[ aws . autoscaling ]

attach-traffic-sources

Description

Attaches one or more traffic sources to the specified Auto Scaling group.

You can use any of the following as traffic sources for an Auto Scaling group:

  • Application Load Balancer
  • Classic Load Balancer
  • Gateway Load Balancer
  • Network Load Balancer
  • VPC Lattice

This operation is additive and does not detach existing traffic sources from the Auto Scaling group.

After the operation completes, use the DescribeTrafficSources API to return details about the state of the attachments between traffic sources and your Auto Scaling group. To detach a traffic source from the Auto Scaling group, call the DetachTrafficSources API.

Options

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

The name of the Auto Scaling group.

--traffic-sources (list)

The unique identifiers of one or more traffic sources. You can specify up to 10 traffic sources.

(structure)

Identifying information for a traffic source.

Identifier -> (string)

Identifies the traffic source.

For Application Load Balancers, Gateway Load Balancers, Network Load Balancers, and VPC Lattice, this will be the Amazon Resource Name (ARN) for a target group in this account and Region. For Classic Load Balancers, this will be the name of the Classic Load Balancer in this account and Region.

For example:

  • Application Load Balancer ARN: arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/1234567890123456
  • Classic Load Balancer name: my-classic-load-balancer
  • VPC Lattice ARN: arn:aws:vpc-lattice:us-west-2:123456789012:targetgroup/tg-1234567890123456

To get the ARN of a target group for a Application Load Balancer, Gateway Load Balancer, or Network Load Balancer, or the name of a Classic Load Balancer, use the Elastic Load Balancing DescribeTargetGroups and DescribeLoadBalancers API operations.

To get the ARN of a target group for VPC Lattice, use the VPC Lattice GetTargetGroup API operation.

Type -> (string)

Provides additional context for the value of Identifier .

The following lists the valid values:

  • elb if Identifier is the name of a Classic Load Balancer.
  • elbv2 if Identifier is the ARN of an Application Load Balancer, Gateway Load Balancer, or Network Load Balancer target group.
  • vpc-lattice if Identifier is the ARN of a VPC Lattice target group.

Required if the identifier is the name of a Classic Load Balancer.

Shorthand Syntax:

Identifier=string,Type=string ...

JSON Syntax:

[
  {
    "Identifier": "string",
    "Type": "string"
  }
  ...
]

--skip-zonal-shift-validation | --no-skip-zonal-shift-validation (boolean)

If you enable zonal shift with cross-zone disabled load balancers, capacity could become imbalanced across Availability Zones. To skip the validation, specify true . For more information, see Auto Scaling group zonal shift in the Amazon EC2 Auto Scaling User Guide .

--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.

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. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--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.

Output

None
