})

Parameters:

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

    ({})

Options Hash (options):

  • :tag_specifications (Array<Types::TagSpecification>) —

    The tags to apply to the AMI and snapshots on creation. You can tag the AMI, the snapshots, or both.

    • To tag the AMI, the value for ResourceType must be image.

    • To tag the snapshots that are created of the root volume and of other Amazon EBS volumes that are attached to the instance, the value for ResourceType must be snapshot. The same tag is applied to all of the snapshots that are created.

    If you specify other values for ResourceType, the request fails.

    To tag an AMI or snapshot after it has been created, see CreateTags.

  • :snapshot_location (String) —

    Only supported for instances in Local Zones. If the source instance is not in a Local Zone, omit this parameter.

    The Amazon S3 location where the snapshots will be stored.

    • To create local snapshots in the same Local Zone as the source instance, specify local.

    • To create regional snapshots in the parent Region of the Local Zone, specify regional or omit this parameter.

    Default: regional

  • :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.

  • :name (required, String) —

    A name for the new image.

    Constraints: 3-128 alphanumeric characters, parentheses (()), square brackets ([]), spaces ( ), periods (.), slashes (/), dashes (-), single quotes ('), at-signs (@), or underscores(_)

  • :description (String) —

    A description for the new image.

  • :no_reboot (Boolean) —

    Indicates whether or not the instance should be automatically rebooted before creating the image. Specify one of the following values:

    • true - The instance is not rebooted before creating the image. This creates crash-consistent snapshots that include only the data that has been written to the volumes at the time the snapshots are created. Buffered data and data in memory that has not yet been written to the volumes is not included in the snapshots.

    • false - The instance is rebooted before creating the image. This ensures that all buffered data and data in memory is written to the volumes before the snapshots are created.

    Default: false

  • :block_device_mappings (Array<Types::BlockDeviceMapping>) —

    The block device mappings.

    When using the CreateImage action:

    • You can't change the volume size using the VolumeSize parameter. If you want a different volume size, you must first change the volume size of the source instance.

    • You can't modify the encryption status of existing volumes or snapshots. To create an AMI with volumes or snapshots that have a different encryption status (for example, where the source volume and snapshots are unencrypted, and you want to create an AMI with encrypted volumes or snapshots), copy the image instead.

    • The only option that can be changed for existing mappings or snapshots is DeleteOnTermination.

})

Parameters:

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

    ({})

Options Hash (options):

  • :source_dest_check (Types::AttributeBooleanValue) —

    Enable or disable source/destination checks, which ensure that the instance is either the source or the destination of any traffic that it receives. If the value is true, source/destination checks are enabled; otherwise, they are disabled. The default value is true. You must disable source/destination checks if the instance runs services such as network address translation, routing, or firewalls.

  • :disable_api_stop (Types::AttributeBooleanValue) —

    Indicates whether an instance is enabled for stop protection. For more information, see Enable stop protection for your instance.

  • :dry_run (Boolean) —

    Checks whether you have the required permissions for the operation, 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.

  • :attribute (String) —

    The name of the attribute to modify.

    When changing the instance type: If the original instance type is configured for configurable bandwidth, and the desired instance type doesn't support configurable bandwidth, first set the existing bandwidth configuration to default using the ModifyInstanceNetworkPerformanceOptions operation.

    You can modify the following attributes only: disableApiTermination | instanceType | kernel | ramdisk | instanceInitiatedShutdownBehavior | blockDeviceMapping | userData | sourceDestCheck | groupSet | ebsOptimized | sriovNetSupport | enaSupport | nvmeSupport | disableApiStop | enclaveOptions

  • :value (String) —

    A new value for the attribute. Use only with the kernel, ramdisk, userData, disableApiTermination, or instanceInitiatedShutdownBehavior attribute.

  • :block_device_mappings (Array<Types::InstanceBlockDeviceMappingSpecification>) —

    Modifies the DeleteOnTermination attribute for volumes that are currently attached. The volume must be owned by the caller. If no value is specified for DeleteOnTermination, the default is true and the volume is deleted when the instance is terminated. You can't modify the DeleteOnTermination attribute for volumes that are attached to Amazon Web Services-managed resources.

    To add instance store volumes to an Amazon EBS-backed instance, you must add them when you launch the instance. For more information, see Update the block device mapping when launching an instance in the Amazon EC2 User Guide.

  • :disable_api_termination (Types::AttributeBooleanValue) —

    Enable or disable termination protection for the instance. If the value is true, you can't terminate the instance using the Amazon EC2 console, command line interface, or API. You can't enable termination protection for Spot Instances.

  • :instance_type (Types::AttributeValue) —

    Changes the instance type to the specified value. For more information, see Instance types in the Amazon EC2 User Guide. If the instance type is not valid, the error returned is InvalidInstanceAttributeValue.

  • :kernel (Types::AttributeValue) —

    Changes the instance's kernel to the specified value. We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see PV-GRUB.

  • :ramdisk (Types::AttributeValue) —

    Changes the instance's RAM disk to the specified value. We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see PV-GRUB.

  • :user_data (Types::BlobAttributeValue) —

    Changes the instance's user data to the specified value. User data must be base64-encoded. Depending on the tool or SDK that you're using, the base64-encoding might be performed for you. For more information, see Work with instance user data.

  • :instance_initiated_shutdown_behavior (Types::AttributeValue) —

    Specifies whether an instance stops or terminates when you initiate shutdown from the instance (using the operating system command for system shutdown).

  • :groups (Array<String>) —

    Replaces the security groups of the instance with the specified security groups. You must specify the ID of at least one security group, even if it's just the default security group for the VPC.

  • :ebs_optimized (Types::AttributeBooleanValue) —

    Specifies 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 EBS I/O performance. This optimization isn't available with all instance types. Additional usage charges apply when using an EBS Optimized instance.

  • :sriov_net_support (Types::AttributeValue) —

    Set to simple to enable enhanced networking with the Intel 82599 Virtual Function interface for the instance.

    There is no way to disable enhanced networking with the Intel 82599 Virtual Function interface at this time.

    This option is supported only for HVM instances. Specifying this option with a PV instance can make it unreachable.

  • :ena_support (Types::AttributeBooleanValue) —

    Set to true to enable enhanced networking with ENA for the instance.

    This option is supported only for HVM instances. Specifying this option with a PV instance can make it unreachable.

Returns:

#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
