config_file = File.join(File.dirname(__FILE__), "config.yml")

AWS.config(YAML.load(File.read(config_file)))

2. Create a new EC2 instance, specifying the service endpoint as follows:

ec2 = AWS::EC2.new(:ec2_endpoint => 'ec2.us-west-1.amazonaws.com')

By default, the service endpoint is ec2.us-east-1.amazonaws.com. For a list of Amazon EC2

service endpoints, go to Regions and Endpoints .

Before running an Amazon EC2 instance, you will need to create an Amazon EC2 security group, authorize

security group ingress, and create a key pair to allow you to log into your instance.

For information about creating a security group, see Create an Amazon EC2 Security Group (p.18).

For information about authorizing security group ingress, see Authorize Amazon EC2 Security Group

Ingress (p. 19).

For information about creating a key pair, see Create a Key Pair (p. 19).

For information about running your Amazon EC2 instance, see Run an Amazon EC2 Instance (p. 20).

Create a Security Group

An Amazon EC2 security group controls traffic through your Amazon EC2 instances, much like a firewall.

If you do not create a security group, Amazon EC2 provides a default security group that allows no inbound

traffic. For more information about security groups, go to Security Group Concepts.

If you want to allow inbound traffic, create a security group and assign a rule to it that allows the ingress

that you want.Then associate the new security group with an Amazon EC2 instance. For more information,

see Authorize Security Group Ingress (p.19).

To create a security group, use the SecurityGroupCollection.create method and pass the name of a

security group you created.The method returns a SecurityGroup object, as follows:

security_group = ec2.security_groups.create('YOUR_SECURITY_GROUP_NAME')

The security group name must be unique within the AWS region in which you initialize your Amazon EC2

client.You must use US-ASCII characters for the security group name and description.

If you attempt to create a security group with the same name as an existing security group, the method

returns an error.

Before starting an Amazon EC2 instance, you next need to authorize security group ingress and create

a key pair to allow you to log into your instance.You can use the returned SecurityGroup object to

authorize or revoke security group ingress and egress.You must also create a key pair to allow you to

log into your instance.

For information about authorizing security group ingress, see Authorize Amazon EC2 Security Group

Ingress (p. 19).

For information about creating a key pair, see Create a Key Pair (p. 19).
