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:
1
[default]
2
            aws_access_key_id = <id>
3
            aws_secret_access_key = <secretKey>
Copied!
Default region in file .aws/config:
1
[default]
2
            region=us-east-1
Copied!
Use the address to access Object Storage s3.coldstack.io.
