    Parameters:

    • name (String)

    Options Hash (options):

  • #initialize(options = {}) ⇒ KeyPair

    Options Hash (options):

#client ⇒ Client

Returns:

# File 'lib/aws-sdk-ec2/key_pair.rb', line 70

def client: () -> Client

#data ⇒ Types::KeyPair

Returns the data for this Aws::EC2::KeyPair.

Returns:

Raises:

# File 'sig/key_pair.rbs', line 37

def data: () -> Types::KeyPair

#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.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:

#key_fingerprint ⇒ String

  • 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.

Returns:

  • (String)

def key_fingerprint: () -> ::String

#key_material ⇒ String

An unencrypted PEM encoded RSA or ED25519 private key.

Returns:

  • (String)

#key_pair_id ⇒ String

The ID of the key pair.

Returns:

  • (String)

#load ⇒ Object Also known as: reload

#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
