bucket' => 'mybucket',
]);

// List all buckets
$buckets = $s3client->listBuckets();

foreach ($buckets['Buckets'] as $bucket) {
    echo $bucket['Name'].PHP_EOL; // mybucket
}

// Put an object in the bucket
$s3client->putObject([
    'Bucket' => 'mybucket',
    'SourceFile' => 'foobar.png',
    'Key' => 'foobar.png',
]);

Custom Configuration

Many settings may be overriden if needed. See LBausch\CephRadosgwAdmin\Config::defaults() for a list of configurable options.

use LBausch\CephRadosgwAdmin\Client;
use LBausch\CephRadosgwAdmin\Config;

require 'vendor/autoload.php';

$config = Config::make([
    // Set a custom admin path
    'adminPath' => 'mgt/',
]);

// Override settings after instantiation, e.g. specify a timeout for requests
$config->set('httpClientConfig', [
    'timeout' => 10,
]);

$client = Client::make('http://gateway:8080', 'access key', 'secret key', $config);
