Parameters:

options (Hash) (defaults to: {}) —
({})

Options Hash (options):

:block_device_mappings (Array<Types::BlockDeviceMapping>) —
The block device mapping entries.
:image_id (String) —
The ID of the AMI. An AMI ID is required to launch an instance and must be specified here or in a launch template.
:instance_type (String) —
The instance type. For more information, see Instance types in the Amazon EC2 User Guide.

Default: m1.small
:ipv_6_address_count (Integer) —
[EC2-VPC] The number of IPv6 addresses to associate with the primary network interface. Amazon EC2 chooses the IPv6 addresses from the range of your subnet. You cannot specify this option and the option to assign specific IPv6 addresses in the same request. You can specify this option if you've specified a minimum number of instances to launch.

You cannot specify this option and the network interfaces option in the same request.
:ipv_6_addresses (Array<Types::InstanceIpv6Address>) —
[EC2-VPC] The IPv6 addresses from the range of the subnet to associate with the primary network interface. You cannot specify this option and the option to assign a number of IPv6 addresses in the same request. You cannot specify this option if you've specified a minimum number of instances to launch.

You cannot specify this option and the network interfaces option in the same request.
:kernel_id (String) —
The ID of the kernel.

We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see PV-GRUB in the Amazon EC2 User Guide.
:key_name (String) —
The name of the key pair. You can create a key pair using CreateKeyPair or ImportKeyPair.

If you do not specify a key pair, you can't connect to the instance unless you choose an AMI that is configured to allow users another way to log in.
:max_count (required, Integer) —
The maximum number of instances to launch. If you specify more instances than Amazon EC2 can launch in the target Availability Zone, Amazon EC2 launches the largest possible number of instances above MinCount.

Constraints: Between 1 and the maximum number you're allowed for the specified instance type. For more information about the default limits, and how to request an increase, see How many instances can I run in Amazon EC2 in the Amazon EC2 FAQ.
:min_count (required, Integer) —
The minimum number of instances to launch. If you specify a minimum that is more instances than Amazon EC2 can launch in the target Availability Zone, Amazon EC2 launches no instances.

Constraints: Between 1 and the maximum number you're allowed for the specified instance type. For more information about the default limits, and how to request an increase, see How many instances can I run in Amazon EC2 in the Amazon EC2 General FAQ.
:monitoring (Types::RunInstancesMonitoringEnabled) —
Specifies whether detailed monitoring is enabled for the instance.
:placement (Types::Placement) —
The placement for the instance.
:ramdisk_id (String) —
The ID of the RAM disk to select. Some kernels require additional drivers at launch. Check the kernel requirements for information about whether you need to specify a RAM disk. To find kernel requirements, go to the AWS Resource Center and search for the kernel ID.

We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see PV-GRUB in the Amazon EC2 User Guide.
:security_group_ids (Array<String>) —
The IDs of the security groups. You can create a security group using CreateSecurityGroup.

If you specify a network interface, you must specify any security groups as part of the network interface.
:security_groups (Array<String>) —
[EC2-Classic, default VPC] The names of the security groups. For a nondefault VPC, you must use security group IDs instead.

If you specify a network interface, you must specify any security groups as part of the network interface.

Default: Amazon EC2 uses the default security group.
:user_data (String) —
The user data to make available to the instance. For more information, see Running commands on your Linux instance at launch (Linux) and Adding User Data (Windows). If you are using a command line tool, base64-encoding is performed for you, and you can load the text from a file. Otherwise, you must provide base64-encoded text. User data is limited to 16 KB.
:additional_info (String) —
Reserved.
:client_token (String) —
Unique, case-sensitive identifier you provide to ensure the idempotency of the request. If you do not specify a client token, a randomly generated token is used for the request to ensure idempotency.

For more information, see Ensuring Idempotency.

Constraints: Maximum 64 ASCII characters
:disable_api_termination (Boolean) —
If you set this parameter to true, you can't terminate the instance using the Amazon EC2 console, CLI, or API; otherwise, you can. To change this attribute after launch, use ModifyInstanceAttribute. Alternatively, if you set InstanceInitiatedShutdownBehavior to terminate, you can terminate the instance by running the shutdown command from the instance.

Default: false
:dry_run (Boolean) —
Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.
:ebs_optimized (Boolean) —
Indicates whether the instance is optimized for Amazon EBS I/O. This optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal Amazon EBS I/O performance. This optimization isn't available with all instance types. Additional usage charges apply when using an EBS-optimized instance.

Default: false
:iam_instance_profile (Types::IamInstanceProfileSpecification) —
The name or Amazon Resource Name (ARN) of an IAM instance profile.
:instance_initiated_shutdown_behavior (String) —
Indicates whether an instance stops or terminates when you initiate shutdown from the instance (using the operating system command for system shutdown).

Default: stop
:network_interfaces (Array<Types::InstanceNetworkInterfaceSpecification>) —
The network interfaces to associate with the instance. If you specify a network interface, you must specify any security groups and subnets as part of the network interface.
:private_ip_address (String) —
[EC2-VPC] The primary IPv4 address. You must specify a value from the IPv4 address range of the subnet.

Only one private IP address can be designated as primary. You can't specify this option if you've specified the option to designate a private IP address as the primary IP address in a network interface specification. You cannot specify this option if you're launching more than one instance in the request.

You cannot specify this option and the network interfaces option in the same request.
:elastic_gpu_specification (Array<Types::ElasticGpuSpecification>) —
An elastic GPU to associate with the instance. An Elastic GPU is a GPU resource that you can attach to your Windows instance to accelerate the graphics performance of your applications. For more information, see Amazon EC2 Elastic GPUs in the Amazon EC2 User Guide.
:elastic_inference_accelerators (Array<Types::ElasticInferenceAccelerator>) —
An elastic inference accelerator to associate with the instance. Elastic inference accelerators are a resource you can attach to your Amazon EC2 instances to accelerate your Deep Learning (DL) inference workloads.

You cannot specify accelerators from different generations in the same request.
:tag_specifications (Array<Types::TagSpecification>) —

Options Hash (options):

:description (String) —
A description for the network interface.
:dry_run (Boolean) —
Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.
:groups (Array<String>) —
The IDs of one or more security groups.
:ipv_6_address_count (Integer) —
The number of IPv6 addresses to assign to a network interface. Amazon EC2 automatically selects the IPv6 addresses from the subnet range. You can't use this option if specifying specific IPv6 addresses. If your subnet has the AssignIpv6AddressOnCreation attribute set to true, you can specify 0 to override this setting.
:ipv_6_addresses (Array<Types::InstanceIpv6Address>) —
One or more specific IPv6 addresses from the IPv6 CIDR block range of your subnet. You can't use this option if you're specifying a number of IPv6 addresses.
:private_ip_address (String) —
The primary private IPv4 address of the network interface. If you don't specify an IPv4 address, Amazon EC2 selects one for you from the subnet's IPv4 CIDR range. If you specify an IP address, you cannot indicate any IP addresses specified in privateIpAddresses as primary (only one IP address can be designated as primary).
:private_ip_addresses (Array<Types::PrivateIpAddressSpecification>) —
One or more private IPv4 addresses.
:secondary_private_ip_address_count (Integer) —
The number of secondary private IPv4 addresses to assign to a network interface. When you specify a number of secondary IPv4 addresses, Amazon EC2 selects these IP addresses within the subnet's IPv4 CIDR range. You can't specify this option and specify more than one private IP address using privateIpAddresses.

The number of IP addresses you can assign to a network interface varies by instance type. For more information, see IP Addresses Per ENI Per Instance Type in the Amazon Virtual Private Cloud User Guide.

#wait_until(options = {}) {|resource| ... } ⇒ `Resource`

Deprecated.

Use [Aws::EC2::Client] #wait_until instead

Note:

The waiting operation is performed on a copy. The original resource remains unchanged.

Waiter polls an API operation until a resource enters a desired state.

Basic Usage

Waiter will polls until it is successful, it fails by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop until condition is true
resource.wait_until(options) {|resource| condition}

Example

instance.wait_until(max_attempts:10, delay:5) do |instance|
  instance.state.name == 'running'
end

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. The waiting condition is set by passing a block to #wait_until:

# poll for ~25 seconds
resource.wait_until(max_attempts:5,delay:5) {|resource|...}

Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
# poll for 1 hour, instead of a number of attempts
proc = Proc.new do |attempts, response|
  throw :failure if Time.now - started_at > 3600
end

  # disable max attempts
instance.wait_until(before_wait:proc, max_attempts:nil) {...}

Handling Errors

When a waiter is successful, it returns the Resource. When a waiter fails, it raises an error.

begin
  resource.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

attempts attempt in seconds invoked before each attempt invoked before each wait

Parameters:

options (Hash) (defaults to: {}) —
a customizable set of options

Options Hash (options):

:max_attempts (Integer) — default: 10 —
Maximum number of
:delay (Integer) — default: 10 —
Delay between each
:before_attempt (Proc) — default: nil —
Callback
:before_wait (Proc) — default: nil —
Callback

Yield Parameters:

resource (Resource) —
to be used in the waiting condition.

Returns:

(Resource) —
if the waiter was successful

Raises:

(Aws::Waiters::Errors::FailureStateError) —
Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

yet successful.
(Aws::Waiters::Errors::UnexpectedError) —
Raised when an error is encountered while polling for a resource that is not expected.
(NotImplementedError) —
Raised when the resource does not
