2. Assign a role to a service account .

3. Create a static access key .

Installation

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

#!/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())
