从 AWS 中提取 运行 个 IP 的列表
Extract the list of running IP's from AWS
我需要从 AWS 中提取所有 运行 IP 的列表，沿着 IP 列表我还需要标签值和区域名称（或可用性区域）。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'),................]]
列表包括以下内容：
<'Running IP'>,<'Tag-value'>,<AvailabilityZone>
使用 boto3 我可以使用 describe_instances() 实现这一点，所以我尝试如下使用它：
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()
那么我到底应该调查什么？我不知道该怎么做，请帮忙

我觉得就是在响应中找到信息并抓取它；
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()
我希望这就是你要找的，我也希望你不要直接复制它，而是看看我是如何从文档中的 return dict 中提取信息的.
尝试 ip_addr = instance_dict['Reservations'][0]['Instances'][0]['PublicIpAddress'] 获取 IP 地址。 describe_instaces() response 是一个字典，其值是一个包含多个其他字典等的数组....
