delete-known-host-keys

Description

Deletes the known host key or certificate used by the Amazon Lightsail browser-based SSH or RDP clients to authenticate an instance. This operation enables the Lightsail browser-based SSH or RDP clients to connect to the instance after a host key mismatch.

Warning

Perform this operation only if you were expecting the host key or certificate mismatch or if you are familiar with the new host key or certificate on the instance. For more information, see Troubleshooting connection issues when using the Amazon Lightsail browser-based SSH or RDP client .

See ‘aws help’ for descriptions of global parameters.

Synopsis

  delete-known-host-keys
--instance-name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--instance-name (string)

The name of the instance for which you want to reset the host key or certificate.

--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.
