如何從以前的EC2實例的AMI啓動VPC中的EC2實例的完全相同的副本

我有一個EC2實例A，不能重新啓動，但問題是它將因維護而關閉。我基本上是用我的代碼如下所示創建該實例的AMI：如何從以前的EC2實例的AMI啓動VPC中的EC2實例的完全相同的副本

import boto.ec2 
import time 
import sys 
conn = boto.ec2.connect_to_region("ap-southeast-1") 

image_id = conn.create_image(sys.argv[1], "nits", description="Testing", no_reboot=True, block_device_mapping=None, dry_run=False) 
image = conn.get_all_images(image_ids=[image_id])[0] 

while image.state != 'available': 
    time.sleep(10) 
    image.update() 
    print "The image is being Created, Please wait!! state:%s" % (image.state) 

if image.state == 'available': 
    print "AMI CREATED SUCCESSFULLY with AMI id = %s" % image_id 
else: 
    print "Something Went Wrong!!"

上述腳本工作正常，並創建我提供作爲系統參數的實例的AMI。我需要啓動實例「A」的EXACT SAME REPLICA，即需要啓動的實例需要具有相同的VPC，SEC組，鍵名等。我想我需要存儲實例A的在變量的詳細信息，然後利用它們來從AMI或類似的東西推出一個新的實例..

PS：該follwing代碼有助於獲得實例A的細節：

reservations=conn.get_all_instances(sys.argv[1]) 
instances = [i for r in reservations for i in r.instances] 
for i in instances: 
    print(i.__dict__)

下面的代碼將基本上採用您將提供實例id的系統的ami，然後它提取現有系統的詳細信息，並提供新的複製系統

from boto.regioninfo import * 
from boto.ec2.connection import EC2Connection 

# Enter Instance ID here for which you want replication 
instance_id = 'i-XXXXXXXX' 

# AWS connect info 
aws_access_key_id='########## AWS Access Key ############' 
aws_secret_access_key='########### AWS Secret Key ############' 
region_name='ap-southeast-1' 
region_ec2_endpoint='ec2.ap-southeast-1.amazonaws.com' 

# Connect EC2 
aws_region = RegionInfo(name=region_name, endpoint=region_endpoint) 
conn = EC2Connection(aws_access_key_id,aws_secret_access_key,region=aws_region) 

# create ami 
print "Step 1 : Creating ami" 
ami_id = conn.create_image(instance_id,"testami",no_reboot=True) 
ami_status = "Pending" 
print "ami is being launched " + ami_id 

# check_ami_status 
image = conn.get_image(ami_id) 
while image.state == "pending": 
    time.sleep(10) 
    image = conn.get_image(ami_id) 
    print "ami is in pending state, waiting for 10 sec before next check" 

image = conn.get_image(ami_id) 
print "Image is now " + image.state 

reservations = conn.get_all_instances(instance_ids=[instance_id]) 
instances = [i for r in reservations for i in r.instances] 
for i in instances: 
    key_name = i.key_name 
    security_group = [] 
    for each in i.groups: 
     security_group.append(each.id) 
    instance_type = i.instance_type 
    subnet_name = i.subnet_id 
    vpc_id = i.vpc_id 
    reserve = conn.run_instances(image_id=ami_id,subnet_id=subnet_name ,key_name=key_name,instance_type=instance_type,security_group_ids =security_group) 
    print "new replica system id is " + reserve.instances[0].id

<？XML版本= 「1.0」編碼= 「UTF-8」？> InvalidParameterCombination參數組名不能與參數子網 5242ae3a-03EA-491C-a230-5d86afcc3870使用我需要在VPC中做到這一點 –

Nishant嘗試更新/編輯答案，我們需要一個sg_ids數組，早些時候它是一個對象數組。 – padmakarojha

我試圖用了硬編碼SG名稱：實例= [我當r在預訂我在r.instances] 因爲我在實例： KEY_NAME = i.key_name ＃security_group = 「SG-f05ee295」 #I .groups INSTANCE_TYPE = i.instance_type ＃打印security_group [0] ＃子網名稱= i.subnet_id 儲備= conn.run_instances（image_id = ami_id，KEY_NAME = KEY_NAME，INSTANCE_TYPE = INSTANCE_TYPE，security_group_ids = [ 'SG-f05ee295'] ） print「new replica system id is」+ reserve.instances [0] .id 仍然說我無法使用VPC子羣進行非VPC啓動 –
