🚀 InvenTag Quick Start Guide

Get up and running with InvenTag in minutes!

Prerequisites

  • Python 3.8+
  • AWS CLI configured with appropriate permissions
  • Required Python packages (install with pip install -r requirements.txt)

Basic Usage

1. Simple BOM Generation

Generate a basic Excel BOM for your default AWS account with optimized discovery:

# Unix/Linux/macOS (auto-detects python3/python)
./inventag.sh --create-excel

# Windows (auto-detects python3/python/py)
inventag.bat --create-excel

# Direct Python (use python3 if available)
python3 -m inventag_cli --create-excel

✨ Enhanced Performance: InvenTag automatically uses the optimized discovery system for 3-4x faster resource discovery with better service coverage.

2. Multi-Format Output

Generate Excel, Word, and Google Docs reports:

# Excel and Word documents (scripts auto-detect Python)
./inventag.sh --create-excel --create-word --verbose

# All formats including Google Docs (requires Google API credentials)
./inventag.sh --create-excel --create-word --create-google-docs --verbose

3. Multi-Account Setup

Create an accounts configuration file:

{
"accounts": [
{
"account_id": "123456789012",
"account_name": "Global Production",
"profile_name": "prod-profile",
"regions": ["us-east-1", "us-west-2", "ap-southeast-1", "eu-west-1"]
},
{
"account_id": "123456789013",
"account_name": "APAC Development",
"profile_name": "dev-profile",
"regions": ["ap-southeast-1", "ap-north-1", "ap-south-1"]
},
{
"account_id": "123456789014",
"account_name": "All Regions Account",
"profile_name": "global-profile",
"regions": []
}
]
}

Note: Empty regions array means scan all available AWS regions (default behavior).

Then run:

./inventag.sh --accounts-file accounts.json --create-excel

4. Multi-Region Selection

Specify regions to scan across all accounts:

# Scan specific regions globally
./inventag.sh --create-excel \
--account-regions us-east-1,us-west-2,ap-southeast-1,ap-north-1

# Asia-Pacific regions only
./inventag.sh --create-excel \
--account-regions ap-southeast-1,ap-southeast-2,ap-north-1,ap-south-1

# European regions with GDPR compliance
./inventag.sh --create-excel \
--account-regions eu-west-1,eu-west-2,eu-central-1 \
--compliance-standard gdpr

# All regions (default behavior)
./inventag.sh --create-excel --verbose

5. Advanced Analysis

Enable comprehensive analysis features:

./inventag.sh \
--create-excel \
--enable-network-analysis \
--enable-security-analysis \
--enable-cost-analysis \
--verbose

6. Production Deployment

For production use with S3 upload and security features:

./inventag.sh \
--accounts-file accounts.json \
--create-excel --create-word \
--enable-network-analysis --enable-security-analysis --enable-cost-analysis \
--s3-bucket my-reports-bucket \
--s3-key-prefix bom-reports/$(date +%Y-%m-%d)/ \
--compliance-standard soc2 \
--enable-production-safety --security-validation \
--audit-output security-audit.json \
--verbose

Configuration Examples

Service Descriptions

Customize service descriptions in your BOM:

# service-descriptions.yaml
EC2:
default_description: "Amazon Elastic Compute Cloud - Virtual servers"
resource_types:
Instance: "Virtual machine instances"
Volume: "Block storage volumes"

S3:
default_description: "Amazon Simple Storage Service - Object storage"
resource_types:
Bucket: "Storage containers"

Use with:

# Using the provided example
./inventag.sh --create-excel --service-descriptions config/defaults/services/service_descriptions_example.yaml

# Or create your own
./inventag.sh --create-excel --service-descriptions service-descriptions.yaml

Tag Mappings

Map AWS tags to custom BOM columns:

# tag-mappings.yaml
"Environment":
column_name: "Environment"
default_value: "Unknown"

"inventag:owner":
column_name: "Resource Owner"
default_value: "Unassigned"

Use with:

# Using the provided example
./inventag.sh --create-excel --tag-mappings config/defaults/mappings/tag_to_column_mappings_example.yaml

# Or create your own
./inventag.sh --create-excel --tag-mappings tag-mappings.yaml

Common Commands

# Validate configuration
./inventag.sh --accounts-file accounts.json --validate-config

# Validate credentials
./inventag.sh --accounts-file accounts.json --validate-credentials

# Debug mode
./inventag.sh --create-excel --debug --log-file debug.log

# Interactive account setup with Google Docs
./inventag.sh --accounts-prompt --create-excel --create-google-docs

# Cross-account role assumption
./inventag.sh --cross-account-role InvenTagRole --create-excel

# CI/CD integration with security validation
./inventag.sh \
--accounts-file $ACCOUNTS_CONFIG \
--create-excel \
--s3-bucket $REPORTS_BUCKET \
--max-concurrent-accounts 8 \
--security-validation --compliance-standard soc2

Output Files

InvenTag generates files in the bom_output directory (or your specified output directory):

  • AWS_BOM_YYYYMMDD_HHMMSS.xlsx - Excel workbook with multiple sheets
  • AWS_BOM_YYYYMMDD_HHMMSS.docx - Professional Word document
  • state_YYYYMMDD_HHMMSS.json - State file for change tracking

Performance Features

InvenTag includes an Optimized Discovery System that provides significant performance improvements:

Key Performance Benefits

FeatureBenefit
3-4x Faster DiscoveryParallel processing and service-specific patterns
Enhanced Service CoverageBetter detection of CloudFront, IAM, Route53, S3, Lambda
Higher Quality Results98% of resources achieve high confidence scores
Intelligent Field MappingService-specific extraction for better accuracy

Performance Tips

# Maximum performance with parallel processing
./inventag.sh --create-excel --max-concurrent-accounts 6

# Focus on specific services for faster processing
./inventag.sh --create-excel --service-filters ec2,s3,rds,lambda

# Single region for fastest discovery
./inventag.sh --create-excel --account-regions us-east-1

The optimized discovery system is enabled by default and requires no additional configuration.
