get-instance-port-states

Description

Returns the firewall port states for a specific Amazon Lightsail instance, the IP addresses allowed to connect to the instance through the ports, and the protocol.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

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

Options

--instance-name (string)

The name of the instance for which to return firewall port states.

--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.

Examples

To get firewall information for an instance

The following get-instance-port-states example returns the firewall ports configured for instance MEAN-1.

aws lightsail get-instance-port-states \
    --instance-name MEAN-1

Output:

{
    "portStates": [
        {
            "fromPort": 80,
            "toPort": 80,
            "protocol": "tcp",
            "state": "open"
        },
        {
            "fromPort": 22,
            "toPort": 22,
            "protocol": "tcp",
            "state": "open"
        },
        {
            "fromPort": 443,
            "toPort": 443,
            "protocol": "tcp",
            "state": "open"
        }
    ]
}

Output

portStates -> (list)

An array of objects that describe the firewall port states for the specified instance.

(structure)

Describes open ports on an instance, the IP addresses allowed to connect to the instance through the ports, and the protocol.

fromPort -> (integer)

The first port in a range of open ports on an instance.

Allowed ports:

• TCP and UDP - 0 to 65535

• ICMP - The ICMP type. For example, specify 8 as the fromPort (ICMP type), and -1 as the toPort (ICMP code), to enable ICMP Ping. For more information, see Control Messages on Wikipedia .

toPort -> (integer)

The last port in a range of open ports on an instance.

Allowed ports:

• TCP and UDP - 0 to 65535

• ICMP - The ICMP code. For example, specify 8 as the fromPort (ICMP type), and -1 as the toPort (ICMP code), to enable ICMP Ping. For more information, see Control Messages on Wikipedia .

protocol -> (string)

The IP protocol name.

The name can be one of the following:

• tcp - Transmission Control Protocol (TCP) provides reliable, ordered, and error-checked delivery of streamed data between applications running on hosts communicating by an IP network. If you have an application that doesn’t require reliable data stream service, use UDP instead.

• all - All transport layer protocol types. For more general information, see Transport layer on Wikipedia .

• udp - With User Datagram Protocol (UDP), computer applications can send messages (or datagrams) to other hosts on an Internet Protocol (IP) network. Prior communications are not required to set up transmission channels or data paths. Applications that don’t require reliable data stream service can use UDP, which provides a connectionless datagram service that emphasizes reduced latency over reliability. If you do require reliable data stream service, use TCP instead.

• icmp - Internet Control Message Protocol (ICMP) is used to send error messages and operational information indicating success or failure when communicating with an instance. For example, an error is indicated when an instance could not be reached. When you specify icmp as the protocol , you must specify the ICMP type using the fromPort parameter, and ICMP code using the toPort parameter.

state -> (string)

Specifies whether the instance port is open or closed .

Note

The port state for Lightsail instances is always open .

cidrs -> (list)

The IP address, or range of IP addresses in CIDR notation, that are allowed to connect to an instance through the ports, and the protocol. Lightsail supports IPv4 addresses.

For more information about CIDR block notation, see Classless Inter-Domain Routing on Wikipedia .

(string)

cidrListAliases -> (list)

An alias that defines access for a preconfigured range of IP addresses.

The only alias currently supported is lightsail-connect , which allows IP addresses of the browser-based RDP/SSH client in the Lightsail console to connect to your instance.

(string)
