boto3 and boto

1. Create a directory to store the authentication data in and navigate to it:

   For macOS and Linux:

   mkdir ~/.aws/
   

   For Windows:

   mkdir C:\Users\<username>\.aws\
   

2. In the .aws directory, create a file named credentials with credentials for Object Storage and copy the following data into it:

   [default]
   aws_access_key_id = <static_key_ID>
   aws_secret_access_key = <secret_key>
   

3. Create a file named config with the default region settings and copy the following information to it:

   [default]
   region = ru-central1
   endpoint_url = https://storage.yandexcloud.net
   

   Note

   Some apps designed to work with Amazon S3 do not allow you to specify the region; this is why Object Storage may also accept the us-east-1 value.

To access Object Storage, use the https://storage.yandexcloud.net endpoint.
