AutoScaling / Client / detach_traffic_sources

detach_traffic_sources#

AutoScaling.Client.detach_traffic_sources(**kwargs)#

Detaches one or more traffic sources from the specified Auto Scaling group.

When you detach a traffic source, it enters the Removing state while deregistering the instances in the group. When all instances are deregistered, then you can no longer describe the traffic source using the DescribeTrafficSources API call. The instances continue to run.

Request Syntax

response = client.detach_traffic_sources(
    AutoScalingGroupName='string',
    TrafficSources=[
        {
            'Identifier': 'string',
            'Type': 'string'
        },
    ]
)
Parameters:

  • AutoScalingGroupName (string) –

    [REQUIRED]

    The name of the Auto Scaling group.

  • TrafficSources (list) –

    [REQUIRED]

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

    • (dict) –

      Identifying information for a traffic source.

      • Identifier (string) – [REQUIRED]

        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.

Return type:

dict

Returns:

Examples

This example detaches the specified target group from the specified Auto Scaling group.

response = client.detach_traffic_sources(
    AutoScalingGroupName='my-auto-scaling-group',
    TrafficSources=[
        {
            'Identifier': 'arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/73e2d6bc24d8a067',
        },
    ],
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
