  • :tags (Array<Types::Tag>)

    The tags to delete. Specify a tag key and an optional tag value to delete specific tags. If you specify a tag key without a tag value, we delete any tag with this key regardless of its value. If you specify a tag key with an empty string as the tag value, we delete the tag only if its value is an empty string.

    If you omit this parameter, we delete all user-defined tags for the specified resources. We do not delete AWS-generated tags (tags that have the aws: prefix).

    ({})

Options Hash (options):

  • :device (String)

    The device name.

  • :force (Boolean)

    Forces detachment if the previous detachment attempt did not occur cleanly (for example, logging into an instance, unmounting the volume, and detaching normally). This option can lead to data loss or a corrupted file system. Use this option only as a last resort to detach a volume from a failed instance. The instance won't have an opportunity to flush file system caches or file system metadata. If you use this option, you must perform file system check and repair procedures.

  • :volume_id (required, String)

    The ID of the volume.

Parameters:

  • options (Hash) (defaults to: {})

    ({})

Options Hash (options):

  • :source_dest_check (Types::AttributeBooleanValue)

    Specifies whether source/destination checking is enabled. A value of true means that checking is enabled, and false means that checking is disabled. This value must be false for a NAT instance to perform NAT.

  • :attribute (String)

    The name of the 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.

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

  • :disable_api_termination (Types::AttributeBooleanValue)

    If the value is true, you can't terminate the instance using the Amazon EC2 console, CLI, or API; otherwise, you can. You cannot use this parameter for Spot Instances.

  • :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 (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.

  • :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.

  • :groups (Array<String>)

    [EC2-VPC] Changes the security groups of the instance. You must specify at least one security group, even if it's just the default security group for the VPC. You must specify the security group ID, not the security group name.

  • :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).

  • :instance_type (Types::AttributeValue)

    Changes the instance type to the specified value. For more information, see Instance types. 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.

  • :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.

  • :user_data (Types::BlobAttributeValue)

    Changes the instance's user data to the specified value. If you are using an AWS SDK or 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.

  • :value (String)

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

Returns:

  • (EmptyStructure)

#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
