Aws Php SDk - Create Cloudfront distribution using hard-coded credentials - php

Question

I'm trying to create a cloudfront distribution while doing the authentication via hardcoded credentials.
However i receive this error when i run my code
Fatal error: Uncaught Aws\Exception\CredentialsException: Cannot read credentials from /.aws/credentials
It seems that the aws sdk is trying to authentificate using the second method listed here ( https://docs.aws.amazon.com/sdk-for-php/v3/developer-guide/guide_credentials.html ) - the one when you put the credentials in ./aws folder
Here is my code (taken from aws documentation ) - Any idea why this is not working ?
public function create_cloudfront_client(){
$region='us-east-1';
$client = new Aws\CloudFront\CloudFrontClient([
'profile' => 'default',
'version' => 'latest',
'region' => 'us-east-1',
'debug' => true,
'credentials' =>[
'key' => $this->aws_key,
'secret' => $this->aws_secret,
],
]);
$originName = 'cloudfrontme';
$s3BucketURL = 'https://s3.amazonaws.com/cloudfrontme';
$callerReference = 'uniquestring99';
$comment = 'Created by AWS SDK for PHP';
$cacheBehavior = [
'AllowedMethods' => [
'CachedMethods' => [
'Items' => ['HEAD', 'GET'],
'Quantity' => 2,
],
'Items' => ['HEAD', 'GET'],
'Quantity' => 2,
],
'Compress' => false,
'DefaultTTL' => 0,
'FieldLevelEncryptionId' => '',
'ForwardedValues' => [
'Cookies' => [
'Forward' => 'none',
],
'Headers' => [
'Quantity' => 0,
],
'QueryString' => false,
'QueryStringCacheKeys' => [
'Quantity' => 0,
],
],
'LambdaFunctionAssociations' => ['Quantity' => 0],
'MaxTTL' => 0,
'MinTTL' => 0,
'SmoothStreaming' => false,
'TargetOriginId' => $originName,
'TrustedSigners' => [
'Enabled' => false,
'Quantity' => 0,
],
'ViewerProtocolPolicy' => 'allow-all',
];
$enabled = false;
$origin = [
'Items' => [
[
'DomainName' => $s3BucketURL,
'Id' => $originName,
'OriginPath' => '',
'CustomHeaders' => ['Quantity' => 0],
'S3OriginConfig' => ['OriginAccessIdentity' => ''],
],
],
'Quantity' => 1,
];
$distribution = [
'CallerReference' => $callerReference,
'Comment' => $comment,
'DefaultCacheBehavior' => $cacheBehavior,
'Enabled' => $enabled,
'Origins' => $origin,
];
try {
$result = $client->createDistribution([
'DistributionConfig' => $distribution, //REQUIRED
]);
var_dump($result);
} catch (AwsException $e) {
// output error message if fails
echo $e->getMessage();
echo "\n";
}
}

Answer 1

The solution was to create the cloudfront client like this
$client = Aws\CloudFront\CloudFrontClient::factory(array(
'region' => $bucket_region,
'version' => 'latest',
'credentials' => [
'key' => $this->aws_key,
'secret' => $this->aws_secret,
]
));
However i don't understand why this version works while the one below (from aws docs ) does not. Can anyone explain this ?
Thanks
$client = new Aws\CloudFront\CloudFrontClient([
'version' => 'latest',
'region' => $bucket_region,
'debug' => true,
'credentials' =>[
'key' => $this->aws_key,
'secret' => $this->aws_secret,
],
]);
