Aims to simplify and help with commonly used functions in the aws cloud data areas.

Binary Rain Helper Toolkit: AWS Cloud

binaryrain_helper_cloud_aws is a python package that aims to simplify and help with common functions in AWS Cloud areas. It builds on top of the boto3 and aws-lambda-powertools libraries and provides additional functionality to make working with AWS Cloud easier, reduces boilerplate code and provides clear error messages.

Key Functions

• get_secret_data(): retrieves secrets from AWS Secrets Manager:

  from binaryrain_helper_cloud_aws.aws import get_secret_data
  
  # Get a secret from AWS Secrets Manager
  secret = get_secret_data("my-secret")
  
  # Access secret values
  database_password = secret["password"]
  

• get_app_config(): simplifies working with AWS AppConfig:

  from binaryrain_helper_cloud_aws.aws import get_app_config
  
  # Load configuration from AWS AppConfig
  config = get_app_config(
      AppConfig_environment="Production",
      AppConfig_application="MyApp",
      AppConfig_profile="DefaultConfig"
  )
  
  # Access configuration values
  api_endpoint = config["api_endpoint"]
  

• load_file_from_s3(): provides a simple way to read data from S3:

  from binaryrain_helper_cloud_aws.aws import load_file_from_s3
  
  # Load a file from S3
  file_bytes = load_file_from_s3(
      filename="data.csv",
      s3_bucket="my-bucket"
  )
  
  # Use the file content
  print(f"File size: {len(file_bytes)} bytes")
  

• save_file_to_s3(): handles uploading files to S3 with optional encryption:

  from binaryrain_helper_cloud_aws.aws import save_file_to_s3
  
  # Save a file to S3
  save_file_to_s3(
      filename="output.json",
      s3_bucket="my-bucket",
      file_contents=json_bytes
  )
  
  # Save with server-side encryption
  save_file_to_s3(
      filename="sensitive-data.csv",
      s3_bucket="my-secure-bucket",
      file_contents=csv_bytes,
      server_side_encryption="aws:kms",
      sse_kms_key_id="arn:aws:kms:region:account:key/key-id"
  )
  

• get_s3_presigned_url_readonly(): generates presigned URLs for time-limited S3 object access:

  from binaryrain_helper_cloud_aws.aws import get_s3_presigned_url_readonly
  
  # Generate a presigned URL valid for 2 minutes
  url = get_s3_presigned_url_readonly(
      filename="report.pdf",
      s3_bucket="my-bucket"
  )
  
  # Generate a presigned URL valid for 1 hour
  long_url = get_s3_presigned_url_readonly(
      filename="large-dataset.parquet",
      s3_bucket="my-bucket",
      expires_in=3600
  )
  

Benefits

• Consistent error handling with clear messages
• Input validation for all function parameters
• Simplified authentication and access to AWS services
• Secure handling of secrets and sensitive information
• Type hints for better IDE support
