#create_time ⇒ Time

If you used Amazon EC2 to create the key pair, this is the date and time when the key was created, in [ISO 8601 date-time format], in the UTC time zone.

If you imported an existing key pair to Amazon EC2, this is the date and time the key was imported, in [ISO 8601 date-time format], in the UTC time zone.

#data ⇒ Types::KeyPairInfo

end

#data_loaded? ⇒ Boolean

Returns ‘true` if this resource is loaded. Accessing attributes or #data on an unloaded resource will trigger a call to #load.

Returns:

  • (Boolean) —

    Returns ‘true` if this resource is loaded. Accessing attributes or #data on an unloaded resource will trigger a call to #load.

#delete(options = {}) ⇒ Types::DeleteKeyPairResult

Examples:

Request syntax with placeholder values


key_pair_info.delete({
  key_pair_id: "KeyPairId",
  dry_run: false,
})

Parameters:

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

    ({})

Options Hash (options):

  • :key_pair_id (String) —

    The ID of the key pair.

  • :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`.

Returns:

#identifiers ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

  { name: @name }
end

#key_fingerprint ⇒ String

If you used CreateKeyPair to create the key pair:

  • For RSA key pairs, the key fingerprint is the SHA-1 digest of the DER encoded private key.

  • For ED25519 key pairs, the key fingerprint is the base64-encoded SHA-256 digest, which is the default for OpenSSH, starting with [OpenSSH 6.8].

If you used ImportKeyPair to provide Amazon Web Services the public key:

  • For RSA key pairs, the key fingerprint is the MD5 public key fingerprint as specified in section 4 of RFC4716.

  • For ED25519 key pairs, the key fingerprint is the base64-encoded SHA-256 digest, which is the default for OpenSSH, starting with [OpenSSH 6.8].

#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
