Aws PHP Sdk 3: S3::putObject(): AWS HTTP error: cURL error 6: Couldn't resolve host 's3.Ireland.amazonaws.com'

Question

I'm trying to upload an image to an S3 bucket using the version 3 of the SDK, but I receive the following error:

Error executing "PutObject" on "https://s3.Ireland.amazonaws.com/my-bucket-name/testFile.jpg"; AWS HTTP error: cURL error 6: Couldn't resolve host 's3.Ireland.amazonaws.com' (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)

This is the first time I try to do this, so I'm not much confident.

Uploading a file through the AWS interface, its URL is something like https://s3-eu-west-1.amazonaws.com/my-bucket-name/testFileThroughWeb.jpg. So, it seems to be different from the one created by the AWS SDK to PUT the file (that is https://s3.Ireland.amazonaws.com/my-bucket-name/testFile.jpg)

Another thing I'd like to point out is the version I pass to the constructor of S3Client. Its instance is created passing to it the value stable for the key version while in the bucket policy I use version: "2012-10-17".

This is the configuration of the bucket policy:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "AddPerm",
            "Effect": "Allow",
            "Principal": {
                "AWS": "*"
            },
            "Action": "s3:*",
            "Resource": "arn:aws:s3:::my-bucket-name/*"
        }
    ]
}

To save the image in the bucket, I use this code:

public function testS3Action()
{
    $fileToUpload = 'http://example.com/an/image.jpg';

    // Get the remote file extension
    $remoteImageExtension = explode('.', $fileToUpload);
    $remoteImageExtension = array_pop($remoteImageExtension);
    $fs = new Symfony\Component\Filesystem\Filesystem();
    $tempImage = tempnam(sys_get_temp_dir(), 'image.') . '.' . $remoteImageExtension;

    /**
     * From the Symfony container
     * @var GuzzleHttp\Client $client
     */
    $client = $this->get('guzzle.client');

    // Get and save file
    $client->get($fileToUpload, ['save_to' => $tempImage]);

    $tempImage = new Symfony\Component\HttpFoundation\File\File($tempImage);

    /**
     * From the Symfony container
     * @var Aws\S3\S3Client $s3
     */
    $s3 = $this->get('shq.amazon.s3');

    $params = [
        'Bucket' => $this->getParameter('amazon.s3.bucket'),
        'Key'    => 'testFile.jpg',
        'Body'   => $tempImage
    ];

    $result = $s3->putObject($params);

    return $result;
}

Which could be the cause of the error I'm getting? Why the host https://s3.Ireland.amazonaws.com guessed by the S3Client isn't correct?

The SDK shouldn't be "guessing" that value, because it's definitely invalid. There's no such endpoint as s3.Ireland.... You don't have something, somewhere, in your configuration or code where "Ireland" appears? — Michael - sqlbot
I set it for the region parameter. When I instantiate the S3 client I pass it the value "Ireland" as region param. — Aerendir

There is no such AWS region as "Ireland". The valid regions for S3 are listed on Amazon's web site; the one you're probably trying to use here is EU (Ireland), which would be represented in a region parameter as eu-west-1.
