如何使用boto从运行中的实例创建EC2镜像？
我正在尝试为我的EC2实例创建一个简单的Python备份脚本。这个脚本的目的是每天或每周对当前的机器进行快照（可以参考这个ServerFault上的问题）。我使用的是boto这个Python包来操作EC2的API，并且想要从一个指定的实例创建一个EBS AMI（就像ElasticFox中的“创建镜像”操作一样）
# This script will look up all your running EC2 images, find the current one, and back it up by creating an AMI
# Configuration
accessKeyId = "..."
accessKeySecret = "..."
target = "..."
def resolveIp(target):
import socket
ip = repr(socket.gethostbyname_ex(target)[2][0])
return ip
def find_target(target, connection) :
ip = resolveIp(target)
print "Finding instance for " + target + " (IP " + ip + ")"
reservations = connection.get_all_instances();
for reservation in reservations:
instances = reservation.instances
if len(instances) != 1:
print "Skipping reservation " + reservation
continue
instance = instances[0]
instanceIp = resolveIp(instance.dns_name)
if instanceIp == ip:
return instance
raise Exception("Can't find instance with IP " + ip)
from boto.ec2.connection import EC2Connection
print "Connecting to EC2"
conn = EC2Connection(accessKeyId, accessKeySecret)
print "Connected to EC2"
instance = find_target(target, conn)
print "Backing up instance '{}'".format(instance)
# Now, I'd like to create a new image out of this instance
# Can you help?
（这也被报告为boto项目页面上的一个问题，因为我没有找到邮件列表）
