使用Boto3（资源方法）创建图像 - 无法为快照添加标签？

Question

我有这个脚本：

#!/usr/bin/env python3

import boto3
import argparse
import time

ec2 = boto3.resource('ec2')

dstamp = time.strftime("_%m-%d-%Y-0")

parser = argparse.ArgumentParser(description='Create Image(AMI) from Instance tag:Name Value')
parser.add_argument('names', nargs='+', type=str.upper, help='instance name or list of names to create images from')
args = parser.parse_args()

# List Source Instances for Image/Tag Creation
for instance in ec2.instances.all():
  # Pull Name tags from source instances
  for name in instance.tags:
    if name["Key"] == 'Name':
      instancename = name["Value"]
      # Check for Name Tag Match with args
      for iname in args.names:
        if iname == instancename:
           # Create an image if we have a match
           image = instance.create_image(
           Description=f"Created from Source: {instance.id} Name: {instancename}",
           Name=instancename + dstamp,
           NoReboot=True)
           print('New: {} from instance.id: {} {}'.format(image.id, instance.id, instancename))
           # ----------------------------------------------
           # Can't copy tags from src instance - cause of auto-generated by Cloudformation Tags
           # error I got: "Tag keys starting with 'aws:' are reserved for internal use"
           # So we skip any tag [Key] named 'aws:'
           # ----------------------------------------------
           for tag in instance.tags:
             dst_tags = []
             if tag['Key'].startswith('aws:'):
               print("Skip tag that starts with 'aws:' " + tag['Key'])
             else:
               dst_tags.append(tag)
               print('     Tags:', dst_tags)
               image.create_tags(Tags=dst_tags)

这是完美的工作，但我缺少的最后一个功能是将标签应用于新创建的图像中的基础卷快照。我是否必须完全切换到client = boto3.client('ec2')才能标记我的卷快照？

换句话说 - 如何使用图像进行备份标记其卷快照？

我和boto3以及python 3一起工作了3个星期以及我的常规职责，我们将不胜感激。
