containerPort -> (integer)

hostPort -> (integer)

The port number on the host that's used with the network binding.

protocol -> (string)

The protocol used for the network binding.

Shorthand Syntax:

bindIP=string,containerPort=integer,hostPort=integer,protocol=string ...

JSON Syntax:

    "bindIP": "string",
    "containerPort": integer,
    "hostPort": integer,
    "protocol": "tcp"|"udp"

--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.

See 'aws help' for descriptions of global parameters.


acknowledgment -> (string)

Acknowledgement of the state change.
