Prowler enables automated provisioning of multiple cloud providers through the Bulk Provider Provisioning tool. This approach streamlines the onboarding process for organizations managing numerous cloud accounts, subscriptions, and projects across AWS, Azure, GCP, Kubernetes, Microsoft 365, and GitHub. The tool is available in the Prowler repository at: util/prowler-bulk-provisioning

​
Overview

The Bulk Provider Provisioning tool automates the creation of cloud providers in Prowler App or Prowler Cloud by:
  • Reading provider configurations from YAML files
  • Creating providers with appropriate authentication credentials
  • Testing connections to verify successful authentication
  • Processing multiple providers concurrently for efficiency
Using AWS Organizations? For organizations with many AWS accounts, use the automated AWS Organizations Bulk Provisioning tool to automatically discover and generate configuration for all accounts in your organization.

​
Prerequisites

​
Requirements

  • Python 3.7 or higher
  • Prowler API key (from Prowler Cloud or self-hosted Prowler App)
  • Authentication credentials for target cloud providers

​
Installation

Clone the repository and install the required dependencies: 
git clone https://github.com/prowler-cloud/prowler.git
cd prowler/util/prowler-bulk-provisioning
pip install -r requirements.txt

​
Authentication Setup

Configure your Prowler API key: 
export PROWLER_API_KEY="pk_example-api-key"
To create an API key:
  1. Log in to Prowler Cloud or Prowler App
  2. Click Profile → Account
  3. Click Create API Key
  4. Provide a descriptive name and optionally set an expiration date
  5. Copy the generated API key (it will only be shown once)
For detailed instructions, see: Prowler App API Keys

​
Configuration File Structure

Create a YAML file listing your cloud providers and credentials: 
# providers.yaml
- provider: aws
  uid: "123456789012"              # AWS Account ID
  alias: "production-account"
  auth_method: role
  credentials:
    role_arn: "arn:aws:iam::123456789012:role/ProwlerScanRole"
    external_id: "prowler-external-id"

- provider: azure
  uid: "00000000-1111-2222-3333-444444444444"  # Subscription ID
  alias: "azure-production"
  auth_method: service_principal
  credentials:
    tenant_id: "aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee"
    client_id: "ffffffff-1111-2222-3333-444444444444"
    client_secret: "your-client-secret"

- provider: gcp
  uid: "my-gcp-project"            # Project ID
  alias: "gcp-production"
  auth_method: service_account
  credentials:
    service_account_key_json_path: "./service-account.json"

​
Running the Bulk Provisioning Tool

​
Basic Usage

To provision all providers from your configuration file: 
python prowler_bulk_provisioning.py providers.yaml
The tool automatically tests each provider connection after creation (enabled by default).

​
Dry Run Mode

Test your configuration without making API calls: 
python prowler_bulk_provisioning.py providers.yaml --dry-run

​
Skip Connection Testing

To provision providers without testing connections: 
python prowler_bulk_provisioning.py providers.yaml --test-provider false

​
Test Existing Providers Only

To verify connections for already provisioned providers: 
python prowler_bulk_provisioning.py providers.yaml --test-provider-only

​

  alias: "aws-development"
  auth_method: credentials
  credentials:
    access_key_id: "AKIA..."
    secret_access_key: "..."
    session_token: "..."  # optional for temporary credentials

​

  alias: "gcp-production"
  auth_method: service_account
  credentials:
    service_account_key_json_path: "/path/to/key.json"

​
Using OAuth2 Credentials

Bulk Provider Management

​
Deleting Multiple Providers

To remove all providers from your Prowler account: 
python nuke_providers.py --confirm
Filter deletions by provider type: 
python nuke_providers.py --confirm --filter-provider aws
Filter deletions by alias pattern: 
python nuke_providers.py --confirm --filter-alias "test-*"

​
Configuration File Format

The tool uses YAML format for provider configuration files. Each provider entry requires:
  • provider: The cloud provider type (aws, azure, gcp, kubernetes, m365, github)
  • uid: Unique identifier for the provider (account ID, subscription ID, project ID, etc.)
  • alias: A friendly name for the provider
  • auth_method: Authentication method to use
  • credentials: Authentication credentials specific to the provider and method
Example YAML structure: 
- provider: aws
  uid: "123456789012"
  alias: "production"
  auth_method: role
  credentials:
    role_arn: "arn:aws:iam::123456789012:role/ProwlerScan"

​

​
Troubleshooting

​
Invalid API Key

Error: 401 Unauthorized
Solution: Verify your PROWLER_API_KEY environment variable or --api-key parameter

​
Network Timeouts

Error: Connection timeout
Solution: Increase timeout with --timeout 120

​
Provider Already Exists

Error: Provider with this UID already exists
Solution: Use different UID or delete existing provider first

​
Authentication Failures

Connection test: Not connected
Solution: Verify credentials and IAM permissions
