如何打印 EC2 标签名称和 IP 地址？

Question

我有一个代码可以打印运行个实例的 Public IP，

regions = ['us-east-1','us-west-1','us-west-2','eu-west-1','sa-east-1','ap-southeast-1','ap-southeast-2','ap-northeast-1']
for region in regions:
  client = boto3.client('ec2',aws_access_key_id=ACCESS_KEY,aws_secret_access_key=SECRET_KEY,region_name=region,)
  addresses_dict = client.describe_addresses()
  for eip_dict in addresses_dict['Addresses']:
      if 'PrivateIpAddress' in eip_dict:
          print eip_dict['PublicIp']

很好，现在我还想打印 tag name 并将其存储在另一个字典中，我知道这可以通过 :

regions = ['us-east-1','us-west-1','us-west-2','eu-west-1','sa-east-1','ap-southeast-1','ap-southeast-2','ap-northeast-1']
for region in regions:
  client = boto3.client('ec2',aws_access_key_id=ACCESS_KEY,aws_secret_access_key=SECRET_KEY,region_name=region,)
  dex_dict = client.describe_tags()
  for dexy_dict in dex_dict['Tags']:
     print dexy_dict['Value']

问题是我如何将它组合到一个函数中并使用 2 个字典：一个存储 IP，另一个存储标签名称？请帮忙

试试下面的代码，它会给你一个字典，其中键是 InstanceId，值是 [PublicIP, Name].

的列表

import boto3

def instance_info():
    instance_information = {}
    ip_dict = {}
    client = boto3.client('ec2')
    addresses_dict = client.describe_addresses().get('Addresses')

    for address in addresses_dict:
        if address.get('InstanceId'):
            instance_information[address['InstanceId']] = [address.get('PublicIp')]

    dex_dict = client.describe_tags().get('Tags')
    for dex in dex_dict:
        if instance_information.get(dex['ResourceId']):
            instance_information[dex['ResourceId']].append(dex.get('Value'))

    for instance in instance_information:

        if len(instance_information[instance]) == 2:
            ip_dict[instance_information[instance][0]] = instance_information[instance][1]
        else:
            ip_dict[instance_information[instance][0]] = ''
    return instance_information, ip_dict
