Python BOTO3 脚本未返回标签内的名称

Python BOTO3 script is not returning name inside the tag

我需要提取 AWS EC2 的名称、实例 ID、状态并将其导出到 csv。通过使用下面的代码,我得到了实例 ID 和状态。名称在标签内,我的标签中有多个键值,如下所示:

“标签”:[ { “值”:“ggggg”, “键”:“bbbb” }, { “值”:“rrrrrr”, “关键”:“eeeeee” }, { "值": "uyyyutu", “关键”:“hhhhhh” }, { "值": "xxxxxxx", “键”:“名称” }, { “价值”:“绿色”, “键”:“状态” }, { "值": "xxxxx", “键”:“yyyyy” } ]

如何从特定的 KEY=NAME 获取名称。在使用以下代码时,我得到了标签中的所有值,它没有给出特定的值。

import boto3
import csv

client = boto3.client('ec2')

response = client.describe_instances(
    Filters=[
        {
        'Name':'tag:STATE','Values':['GREEN']
        }
    ]
)

detail=[]

for Reservations in response["Reservations"]:
    for Instances in Reservations["Instances"]:
        detail.append({
            'ID':Instances['InstanceId'],
            'Status':Instances['State']['Name'],
            'Name':Instances['Tags']['Key'=='Name']['Value']
        })

header=['ID','Status','Name']
with open('EC2_Detail.csv','w') as file:
    writer=csv.DictWriter(file, fieldnames=header)
    writer.writeheader()
    writer.writerows(detail)


尝试:

[x for x in Instances['Tags'] if x['Key'] == 'NAME'][0]['Value']

如果没有为特定实例定义标签名称,这将会中断。

tag_names = [x for x in Instances['Tags'] if x['Key'] == 'NAME']
if len(tag_names) > 0: name = tag_names[0]
