Question

我需要从AWS精确地列出所有正在运行的IP，并且在IP列表中我还需要标记值＆amp; region-name（或availability-zone）。该列表应如下所示

ex : [[('23.1.1.141', ' Production LB', 'us-east-1'), ('47.2.14.93', 'sung2-cloud-trial01-LBi-b89671', 'us-west-2'),................]]

该清单包括以下内容：

<'Running IP'>,<'Tag-value'>,<AvailabilityZone>

使用boto3，我可以使用describe_instances()实现此目的，因此我尝试按如下方式使用它：

def gather_public_ip():
    regions = ['us-west-2', 'eu-central-1', 'ap-southeast-1']
    combined_list = []   ##This needs to be returned 
    for region in regions:
        instance_information = {}
        ip_dict = {}
        client = boto3.client('ec2', aws_access_key_id=ACCESS_KEY, aws_secret_access_key=SECRET_KEY,
                              region_name=region, )
        instance_dict = client.describe_instances().get('Reservations')
        for instance in instance_dict:
            .....
            #WHAT CODE COMES HERE???

gather_public_ip()

那么究竟应该为此寻找什么呢？我不知道该怎么做，请帮忙

我认为这完全取决于在回复中找到信息并抓住它;

def gather_public_ip():
    regions = ['us-west-2', 'eu-central-1', 'ap-southeast-1']
    combined_list = []   ##This needs to be returned 
    for region in regions:
        instance_information = [] # I assume this is a list, not dict
        ip_dict = {}
        client = boto3.client('ec2', aws_access_key_id=ACCESS_KEY, aws_secret_access_key=SECRET_KEY,
                              region_name=region, )
        instance_dict = client.describe_instances().get('Reservations')
        for reservation in instance_dict:
            for instance in reservation['Instances']: # This is rather not obvious
                if instance[unicode('State')][unicode('Name')] == 'running':
                    try:
                        ipaddress = instance[unicode('PublicIpAddress')]
                    except:
                        break
                    tagValue = instance[unicode('Tags')][0][unicode('Value')] # 'Tags' is a list, took the first element, you might wanna switch this
                    zone = instances[unicode('Placement')][unicode('AvailabilityZone')]
                    info = ipaddress, tagValue, zone
                    instance_information.append(info)
        combined_list.append(instance_information)
    return combined_list

gather_public_ip()

我希望这是您正在寻找的内容，我也希望您不要直接复制，但请查看我如何从文档中的返回dict中提取信息。

Answer 2

尝试ip_addr = instance_dict['Reservations'][0]['Instances'][0]['PublicIpAddress']来获取IP地址。 describe_instaces()响应是一个字典，其值是包含多个其他字典的数组，依此类推。...
