Net::Amazon::EC2(3) User Contributed Perl Documentation Net::Amazon::EC2(3)

Net::Amazon::EC2 - Perl interface to the Amazon Elastic Compute Cloud (EC2) environment.

EC2 Query API version: '2014-06-15'

 use Net::Amazon::EC2;
 my $ec2 = Net::Amazon::EC2->new(
        AWSAccessKeyId    => 'PUBLIC_KEY_HERE', 
        SecretAccessKey   => 'SECRET_KEY_HERE',
        signature_version => 4,
 );
 # Start 1 new instance from AMI: ami-XXXXXXXX
 my $instance = $ec2->run_instances(ImageId => 'ami-XXXXXXXX', MinCount => 1, MaxCount => 1);
 my $running_instances = $ec2->describe_instances;
 foreach my $reservation (@$running_instances) {
        foreach my $instance ($reservation->instances_set) {
                print $instance->instance_id . "\n";
        }
 }
 my $instance_id = $instance->instances_set->[0]->instance_id;
 print "$instance_id\n";
 # Terminate instance
 my $result = $ec2->terminate_instances(InstanceId => $instance_id);

If an error occurs while communicating with EC2, these methods will throw a Net::Amazon::EC2::Errors exception.

This module is a Perl interface to Amazon's Elastic Compute Cloud. It uses the Query API to communicate with Amazon's Web Services framework.

This is the constructor, it will return you a Net::Amazon::EC2 object to work with. It takes these parameters:

Your AWS access key. For information on IAM roles, see <http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/UsingIAM.html#UsingIAMrolesWithAmazonEC2Instances>
Your secret key, WARNING! don't give this out or someone will be able to use your account and incur charges on your behalf.
When using temporary credentials from STS the Security Token must be passed in along with the temporary AWSAccessKeyId and SecretAccessKey. The most common case is when using IAM credentials with the addition of MFA (multi-factor authentication). See <http://docs.aws.amazon.com/STS/latest/UsingSTS/Welcome.html>
The region to run the API requests through. Defaults to us-east-1.
If set to a true value, the base_url will use https:// instead of http://. Setting base_url explicitly will override this. Defaults to true as of 0.22.
A flag to turn on debugging. Among other useful things, it will make the failing api calls print a stack trace. It is turned off by default.
Previously, Net::Amazon::EC2 would return a Net::Amazon::EC2::Errors object when it encountered an error condition. As of 0.19, this object is thrown as an exception using croak or confess depending on if the debug flag is set.

If you want/need the old behavior, set this attribute to a true value.

allocate_address()

Acquires an elastic IP address which can be associated with an EC2-classic instance to create a movable static IP. Takes no arguments.

Returns the IP address obtained.

allocate_vpc_address()

Acquires an elastic IP address which can be associated with a VPC instance to create a movable static IP. Takes no arguments.

Returns the allocationId of the allocated address.

Associates an elastic IP address with an instance. It takes the following arguments:

The instance id you wish to associate the IP address with
The IP address. Used for allocating addresses to EC2-classic instances.
The allocation ID. Used for allocating address to VPC instances.

Returns true if the association succeeded.

Attach a volume to an instance.

The volume id you wish to attach.
The instance id you wish to attach the volume to.

Creates an AMI that uses an Amazon EBS root device from a "running" or "stopped" instance.

AMIs that use an Amazon EBS root device boot faster than AMIs that use instance stores. They can be up to 1 TiB in size, use storage that persists on instance failure, and can be stopped and started.

The name of the AMI that was provided during image creation.

Note that the image name has the following constraints:

3-128 alphanumeric characters, parenthesis, commas, slashes, dashes, or underscores.

The description of the AMI that was provided during image creation.
By default this property is set to false, which means Amazon EC2 attempts to cleanly shut down the instance before image creation and reboots the instance afterwards. When set to true, Amazon EC2 does not shut down the instance before creating the image. When this option is used, file system integrity on the created image cannot be guaranteed.
Array ref of the device names exposed to the instance.

You can specify device names as '<device>=<block_device>' similar to ec2-create-image command. (<http://docs.aws.amazon.com/AWSEC2/latest/CommandLineReference/ApiReference-cmd-CreateImage.html>)

Set AWS_ACCESS_KEY_ID and SECRET_ACCESS_KEY environment variables to run the live tests. Note: because the live tests start an instance (and kill it) in both the tests and backwards compat tests there will be 2 hours of machine instance usage charges (since there are 2 instances started) which as of February 1st, 2010 costs a total of $0.17 USD

Important note about the windows-only methods. These have not been well tested as I do not run windows-based instances, so exercise caution in using these.

Please report any bugs or feature requests to "bug-net-amazon-ec2 at rt.cpan.org", or through the web interface at <http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Net-Amazon-EC2>. I will be notified, and then you'll automatically be notified of progress on your bug as I make changes.
