Failed to instantiate \ Aws \ Ec2 \ Ec2Client

Trying to instantiate ec2client wrt

$ec2Client = \Aws\Ec2\Ec2Client::factory(array(
    'profile' => 'default',
    'region'  => 'us-west-2',
    'version' => '2014-10-01'
));

but with an error

Uncaught exception 'Aws\Common\Exception\CredentialsException' with message 'Could not load credentials.'

I have:

cat ~/.aws/credentials 

[default]
aws_access_key_id = xxxxxxxxxxx
aws_secret_access_key = xxxxxxxxxxx

I am using aws-sdk via composer "aws/aws-sdk-php": "3.*@dev"

.

Edit 1): I am trying to do this on my local development machine.

Edit 2): I've tried this:

 use Aws\Common\Credentials\InstanceProfileProvider;
    $profile= new InstanceProfileProvider(['profile'=>'default']);
    $ec2Client = \Aws\Ec2\Ec2Client::factory(array(
        'region'  => 'us-west-2',
        'version' =>'2014-10-01',
        'credentials' => $profile
    ));

This gives me another error:

'Error retrieving credentials from the instance profile metadata server. When you are not running inside of Amazon EC2, you must provide your AWS Access Key ID and Secret Access Key in the "key" and "secret" options when creating a client or provide an instantiated Aws\Common\Credentials\CredentialsInterface object. (cURL error 28: Connection timed out after 1000 milliseconds)' in .. /InstanceProfileProvider.php:9 ..

This gives the impression that credential profiles are only when the application is launched from an AWS cloud instance! Which makes the idea of profiles useless (where intended for a developer environment)

Edit 3)

After debugging this file, it appears that the sdk with credential profiles is broken or not as expected. Both credential profiles

and environment variable

both depend on environment variables. If environment variables are disabled, they will fail.

Possible work around:

a) Include environment variables

b) Set HOME evn variable

putenv('HOME=/Users/yourname');
$ec2Client = \Aws\Ec2\Ec2Client::factory(array(
'region'  => 'us-west-2',
'version' => '2014-10-01'
));

Profile init()

the function has a filename parameter, but there is no way to skip the Credentails profile path other than HOME env

variable

Aws\Common\Credentails\Profiler->init()
public static function ini($profile = null, $filename = null){
...
}

Again, if you can't read the file /Users/yourname/.aws/credentials

, you need to tweak it a bit

chmod 644 /Users/yourname/.aws/credentials

+3

php aws-sdk

You should place the file .aws/credentials

at the root of your web service, not the root of your ssh user

You have to place the .aws / credentials file in your configuration in the home directory of the web service.

Put this in some PHP file of your website

echo getenv('HOME');

then in that directory:

mkdir .aws
touch credentials
nano credentials

And there you need to insert the content (no need for quotes in the keys):

[default]
aws_access_key_id     = xxxxxxxxxxx
aws_secret_access_key = xxxxxxxxxxx

And it should be!

Edit: As sahunzai says in the comment (thanks!), Echo getenv ("HOME") can sometimes return null, if it does, he suggests this solution: "However, from the command line php -i | grep HOME gives me the correct home directory user "

So keep that in mind.
