--name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]


--name (string)

The name of the ledger that you want to describe.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.


To describe a ledger

aws qldb describe-ledger \
    --name myExampleLedger


    "CreationDateTime": 1568839243.951,
    "Arn": "arn:aws:qldb:us-west-2:123456789012:ledger/myExampleLedger",
    "State": "ACTIVE",

For more information, see Basic Operations for Amazon QLDB Ledgers in the Amazon QLDB Developer Guide.


Name -> (string)

The name of the ledger.

Arn -> (string)

The Amazon Resource Name (ARN) for the ledger.

State -> (string)

The current status of the ledger.

CreationDateTime -> (timestamp)

The date and time, in epoch time format, when the ledger was created. (Epoch time format is the number of seconds elapsed since 12:00:00 AM January 1, 1970 UTC.)

DeletionProtection -> (boolean)

The flag that prevents a ledger from being deleted by any user. If not provided on ledger creation, this feature is enabled (true ) by default.

If deletion protection is enabled, you must first disable it before you can delete the ledger using the QLDB API or the AWS Command Line Interface (AWS CLI). You can disable it by calling the UpdateLedger operation to set the flag to false . The QLDB console disables deletion protection for you when you use it to delete a ledger.
