📦 Installation

# Install with pip
pip install azpaddypy

# Install with uv (recommended)
uv add azpaddypy

🚀 Quick Start

Simple Usage (Direct Imports)

from azpaddypy import logger, identity, keyvault, storage_account

# Use logger for application logging
logger.info("Application started")

# Use identity for Azure authentication  
token = identity.get_token("https://management.azure.com/.default")

# Access secrets from Key Vault
secret_value = keyvault.get_secret("my-secret")

# Use storage services
blob_client = storage_account.blob_service_client

Builder Pattern Usage (Recommended)

from azpaddypy.builder import (
    ConfigurationSetupBuilder, 
    AzureManagementBuilder, 
    AzureResourceBuilder
)

# 1. Setup environment configuration
env_config = (
    ConfigurationSetupBuilder()
    .with_local_env_management()      # Load .env files (FIRST)
    .with_environment_detection()     # Detect Docker vs local
    .with_service_configuration()     # Parse service settings
    .with_logging_configuration()     # Setup logging
    .with_identity_configuration()    # Configure authentication
    .build()
)

# 2. Build management services (logger, identity, key vault)
management = (
    AzureManagementBuilder(env_config)
    .with_logger()
    .with_identity() 
    .with_keyvault(vault_url="https://my-vault.vault.azure.net/")
    .build()
)

# 3. Build resource services (storage, etc.)
resources = (
    AzureResourceBuilder(management, env_config)
    .with_storage(account_url="https://mystorageaccount.blob.core.windows.net/")
    .build()
)

# 4. Use the configured services
management.logger.info("Services configured successfully")
secret = management.keyvault.get_secret("database-password")
blob_client = resources.storage_account.blob_service_client

🔧 Configuration

Environment Variables

Create a .env file or set environment variables:

# Required: Key Vault Configuration
key_vault_uri=https://my-vault.vault.azure.net/
head_key_vault_uri=https://my-admin-vault.vault.azure.net/

# Required: Storage Configuration  
STORAGE_ACCOUNT_URL=https://mystorageaccount.blob.core.windows.net/

# Optional: Service Configuration
REFLECTION_NAME=my-application
REFLECTION_KIND=functionapp
SERVICE_VERSION=1.0.0

# Optional: Logging Configuration
LOGGER_LOG_LEVEL=INFO
APPLICATIONINSIGHTS_CONNECTION_STRING=InstrumentationKey=...

# Optional: Identity Configuration
IDENTITY_ENABLE_TOKEN_CACHE=true
IDENTITY_ALLOW_UNENCRYPTED_STORAGE=true

# Optional: Feature Toggles
KEYVAULT_ENABLE_SECRETS=true
KEYVAULT_ENABLE_KEYS=false
KEYVAULT_ENABLE_CERTIFICATES=false

STORAGE_ENABLE_BLOB=true
STORAGE_ENABLE_FILE=true  
STORAGE_ENABLE_QUEUE=true

Azure Authentication

AzPaddyPy supports multiple authentication methods automatically:

Local Development:

# Option 1: Azure CLI (recommended)
az login

# Option 2: Environment variables
export AZURE_CLIENT_ID=your-client-id
export AZURE_TENANT_ID=your-tenant-id  
export AZURE_CLIENT_SECRET=your-client-secret

Production (Azure):

• Managed Identity (automatically detected)
• Service Principal (via environment variables)

📚 Usage Examples

Working with Key Vault

from azpaddypy.builder import AzureManagementBuilder, ConfigurationSetupBuilder

# Setup
env_config = ConfigurationSetupBuilder().with_local_env_management().build()
management = (
    AzureManagementBuilder(env_config)
    .with_identity()
    .with_keyvault(name="primary", vault_url="https://my-vault.vault.azure.net/")
    .with_keyvault(name="admin", vault_url="https://my-admin-vault.vault.azure.net/")
    .build()
)

# Access secrets
database_password = management.keyvaults["primary"].get_secret("database-password")
admin_key = management.keyvaults["admin"].get_secret("admin-api-key")

# Set secrets
management.keyvaults["primary"].set_secret("new-secret", "secret-value")

Working with Storage

from azpaddypy.builder import AzureResourceBuilder

# Build storage configuration
resources = (
    AzureResourceBuilder(management, env_config)
    .with_storage(
        name="main",
        account_url="https://mystorageaccount.blob.core.windows.net/",
        enable_blob=True,
        enable_file=True,
        enable_queue=True
    )
    .build()
)

# Use storage services
storage = resources.storage_accounts["main"]

# Blob operations
blob_client = storage.blob_service_client
container_client = blob_client.get_container_client("my-container")

# Upload a file
with open("local-file.txt", "rb") as data:
    container_client.upload_blob(name="remote-file.txt", data=data)

# Queue operations  
queue_client = storage.queue_service_client
queue = queue_client.get_queue_client("my-queue")
queue.send_message("Hello from azpaddypy!")

# File share operations
file_client = storage.file_service_client
share_client = file_client.get_share_client("my-share")

Advanced Logging

from azpaddypy.builder import AzureManagementBuilder

management = (
    AzureManagementBuilder(env_config)
    .with_logger(
        log_level="DEBUG",
        enable_console=True
    )
    .build()
)

logger = management.logger

# Structured logging
logger.info("User action", extra={
    "user_id": "12345",
    "action": "login",
    "ip_address": "192.168.1.1"
})

# Error logging with context
try:
    risky_operation()
except Exception as e:
    logger.error("Operation failed", extra={
        "error_type": type(e).__name__,
        "operation": "risky_operation"
    }, exc_info=True)

Environment-Specific Configuration

from azpaddypy.builder import ConfigurationSetupBuilder

# Local development configuration
local_config = {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "DATABASE_URL": "sqlite:///local.db"
}

env_config = (
    ConfigurationSetupBuilder()
    .with_local_env_management()
    .with_environment_detection()
    .with_environment_variables(
        local_config,
        in_docker=False,    # Don't apply in Docker
        in_machine=True     # Apply on local machine
    )
    .with_service_configuration()
    .build()
)

Director Patterns (Simplified Setup)

from azpaddypy.builder.directors import (
    ConfigurationSetupDirector,
    AzureManagementDirector,
    AzureResourceDirector
)

# Quick setup with sensible defaults
env_config = ConfigurationSetupDirector.build_default_config()
management = AzureManagementDirector.build_default_config(env_config)
full_config = AzureResourceDirector.build_default_config(env_config, management)

# Access services
logger = full_config.management.logger
keyvault = full_config.management.keyvault
storage = full_config.resources.storage_account

Builder Flow

1. ConfigurationSetupBuilder - Environment setup and detection
2. AzureManagementBuilder - Core management services
3. AzureResourceBuilder - Azure resource services
4. Directors - Pre-configured common patterns

🔒 Security Best Practices

Key Vault Security

# ✅ Good: Use specific vault URLs
management.with_keyvault(vault_url="https://prod-vault.vault.azure.net/")

# ❌ Avoid: Hardcoding secrets
database_password = "hardcoded-password"  # DON'T DO THIS

# ✅ Good: Retrieve from Key Vault
database_password = keyvault.get_secret("database-password")

Identity Security

# ✅ Good: Enable token caching for performance
.with_identity_configuration(
    enable_token_cache=True,
    allow_unencrypted_storage=False  # Use encrypted cache in production
)

# ✅ Good: Use Managed Identity in production
# No additional configuration needed - automatically detected

Environment Security

# ✅ Good: Environment-specific configurations
production_config = {
    "IDENTITY_ALLOW_UNENCRYPTED_STORAGE": "false",
    "LOGGER_LOG_LEVEL": "WARNING"
}

development_config = {
    "IDENTITY_ALLOW_UNENCRYPTED_STORAGE": "true", 
    "LOGGER_LOG_LEVEL": "DEBUG"
}
