Calling create is the only way to obtain the private key programmatically.You can always access

your private key through the AWS Management Console.

Before logging onto an Amazon EC2 instance, you must create the instance and ensure that it is running.

For information about how to run an Amazon EC2 instance, see Run an Amazon EC2 Instance (p. 18).

For information about how to use your key pair to connect to your Amazon EC2 instance, see Connect

to Your Amazon EC2 Instance (p. 18).

Run an Amazon EC2 Instance

Note

This documentation is for the AWS SDK for Ruby version 1, which is a legacy version. For the

most recent version of the SDK for Ruby, see AWS SDK for Ruby - Version 2.

Before running an Amazon EC2 instance, ensure that you have created a security group and a key pair

for your instance. For information about creating a key pair, see Create a Key Pair (p. 17). For information

about creating a security group, see Create an Amazon EC2 Security Group (p. 16).

Use the InstanceCollection.create method to run an Amazon EC2 instance. Specify the Amazon Machine

Image (AMI), the instance type, the maximum number of instance to run, the names of a security group

and key pair you created, as follows:

instance = ec2.instances.create(

:image_id => 'ami-11d68a54',

:instance_type => 'm1.small',

:count => 1,

:security_groups => 'YOUR_SECURITY_GROUP_NAME',

:key_pair => ec2.key_pairs['YOUR_KEY_PAIR_NAME'])

You must specify a public or privately-provided AMI. A large selection of Amazon-provided public AMIs

is available for you to use. For a list of public AMIs provided by Amazon, go to Amazon Machine Images.

Ensure that the specified image ID exists in the region in which your client was created.

The instance type must match the AMI you want to run. For 64-bit architecture, you cannot specify an

instance type of m1.small. For more information on instance types, go to Instance Families and Types.

You must specify a maximum number of instances to launch. If the specified number of instances is

greater than the number of instances you are authorized to launch, no instances are launched. The

specified number of maximum instances must be no greater than the maximum number allowed for your

account; by default, this is 20. If fewer instances are available than the maximum number specified, the

largest possible number of images are launched.

Ensure that the specified key name and security group exists for the region in which your client was

created.

After you have created your Amazon EC2 instance, you can log onto the AWS Management Console to

check the status of the instance.

Once your Amazon EC2 instance is running, you can remotely connect to it using your key pair. For

information about connecting to your instance, see Connect to Your Amazon EC2 Instance (p. 18).
