[ aws . ec2 ]



Retrieves the encrypted administrator password for an instance running Windows.

The Windows password is generated at boot if the EC2Config service plugin, Ec2SetPassword , is enabled. This usually only happens the first time an AMI is launched, and then Ec2SetPassword is automatically disabled. The password is not generated for rebundled AMIs unless Ec2SetPassword is enabled before bundling.

The password is encrypted using the key pair that you specified when you launched the instance. You must provide the corresponding key pair file.

Password generation and encryption takes a few moments. We recommend that you wait up to 15 minutes after launching an instance before trying to retrieve the generated password.

--instance-id <value>
[--dry-run | --no-dry-run]
[--priv-launch-key <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--instance-id (string)

The ID of the Windows instance.

--dry-run | --no-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 .

--priv-launch-key (string)

The file that contains the private key used to launch the instance (e.g. windows-keypair.pem). If this is supplied, the password data sent from EC2 will be decrypted before display.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
