Overview

RightAWS::EC2 – RightScale Amazon EC2 interface

The RightAws::EC2 class provides a complete interface to Amazon’s Elastic Compute Cloud service, as well as the associated EBS (Elastic Block Store). For explanations of the semantics of each call, please refer to Amazon’s documentation at developer.amazonwebservices.com/connect/kbcategory.jspa?categoryID=87

Examples:

Create an EC2 interface handle:

@ec2   = RightAws::Ec2.new(aws_access_key_id,
                            aws_secret_access_key)

Create a new SSH key pair:

@key   = 'right_ec2_awesome_test_key'
new_key = @ec2.create_key_pair(@key)
keys = @ec2.describe_key_pairs

Create a security group:

@group = 'right_ec2_awesome_test_security_group'
@ec2.create_security_group(@group,'My awesome test group')
group = @ec2.describe_security_groups([@group])[0]

Configure a security group:

@ec2.authorize_security_group_named_ingress(@group, , 'default')
@ec2.authorize_security_group_IP_ingress(@group, 80,80,'udp','192.168.1.0/8')

Describe the available images:

images = @ec2.describe_images

Launch an instance:

ec2.run_instances('ami-9a9e7bf3', 1, 1, ['default'], @key, 'SomeImportantUserData', 'public')

Describe running instances:

@ec2.describe_instances

Error handling: all operations raise an RightAws::AwsError in case of problems. Note that transient errors are automatically retried.

Constructor Details

#initialize(aws_access_key_id = nil, aws_secret_access_key = nil, params = {}) ⇒ Ec2

Create a new handle to an EC2 account. All handles share the same per process or per thread HTTP connection to Amazon EC2. Each handle is for a specific account. The params have the following options:

  • :endpoint_url a fully qualified url to Amazon API endpoint (this overwrites: :server, :port, :service, :protocol and :region). Example: ‘eu-west-1.ec2.amazonaws.com/’

  • :server: EC2 service host, default: DEFAULT_HOST

  • :region: EC2 region (North America by default)

  • :port: EC2 service port, default: DEFAULT_PORT

  • :protocol: ‘http’ or ‘https’, default: DEFAULT_PROTOCOL

  • :multi_thread: true=HTTP connection per thread, false=per process

  • :logger: for log messages, default: RAILS_DEFAULT_LOGGER else STDOUT

  • :signature_version: The signature version : ‘0’,‘1’ or ‘2’(default)

  • :cache: true/false: caching for: ec2_describe_images, describe_instances,

describe_images_by_owner, describe_images_by_executable_by, describe_availability_zones, describe_security_groups, describe_key_pairs, describe_addresses, describe_volumes, describe_snapshots methods, default: false.

Bundle a Windows image. Internally, it queues the bundling task and shuts down the instance. It then takes a snapshot of the Windows volume bundles it, and uploads it to S3. After bundling completes, Rightaws::Ec2#register_image may be used to register the new Windows AMI for subsequent launches.

#try_create_snapshot(volume_id, connect_timeout = nil, read_timeout = nil) ⇒ Object

Create a snapshot of specified volume, but with the normal retry algorithms disabled. This method will return immediately upon error. The user can specify connect and read timeouts (in s) for the connection to AWS. If the user does not specify timeouts, try_create_snapshot uses the default values in Rightscale::HttpConnection.

     :aws_status     => "pending",
     :aws_id         => "snap-d56783bc"}
