  • :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 Amazon Web Services-generated tags (tags that have the aws: prefix).

    A new description for the AMI.

  • :launch_permission (Types::LaunchPermissionModifications) —

    A new launch permission for the AMI.

    The operation type. This parameter can be used only when the Attribute parameter is launchPermission.

  • :product_codes (Array<String>) —

    Not supported.

  • :user_groups (Array<String>) —

    The user groups. This parameter can be used only when the Attribute parameter is launchPermission.

  • :user_ids (Array<String>) —

    The Amazon Web Services account IDs. This parameter can be used only when the Attribute parameter is launchPermission.

  • :value (String) —

    The value of the attribute being modified. This parameter can be used only when the Attribute parameter is description or imdsSupport.

  • :organization_arns (Array<String>) —

    The Amazon Resource Name (ARN) of an organization. This parameter can be used only when the Attribute parameter is launchPermission.

  • :organizational_unit_arns (Array<String>) —

In addition, HttpPutResponseHopLimit is set to 2. For more information, see Configure the AMI in the Amazon EC2 User Guide.

    Do not use this parameter unless your AMI software supports IMDSv2. After you set the value to v2.0, you can't undo it. The only way to “reset” your AMI is to create a new AMI from the underlying snapshot.

  • :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.

#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
