python调用aws接口添加安全组策略
介绍:1.aws安全组策略：协议、端口、流入流量、流出流量
2.aws 控制python库：boto3，需先安装。
3.脚本作用：获取本地外网IP-----》添加到指定安全组
代码：
#!/usr/bin/env python
#coding:utf-8
import re
import urllib2
import datetime
import boto3
from botocore.exceptions import ClientError
def get_ip():
# 获取外网IP
url = 'https://www.ipip.net/'
html = urllib2.urlopen(url).read()
ips = re.findall('\d+\.\d+\.\d+\.\d+',html)
ips = list(set(ips))
ip = ''
for item in ips:
if item != '8.8.8.8':
ip = item
break
return ip
d_port = 11230 # 目标端口
group_id = 'sg-xxxxxxx' # 要操作的安全组id
client = boto3.client('ec2',
region_name='ap-south-1', # 安全组所属区域
aws_access_key_id='xxxxxxxxxxx', #IAM账号id
aws_secret_access_key='xxxxxxxxxxx') #IAM账号key
now = datetime.datetime.now().strftime('%m-%d_%H:%M:%S')
my_ip =get_ip()
if my_ip is not None:
my_ip = my_ip + "/32"
# print my_ip
r_ip = []
res = client.describe_security_groups(GroupIds=)
for item in res['SecurityGroups']['IpPermissions']:
if item['FromPort'] == d_port:
for iprange in item['IpRanges']:
r_ip.append(iprange['CidrIp'])
# print r_ip
if my_ip not in r_ip:
try:
data = client.authorize_security_group_ingress(
GroupId = group_id,
IpPermissions=[{
'IpProtocol': 'tcp',
'FromPort':d_port,
'ToPort':d_port,
'IpRanges':[{'CidrIp':my_ip,'Description':now}]
}]
)
print "Add %s successful..."%my_ip
except ClientError as e:
print e
