使用boto3在AWS帐户中取消标记ec2实例的列表

Question

The code below is giving me the result for one specified region, can anyone help me how to get all untagged ec2 instances information across all regions in one aws account?

#!/usr/bin/env python
import boto3
import json, ast

instances = [i for i in boto3.resource('ec2', region_name='us-east-2').instances.all()]

for i in instances:
    d = (i.tags[0])
    d2 = ast.literal_eval(json.dumps(d))
    if ( d2['Value'] == "" ):
            print i.instance_id

Answer 1

Get list of all regions. Loop through each region and execute your code. Something like this:

def do_tags(region):
  instances = [i for i in boto3.resource('ec2', region_name=region).instances.all()]

  for i in instances:
      d = (i.tags[0])
      d2 = ast.literal_eval(json.dumps(d))
      if ( d2['Value'] == "" ):
              print i.instance_id

regions = boto3.session.Session().get_available_regions('ec2')
for region in regions:
  print 'Checking region:', region
  do_tags(region)
