[--cli-binary-format <value>]
[--no-cli-pager]
[--cli-auto-prompt]
[--no-cli-auto-prompt]

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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

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.

--output (string)

The formatting style for command output.

json
text
table
yaml
yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

on
off
auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

base64
raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To describe the attributes of a load balancer

This example describes the attributes of the specified load balancer.

Command:

aws elb describe-load-balancer-attributes --load-balancer-name my-load-balancer

Output:

{
  "LoadBalancerAttributes": {
      "ConnectionDraining": {
          "Enabled": false,
          "Timeout": 300
      },
      "CrossZoneLoadBalancing": {
          "Enabled": true
      },
      "ConnectionSettings": {
          "IdleTimeout": 30
      },
      "AccessLog": {
          "Enabled": false
    }
  }
}

Output¶

LoadBalancerAttributes -> (structure)

Information about the load balancer attributes.

CrossZoneLoadBalancing -> (structure)

If enabled, the load balancer routes the request traffic evenly across all instances regardless of the Availability Zones.

For more information, see Configure Cross-Zone Load Balancing in the Classic Load Balancers Guide .

Enabled -> (boolean)

Specifies whether cross-zone load balancing is enabled for the load balancer.

AccessLog -> (structure)

If enabled, the load balancer captures detailed information of all requests and delivers the information to the Amazon S3 bucket that you specify.

For more information, see Enable Access Logs in the Classic Load Balancers Guide .

Enabled -> (boolean)

Specifies whether access logs are enabled for the load balancer.

S3BucketName -> (string)

The name of the Amazon S3 bucket where the access logs are stored.

EmitInterval -> (integer)

The interval for publishing the access logs. You can specify an interval of either 5 minutes or 60 minutes.

Default: 60 minutes

S3BucketPrefix -> (string)

The logical hierarchy you created for your Amazon S3 bucket, for example my-bucket-prefix/prod . If the prefix is not provided, the log is placed at the root level of the bucket.

ConnectionDraining -> (structure)

If enabled, the load balancer allows existing requests to complete before the load balancer shifts traffic away from a deregistered or unhealthy instance.

For more information, see Configure Connection Draining in the Classic Load Balancers Guide .

Enabled -> (boolean)

Specifies whether connection draining is enabled for the load balancer.

Timeout -> (integer)

The maximum time, in seconds, to keep the existing connections open before deregistering the instances.

ConnectionSettings -> (structure)

If enabled, the load balancer allows the connections to remain idle (no data is sent over the connection) for the specified duration.

By default, Elastic Load Balancing maintains a 60-second idle connection timeout for both front-end and back-end connections of your load balancer. For more information, see Configure Idle Connection Timeout in the Classic Load Balancers Guide .

IdleTimeout -> (integer)

The time, in seconds, that the connection is allowed to be idle (no data has been sent over the connection) before it is closed by the load balancer.

AdditionalAttributes -> (list)

Any additional attributes.

(structure)

Information about additional load balancer attributes.

Key -> (string)

The name of the attribute.

The following attribute is supported.

elb.http.desyncmitigationmode - Determines how the load balancer handles requests that might pose a security risk to your application. The possible values are monitor , defensive , and strictest . The default is defensive .

Value -> (string)

This value of the attribute.
