Python SDK (boto)

boto3 and boto
​boto3 and boto are development kits (SDKs) for the Python 2.x and 3.x programming languages. SDKs are designed to work with AWS services.
Preparation for work
1.Create a service account .
2.Assign a role to a service account .
3.Create a static access key .
Installation
To install boto, follow the instructions in the developer's repository: boto3 , boto .
Customization
To configure, create configuration files in your home directory and specify in them:
Static key in file .aws/credentials:
[default]
            aws_access_key_id = <id>
            aws_secret_access_key = <secretKey>
Default region in file .aws/config:
[default]
            region=us-east-1
Use the address to access Object Storage s3.coldstack.io.
Example
boto3
boto
#!/usr/bin/env python
#-*- coding: utf-8 -*-
import boto3
session = boto3.session.Session()
s3 = session.client(
    service_name='s3',
    endpoint_url='https://s3.coldstack.io'
)
​
# Uploading objects to the bucket
​
## From a string
s3.put_object(Bucket='bucket-name', Key='object_name', Body='TEST', StorageClass='COLD')
​
## From a file
s3.upload_file('this_script.py', 'bucket-name', 'py_script.py')
s3.upload_file('this_script.py', 'bucket-name', 'script/py_script.py')
​
# Get a list of objects in bucket
for key in s3.list_objects(Bucket='bucket-name')['Contents']:
    print(key['Key'])
​
# Download an object and print the contents to the console
get_object_response = s3.get_object(Bucket='bucket-name',Key='py_script.py')
print(get_object_response['Body'].read())
#!/usr/bin/env python
#-*- coding: utf-8 -*-
import os
from boto.s3.key import Key
from boto.s3.connection import S3Connection
os.environ['S3_USE_SIGV4'] = 'True'
conn = S3Connection(
    host='s3.coldstack.io'
)
conn.auth_region_name = 'us-east-1'
​
# Создать новый бакет
conn.create_bucket('bucket-name')
bucket = conn.get_bucket('bucket-name')
​
# Загрузить объекты в бакет
​
## Из строки
bucket.new_key('test-string').set_contents_from_string('TEST')
​
## Из файла
file_key_1 = Key(bucket)
file_key_1.key = 'py_script.py'
file_key_1.set_contents_from_filename('this_script.py')
file_key_2 = Key(bucket)
file_key_2.key = 'script/py_script.py'
file_key_2.set_contents_from_filename('this_script.py')
​
# Получить список объектов в бакете
keys_list=bucket.list()
for key in keys_list:
    print key.key
​
# Удалить несколько объектов
response = bucket.delete_keys(['test-string', 'py_script.py'])
​
# Получить объект
key = bucket.get_key('script/py_script.py')
print key.get_contents_as_string()
