get-load-balancer¶

Description¶

Returns information about the specified Lightsail load balancer.

Synopsis¶

  get-load-balancer
--load-balancer-name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options¶

--load-balancer-name (string)

The name of the load balancer.

--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 information about a load balancer

The following get-load-balancer example displays details about the specified load balancer.

aws lightsail get-load-balancer \
    --load-balancer-name LoadBalancer-1

Output:

Output¶

loadBalancer -> (structure)

An object containing information about your load balancer.

name -> (string)

The name of the load balancer (e.g., my-load-balancer ).

arn -> (string)

The Amazon Resource Name (ARN) of the load balancer.

supportCode -> (string)

The support code. Include this code in your email to support when you have questions about your Lightsail load balancer. This code enables our support team to look up your Lightsail information more easily.

createdAt -> (timestamp)

The date when your load balancer was created.

location -> (structure)

The AWS Region where your load balancer was created (e.g., us-east-2a ). Lightsail automatically creates your load balancer across Availability Zones.

availabilityZone -> (string)

The Availability Zone. Follows the format us-east-2a (case-sensitive).

regionName -> (string)

The AWS Region name.

resourceType -> (string)

The resource type (e.g., LoadBalancer .

tags -> (list)

The tag keys and optional values for the resource. For more information about tags in Lightsail, see the Lightsail Dev Guide .

(structure)

Describes a tag key and optional value assigned to an Amazon Lightsail resource.

For more information about tags in Lightsail, see the Lightsail Dev Guide .

key -> (string)

The key of the tag.

Constraints: Tag keys accept a maximum of 128 letters, numbers, spaces in UTF-8, or the following characters: + - = . _ : / @

value -> (string)

The value of the tag.

Constraints: Tag values accept a maximum of 256 letters, numbers, spaces in UTF-8, or the following characters: + - = . _ : / @

dnsName -> (string)

The DNS name of your Lightsail load balancer.

state -> (string)

The status of your load balancer. Valid values are below.
