Note

This is a Tagged Union structure. Only one of the following top level keys can be set: file, sds.

file -> (structure)

An object that represents a local file certificate. The certificate must meet specific requirements and you must have proxy authorization enabled. For more information, see Transport Layer Security (TLS) .

privateKey -> (string)

The private key for a certificate stored on the file system of the virtual node that the proxy is running on.

sds -> (structure)

A reference to an object that represents a client's TLS Secret Discovery Service certificate.

secretName -> (string)

A reference to an object that represents the name of the secret requested from the Secret Discovery Service provider representing Transport Layer Security (TLS) materials like a certificate or certificate chain.

--virtual-node-name (string)

The name of the virtual node to update.

--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. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--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.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.
