Prowler Provider

When to Use

Use this skill when:

• Adding a new cloud provider to Prowler
• Adding a new service to an existing provider
• Understanding the provider architecture pattern

Provider Architecture Pattern

Every provider MUST follow this structure:

prowler/providers/{provider}/
├── __init__.py
├── {provider}_provider.py      # Main provider class
├── models.py                   # Provider-specific models
├── config.py                   # Provider configuration
├── exceptions/                 # Provider-specific exceptions
├── lib/
│   ├── service/               # Base service class
│   ├── arguments/             # CLI arguments parser
│   └── mutelist/              # Mutelist functionality
└── services/
    └── {service}/
        ├── {service}_service.py   # Resource fetcher
        ├── {service}_client.py    # Python singleton instance
        └── {check_name}/          # Individual checks
            ├── {check_name}.py
            └── {check_name}.metadata.json

Provider Class Template

from prowler.providers.common.provider import Provider

class {Provider}Provider(Provider):
    """Provider class for {Provider} cloud platform."""

    def __init__(self, arguments):
        super().__init__(arguments)
        self.session = self._setup_session(arguments)
        self.regions = self._get_regions()

    def _setup_session(self, arguments):
        """Provider-specific authentication."""
        # Implement credential handling
        pass

    def _get_regions(self):
        """Get available regions for provider."""
        # Return list of regions
        pass

Service Class Template

from prowler.providers.{provider}.lib.service.service import {Provider}Service

class {Service}({Provider}Service):
    """Service class for {service} resources."""

    def __init__(self, provider):
        super().__init__(provider)
        self.{resources} = []
        self._fetch_{resources}()

    def _fetch_{resources}(self):
        """Fetch {resource} data from API."""
        try:
            response = self.client.list_{resources}()
            for item in response:
                self.{resources}.append(
                    {Resource}(
                        id=item["id"],
                        name=item["name"],
                        region=item.get("region"),
                    )
                )
        except Exception as e:
            logger.error(f"Error fetching {resources}: {e}")

Service Client Template

from prowler.providers.{provider}.services.{service}.{service}_service import {Service}

{service}_client = {Service}
