AWS CloudFormation

This guide focuses on the AWS SDK for PHP client for AWS CloudFormation. This guide assumes that you have

already downloaded and installed the AWS SDK for PHP. See Installation for more information on getting started.

Creating a client

First you need to create a client object using one of the following techniques.

Factory method

The easiest way to get up and running quickly is to use the

Aws\CloudFormation\CloudFormationClient::factory() method and provide your credentials (key and

secret).

A region parameter is also required and must be set to one of the following values: us-east-1,

ap-northeast-1, sa-east-1, ap-southeast-1, ap-southeast-2, us-west-2, us-gov-west-1,

us-west-1, cn-north-1, eu-west-1

use Aws\CloudFormation\CloudFormationClient;

$client = CloudFormationClient::factory(array(

'key' => '<aws access key>',

'secret' => '<aws secret key>',

'region' => '<region name>'

));

You can provide your access keys like in the preceding example, or you can choose to omit them if you are using

AWS Identity and Access Management (IAM) roles for EC2 instances or credentials sourced from the

AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables.

Service builder

A more robust way to connect to AWS CloudFormation is through the service builder. This allows you to specify

credentials and other configuration settings in a configuration file. These settings can then be shared across all

clients so that you only have to specify your settings once.

use Aws\Common\Aws;

// Create a service builder using a configuration file

$aws = Aws::factory('/path/to/my_config.json');

// Get the client from the builder by namespace

$client = $aws->get('CloudFormation');
