attach-load-balancers¶

Description¶

Note

To attach an Application Load Balancer, Network Load Balancer, or Gateway Load Balancer, use the AttachLoadBalancerTargetGroups API operation instead.

Attaches one or more Classic Load Balancers to the specified Auto Scaling group. Amazon EC2 Auto Scaling registers the running instances with these Classic Load Balancers.

To describe the load balancers for an Auto Scaling group, call the DescribeLoadBalancers API. To detach a load balancer from the Auto Scaling group, call the DetachLoadBalancers API.

This operation is additive and does not detach existing Classic Load Balancers or target groups from the Auto Scaling group.

For more information, see Use Elastic Load Balancing to distribute traffic across the instances in your Auto Scaling group in the Amazon EC2 Auto Scaling User Guide .

Synopsis¶

  attach-load-balancers
--auto-scaling-group-name <value>
--load-balancer-names <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--auto-scaling-group-name (string)

The name of the Auto Scaling group.

--load-balancer-names (list)

The names of the load balancers. You can specify up to 10 load balancers.

(string)

Syntax:

"string" "string" ...

--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.

See ‘aws help’ for descriptions of global 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 attach a Classic Load Balancer to an Auto Scaling group

This example attaches the specified Classic Load Balancer to the specified Auto Scaling group.

aws autoscaling attach-load-balancers \
    --load-balancer-names my-load-balancer \
    --auto-scaling-group-name my-asg

This command produces no output.
