amazon-web-services - 如何从AWS删除多个堆栈？

Question

我正在 AWS 上工作，这里部署了多个 cloudformations 堆栈。现在我想立即删除它们，以便我可以重新铺设环境。

但是我没有找到任何方法可以做到这一点。我正在使用以下命令来查看堆栈列表。

aws cloudformation list-stacks 

有人可以帮忙吗，我现在如何删除所有堆栈？

您可以运行一个简短的 python 脚本来迭代堆栈。

    import boto3
    
    cf_client = boto3.client('cloudformation', region_name="us-east-1")
    
    for stack in cf_client.describe_stacks()['Stacks']:
        print("deleting {}".format(stack['StackName']))
        cf_client.delete_stack(StackName=stack['StackName'])

如果您想处理终止保护、删除失败和等待等边缘情况，请使用:

 import boto3
 
 cf_client = boto3.client('cloudformation', region_name="us-east-1")
 deletion_waiter = cf_client.get_waiter('stack_delete_complete')
 cloudformation = boto3.resource('cloudformation')
 
 
 stack_list = cf_client.describe_stacks()['Stacks']
 for st in stack_list:
     stack = cloudformation.Stack(st['StackName'])
     cf_client.update_termination_protection(EnableTerminationProtection=False,StackName=stack.stack_name)
     print(stack.stack_name)
     if stack.stack_status == 'DELETE_FAILED':
         retain_resource = stack.stack_status_reason.split('[')[-1].split(']')[0]
         print("deleting {} while retaining {} ".format(stack.stack_name, retain_resource))
         cf_client.delete_stack(StackName=stack.stack_name, RetainResources=[retain_resource])
     else:
         print("deleting {}".format(stack.stack_name))
         cf_client.delete_stack(StackName=stack.stack_name)
     deletion_waiter.wait( StackName=stack.stack_name,WaiterConfig={'Delay': 30,'MaxAttempts': 6})
