用于检测LB（负载平衡器）而不附加实例的python脚本

Answer 1

假设您正在使用网络或应用程序负载平衡器，这可能会有所帮助，

import boto3 

my_client=boto3.client('elbv2', region_name='us-west-2', use_ssl='true')
response = my_client.describe_load_balancers()

for loadbalancer in (response["LoadBalancers"]):
    my_targetgroups=my_client.describe_target_groups(LoadBalancerArn=loadbalancer["LoadBalancerArn"])
    for my_targetgroup in my_targetgroups["TargetGroups"]:
        response_target=my_client.describe_target_health(TargetGroupArn=my_targetgroup["TargetGroupArn"])
        if response_target["TargetHealthDescriptions"]==[]:
            print (loadbalancer["LoadBalancerName"])
