How to check an ELB is associated with any autoscaling group using Boto3

Question

How can I check whether an AWS Elastic Load Balancer, Application Load Balancer or Network Load Balancer is associated with any Auto-Scaling group by passing the Load Balancer name or Load Balancer ARN using Boto3?

Answer 1

The describe_auto_scaling_groups() command returns a list of LoadBalancerNames.

Therefore, you will need to:

• Call describe_auto_scaling_groups() to obtain a list of Auto Scaling groups
• Loop through each returned group and look at the LoadBalancerNames list
• Compare the entries with your Load Balancer name of interest
