How to initialize a boto3 client using credentials from vault

This task outlines the process of initializing a Boto3 client in Python using credentials securely retrieved from a vault, employing the _get_creds() function.

cred_label = 'myAppAwsCredentials'
creds = _get_creds(cred_label)['creds']
access_key = creds['username']
secret_key = creds['password']

It focuses on establishing a secure method to access AWS services by fetching the necessary AWS credentials (access key and secret key) from a secure vault, ensuring best practices in security and credential management are followed.

aws_service_name_client = boto3.client(
'aws_service_name',
aws_access_key_id=access_key,
aws_secret_access_key=secret_key,
region_name=region_name
)

Input Parameters for Boto3 Client Initialization:

• cred_label (String): An identifier used to retrieve specific AWS credentials from the vault.
• region_name (String): The AWS region where the service (DynamoDB, in this case) is located. This parameter is crucial for directing the Boto3 client to the correct regional endpoint.
• access_key (String): The AWS access key ID retrieved from the vault. It is used to authenticate the Boto3 client with AWS.
• secret_key (String): The AWS secret access key retrieved from the vault. Along with the access key, it forms the credentials for AWS authentication.
