boto3 and boto

The boto3 and boto development tools offer SDKs for the Python 2.x and 3.x programming languages. The SDKs are designed for working with AWS services.

Before you start

  1. Create a service account.
  2. Assign a role to a service account.
  3. Create a static access key.

Installation

To install boto, use the instructions in the developer's repository: boto3, boto.

Configuration

To configure the SDK, create configuration files in your home folder and set the following in them:

  • The static key in the file .aws/credentials:

    [default]
                aws_access_key_id = <id>
                aws_secret_access_key = <secretKey>
    
  • The default region in the file .aws/config:

    [default]
                region=ru-central1
    

    Note

    Some apps designed to work with Amazon S3 don't let you set the region, so Object Storage also accepts the value us-east-1.

Use the storage.yandexcloud.net address to access Object Storage.

Example

#!/usr/bin/env python
#-*- coding: utf-8 -*-
import boto3
session = boto3.session.Session()
s3 = session.client(
    service_name='s3',
    endpoint_url='https://storage.yandexcloud.net'
)

# Create a new bucket
s3.create_bucket(Bucket='bucket-name')

# Uploading objects into the bucket

## From a string

## From a file
s3.upload_file('this_script.py', 'bucket-name', 'py_script.py')
