S3 Connection timeout when using boto3

Question

I use boto3 to work with S3. If my application cannot reach S3 due to a network problem, the connection will hang until it ends. I would like to set a lower connection timeout. I met this PR for a botocore that allows you to set a timeout:

$ sudo iptables -A OUTPUT -p tcp --dport 443 -j DROP

from botocore.client import Config
import boto3

config = Config(connect_timeout=5, read_timeout=5)

s3 = boto3.client('s3', config=config)

s3.head_bucket(Bucket='my-s3-bucket') 

This calls ConnectTimeout, but there is still too much to fix the error:

ConnectTimeout: HTTPSConnectionPool(host='my-s3-bucket.s3.amazonaws.com', port=443): Max retries exceeded with url: / (Caused by ConnectTimeoutError(<botocore.awsrequest.AWSHTTPSConnection object at 0x2ad5dd0>, 'Connection to my-s3-bucket.s3.amazonaws.com timed out. (connect timeout=5)'))

Setting connection and read timeouts does not affect how quickly the connection responds.

Answer 1

, boto3 . :

config = Config(connect_timeout=5, retries={'max_attempts': 0})

Answer 2

- ? , boto.

boto3:

import boto3
from botocore.exceptions import ClientError
import re
from io import BytesIO
import gzip
import datetime
import dateutil.parser as dparser
from datetime import datetime
import tarfile
import requests
import sys
from awsglue.transforms import *
from awsglue.utils import getResolvedOptions
from pyspark.context import SparkContext
from awsglue.context import GlueContext
from awsglue.job import Job

## Needed glue stuff
sc = SparkContext()
glueContext = GlueContext(sc)
spark = glueContext.spark_session
job = Job(glueContext)

## 
## currently this will run for everything that is in the staging directory         of omniture

# set needed parms
myProfileName = 'MyDataLake'
dhiBucket = 'data-lake'
#create boto3 session
try:    
    session = boto3.Session(aws_access_key_id='aaaaaaaaaaaa', aws_secret_access_key='abcdefghijklmnopqrstuvwxyz', region_name='us-east-    1')aws_session_token=None, region_name=None, botocore_session=None
s3 = session.resource('s3') #establish connection to s3
except Exception as conne:
    print ("Unable to connect:  " + str(conne))
    errtxt = requests.post("https://errorcapturesite", data=    {'message':'Unable to connect to : ' + myProfileName,     'notify':True,'color':'red'})
    print(errtxt.text) 
    exit()
