在Boto3中等待ElasticLoadBalancingv2就绪的正确方法

import boto3

elbv2_client = boto3.client('elbv2')

# 创建负载均衡器
response = elbv2_client.create_load_balancer(
    Name='my-load-balancer',
    Subnets=[
        'subnet-12345678',
    ],
    SecurityGroups=[
        'sg-12345678',
    ],
    Type='application',
    Scheme='internet-facing'
)

# 获取负载均衡器的ARN
load_balancer_arn = response['LoadBalancers'][0]['LoadBalancerArn']

# 等待负载均衡器就绪
waiter = elbv2_client.get_waiter('load_balancer_available')
waiter.wait(
    LoadBalancerArns=[
        load_balancer_arn,
    ]
)

print("负载均衡器已就绪")
