update-ledger¶

Description¶

Updates properties on a ledger.

Synopsis¶

  update-ledger
--name <value>
[--deletion-protection | --no-deletion-protection]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--name (string)

The name of the ledger.

--deletion-protection | --no-deletion-protection (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.

--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.

See ‘aws help’ for descriptions of global parameters.
