Boto3 --> Modifying EC2's instance to have multiple Security Groups - python

I have a couple of Security Groups I'd like to attach to an EC2 instance.
I tried the following but failed:
sg_1 = 'sg-something'
sg_2 = 'sg-else'
response = instance.modify_attribute(Groups=sg_1, sg_2)
And something like this:
response = instance.modify_attribute(Groups=[sg_1, sg_2])
And something like this:
for sg in sg_1, sg_2:
response = instance.modify_attribute(Groups=[sg_1, sg_2])
It seems like it can only accept one sg at a time but when I pass the second one it overwrites the previous one.
Any ideas?
Thanks

This worked fine for me:
import boto3
client=boto3('ec2')
response = client.modify_instance_attribute(InstanceId='i-1234',Groups=['sg-1111','sg-2222'])
Or using the resource version:
import boto3
ec2 = boto3.resource('ec2')
instance = ec2.Instance('i-1234')
instance.modify_attribute(Groups=['sg-1111','sg-2222'])

Binance API Issue - Python

APIError(code=-2015): Invalid API-key, IP, or permissions for action
I keep getting the above issue.
I am not sure what the issue is.
I am able to access the client.get_all_tickers() command no problem but when I try to place an order or access user_data (both which require a signature) I get the error
APIError(code=-2015): Invalid API-key, IP, or permissions for action
I think the issue has something to do with the signature. I checked to see if I have the relevant permissions enabled and I do. Furthermore, I tried to create a new API key and I still go the same issue.
NOTE: I am using binance.us not binance.com because I am located in the US so I cannot make an account on binance.com
Therefore, another idea I had was to create a VPN that places me in England so I can make an account through binance.com and maybe that will work.
import time
import datetime
import json
from time import sleep
from binance.client import Client
from binance.enums import *
import sys
import requests, json, time, hashlib
import urllib3
import logging
from urllib3 import PoolManager
from binance.exceptions import BinanceAPIException, BinanceWithdrawException
r = requests.get('https://www.binance.us/en/home')
client = Client(API_key,Secret_key,tld="us")
prices = client.get_all_tickers()
#Def to get location
def crypto_location(sym):
count = 0
for i in prices:
count += 1
ticker = i.get('symbol')
if ticker == sym:
val = i.get('price')
count = count-1
return count
bitcoin_location = crypto_location('BTCUSDT')
ethereum_location = crypto_location('ETHUSDT')
stable_coin_location = crypto_location('BUSDUSDT')
bitcoin_as_BUSD_location = crypto_location('BTCBUSD')
#%% Where to quickly get bitcoin price
t_min = time.localtime().tm_min
prices = client.get_all_tickers()
bitcoin_price = prices[bitcoin_location].get('price')
print(bitcoin_price)
ethereum_price = prices[ethereum_location].get('price')
print(ethereum_price)
stable_coin_price = prices[stable_coin_location].get('price')
print(stable_coin_price)
bitcoin_as_BUSD = prices[bitcoin_as_BUSD_location].get('price')
print(bitcoin_as_BUSD)
client.session.headers.update({ 'X-MBX-APIKEY': API_key})
client.get_account()
error occurs at client.get_account()
I had the same problem, the binance APIs without any IP restrictions, expire every 90 days. I have restricted the API to my IP and it works!
Still, you're sure to find it all here:

Get elasticloadbalancers names with boto3

When I try to print the load balancers from aws I get a huge dictionary with a lot of keys, but when I'm trying to print only the 'LoadBalancerName' value I get: None, I want to print all the load balancers names in our environment how I can do it? thanks!
What I tried:
import boto3
client = boto3.client('elbv2')
elb = client.describe_load_balancers()
Name = elb.get('LoadBalancerName')
print(Name)
The way in which you were handling the response object was incorrect, and you'll need to put it in a loop if you want all the Names and not just one. What you'll you'll need is this :
import boto3
client = boto3.client('elbv2')
elb = client.describe_load_balancers()
for i in elb['LoadBalancers']:
print(i['LoadBalancerArn'])
print(i['LoadBalancerName'])
However if your still getting none as a value it would be worth double checking what region the load balancers are in as well as if you need to pass in the use of a profile too.

boto3 searching unused security groups

I am using AWS Python SDK Boto3 and I am trying to know which security groups are unused. With boto2 I did it but I do not know how to do the same with boto3.
from boto.ec2.connection import EC2Connection
from boto.ec2.regioninfo import RegionInfo
import boto.sns
import sys
import logging
from security_groups_config import config
# Get settings from config.py
aws_access_key = config['aws_access_key']
aws_secret_key = config['aws_secret_key']
ec2_region_name = config['ec2_region_name']
ec2_region_endpoint = config['ec2_region_endpoint']
region = RegionInfo(name=ec2_region_name, endpoint=ec2_region_endpoint)
if aws_access_key:
conn = EC2Connection(aws_access_key, aws_secret_key, region=region)
else:
conn = EC2Connection(region=region)
sgs = conn.get_all_security_groups()
## Searching unused SG if the instances number is 0
def search_unused_sg(event, context):
for sg in sgs:
print sg.name, len(sg.instances())
Use the power of Boto3 and Python's list comprehension and sets to get what you want in 7 lines of code:
import boto3
ec2 = boto3.resource('ec2') #You have to change this line based on how you pass AWS credentials and AWS config
sgs = list(ec2.security_groups.all())
insts = list(ec2.instances.all())
all_sgs = set([sg.group_name for sg in sgs])
all_inst_sgs = set([sg['GroupName'] for inst in insts for sg in inst.security_groups])
unused_sgs = all_sgs - all_inst_sgs
Debug information
print 'Total SGs:', len(all_sgs)
print 'SGS attached to instances:', len(all_inst_sgs)
print 'Orphaned SGs:', len(unused_sgs)
print 'Unattached SG names:', unused_sgs
Output
Total SGs: 289
SGS attached to instances: 129
Orphaned SGs: 160
Unattached SG names: set(['mysg', '...
First , I suggest you relook how boto3 deal with credential. Better use a genereic AWS credential file , so in the future when required, you can switch to IAM roles base credential or AWS STS without changing your code.
import boto3
# You should use the credential profile file
ec2 = boto3.client("ec2")
# In boto3, if you have more than 1000 entries, you need to handle the pagination
# using the NextToken parameter, which is not shown here.
all_instances = ec2.describe_instances()
all_sg = ec2.describe_security_groups()
instance_sg_set = set()
sg_set = set()
for reservation in all_instances["Reservations"] :
for instance in reservation["Instances"]:
for sg in instance["SecurityGroups"]:
instance_sg_set.add(sg["GroupName"])
for security_group in all_sg["SecurityGroups"] :
sg_set.add(security_group ["GroupName"])
idle_sg = sg_set - instance_sg_set
Note : code are not tested. Please debug it as required.
Note: If you have ASG (Autoscalling group) that are in null state (count=0), when the ASG start adding adding the security groups, then it will adopt the orphan security groups. Keep in mind you need to check for the ASG security groups also
I used an alternative approach. If we skip the credentials discussion and go back to the main question "boto3 searching unused security groups" here is an option:
You go and enumerate the resource, in my case a network interface, because if you think about it, a security group has to be associated to a resource in order to be used.
My example:
client = boto3.client('ec2', region_name=region, aws_access_key_id=newsession_id, aws_secret_access_key=newsession_key, aws_session_token=newsession_token)
response = client.describe_network_interfaces()
for i in response["NetworkInterfaces"]:
#Check if the security group is attached
if 'Attachment' in i and i['Attachment']['Status'] == 'attached':
#Create a list with the attached SGs
groups = [g['GroupId'] for g in i['Groups']]
II used the network interface resource because I needed to get public IPs for the accounts.

python django soaplib response with classmodel issue

I run a soap server in django.
Is it possible to create a soap method that returns a soaplib classmodel instance without <{method name}Response><{method name}Result> tags?
For example, here is a part of my soap server code:
# -*- coding: cp1254 -*-
from soaplib.core.service import rpc, DefinitionBase, soap
from soaplib.core.model.primitive import String, Integer, Boolean
from soaplib.core.model.clazz import Array, ClassModel
from soaplib.core import Application
from soaplib.core.server.wsgi import Application as WSGIApplication
from soaplib.core.model.binary import Attachment
class documentResponse(ClassModel):
__namespace__ = ""
msg = String
hash = String
class MyService(DefinitionBase):
__service_interface__ = "MyService"
__port_types__ = ["MyServicePortType"]
#soap(String, Attachment, String ,_returns=documentResponse,_faults=(MyServiceFaultMessage,) , _port_type="MyServicePortType" )
def sendDocument(self, fileName, binaryData, hash ):
binaryData.file_name = fileName
binaryData.save_to_file()
resp = documentResponse()
resp.msg = "Saved"
resp.hash = hash
return resp
and it responses like that:
<senv:Body>
<tns:sendDocumentResponse>
<tns:sendDocumentResult>
<hash>14a95636ddcf022fa2593c69af1a02f6</hash>
<msg>Saved</msg>
</tns:sendDocumentResult>
</tns:sendDocumentResponse>
</senv:Body>
But i need a response like this:
<senv:Body>
<ns3:documentResponse>
<hash>A694EFB083E81568A66B96FC90EEBACE</hash>
<msg>Saved</msg>
</ns3:documentResponse>
</senv:Body>
What kind of configurations should i make in order to get that second response i mentioned above ?
Thanks in advance.
I haven't used Python's SoapLib yet, but had the same problem while using .NET soap libs. Just for reference, in .NET this is done using the following decorator:
[SoapDocumentMethod(ParameterStyle=SoapParameterStyle.Bare)]
I've looked in the soaplib source, but it seems it doesn't have a similar decorator. The closest thing I've found is the _style property. As seen from the code https://github.com/soaplib/soaplib/blob/master/src/soaplib/core/service.py#L124 - when using
#soap(..., _style='document')
it doesn't append the %sResult tag, but I haven't tested this. Just try it and see if this works in the way you want it.
If it doesn't work, but you still want to get this kind of response, look at Spyne:
http://spyne.io/docs/2.10/reference/decorator.html
It is a fork from soaplib(I think) and has the _soap_body_style='bare' decorator, which I believe is what you want.

How to create a signed cloudfront URL with Python?

I would like to know how to create a signed URL for cloudfront. The current working solution is unsecured, and I would like to switch the system to secure URL's.
I have tried using Boto 2.5.2 and Django 1.4
Is there a working example on how to use the boto.cloudfront.distribution.create_signed_url method? or any other solution that works?
I have tried the following code using the BOTO 2.5.2 API
def get_signed_url():
import boto, time, pprint
from boto import cloudfront
from boto.cloudfront import distribution
AWS_ACCESS_KEY_ID = 'YOUR_AWS_ACCESS_KEY_ID'
AWS_SECRET_ACCESS_KEY = 'YOUR_AWS_SECRET_ACCESS_KEY'
KEYPAIR_ID = 'YOUR_KEYPAIR_ID'
KEYPAIR_FILE = 'YOUR_FULL_PATH_TO_FILE.pem'
CF_DISTRIBUTION_ID = 'E1V7I3IOVHUU02'
my_connection = boto.cloudfront.CloudFrontConnection(AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY)
distros = my_connection.get_all_streaming_distributions()
oai = my_connection.create_origin_access_identity('my_oai', 'An OAI for testing')
distribution_config = my_connection.get_streaming_distribution_config(CF_DISTRIBUTION_ID)
distribution_info = my_connection.get_streaming_distribution_info(CF_DISTRIBUTION_ID)
my_distro = boto.cloudfront.distribution.Distribution(connection=my_connection, config=distribution_config, domain_name=distribution_info.domain_name, id=CF_DISTRIBUTION_ID, last_modified_time=None, status='Active')
s3 = boto.connect_s3()
BUCKET_NAME = "YOUR_S3_BUCKET_NAME"
bucket = s3.get_bucket(BUCKET_NAME)
object_name = "FULL_URL_TO_MP4_ECLUDING_S3_URL_DOMAIN_NAME EG( my/path/video.mp4)"
key = bucket.get_key(object_name)
key.add_user_grant("READ", oai.s3_user_id)
SECS = 8000
OBJECT_URL = 'FULL_S3_URL_TO_FILE.mp4'
my_signed_url = my_distro.create_signed_url(OBJECT_URL, KEYPAIR_ID, expire_time=time.time() + SECS, valid_after_time=None, ip_address=None, policy_url=None, private_key_file=KEYPAIR_FILE, private_key_string=KEYPAIR_ID)
Everything seems fine until the method create_signed_url. It returns an error.
Exception Value: Only specify the private_key_file or the private_key_string not both
Omit the private_key_string:
my_signed_url = my_distro.create_signed_url(OBJECT_URL, KEYPAIR_ID,
expire_time=time.time() + SECS, private_key_file=KEYPAIR_FILE)
That parameter is used to pass the actual contents of the private key file, as a string. The comments in the source explain that only one of private_key_file or private_key_string should be passed.
You can also omit all the kwargs which are set to None, since None is the default.
