python-azviz 1.1.0

Azure resource topology visualization tool - Python implementation inspired by the PowerShell AzViz module

Python AzViz

A modern Python implementation for automatically generating Azure resource topology diagrams, inspired by the PowerShell AzViz module.

Overview

Python AzViz generates visual diagrams of Azure Resource Groups and their dependencies by:

• Discovering Azure resources using Azure Management APIs
• Mapping resource relationships and dependencies
• Creating graph visualizations using NetworkX and Graphviz
• Supporting multiple themes and output formats

Features

• Azure Resource Discovery: Automatically finds resources and dependencies
• Subscription Flexibility: Support for both subscription IDs and names
• Network Topology Mapping: Maps VNets, subnets, and network relationships
• VM Power State Visualization: Shows running/stopped status with color coding
• Visual Themes: Light, dark, and neon color schemes
• Multiple Formats: PNG, SVG, and interactive HTML output support
• Flexible Filtering: Include/exclude specific resource types
• Icon Integration: 56+ Azure service icons for visual clarity
• Hybrid Layout: Horizontal resource groups with vertical resource stacking
• Advanced Dependencies: SSH keys, managed identities, gallery hierarchies, DNS zones
• Private Link Support: Visualizes Private Endpoints and Private Link Services
• Cross-Resource Group: Discovers dependencies across resource groups
• Storage Account Relationships: Connects VMs to storage accounts and diagnostics

Installation

Prerequisites

• Python 3.8+
• Graphviz installed on your system
• Azure CLI or Azure credentials configured

Install Graphviz

Ubuntu/Debian:

sudo apt-get install graphviz

macOS:

brew install graphviz

Windows: Download from https://graphviz.org/download/

Option 1: Install Python AzViz

pip install python-azviz

Option 2: Run Directly from Source

# Clone the repository
git clone https://github.com/rut31337/python-azviz.git
cd python-azviz

# Install dependencies
pip install -r requirements.txt

# Run directly using wrapper script
python azviz.py --help
python azviz.py export --resource-group my-rg
python azviz.py list-rg

Option 3: Development Installation

# Install in editable mode for development
pip install -e .
python-azviz --help

Quick Start

from azviz import AzViz

# Initialize with Azure credentials
viz = AzViz()

# Generate diagram for all resource groups
viz.export_diagram(
    resource_group=[],  # Empty list = all RGs
    output_file="all-resources.png",
    theme="light"
)

# Generate diagram for specific resource group
viz.export_diagram(
    resource_group="my-resource-group",
    output_file="my-diagram.png",
    theme="light"
)

CLI Usage

# Diagram all resource groups in subscription
python-azviz export --output all-resources.png

# Basic usage for specific resource group
python-azviz export --resource-group my-rg --output diagram.png

# With custom theme and format
python-azviz export --resource-group my-rg --theme dark --format svg --output diagram.svg

# Interactive HTML output
python-azviz export --resource-group my-rg --format html --output diagram.html

# Multiple resource groups
python-azviz export -g rg1 -g rg2 -g rg3 --output multi-rg.png

# Using subscription by name instead of ID
python-azviz export --subscription "My Production Subscription" --output prod.png

# Using subscription by ID
python-azviz export --subscription "12345678-1234-1234-1234-123456789012" --output prod.png

# Verbose output for debugging (shows Graphviz warnings)
python-azviz export --verbose --resource-group my-rg --output diagram.png
python-azviz export -v --resource-group my-rg --output diagram.png

# List resource groups in specific subscription
python-azviz list-rg --subscription "My Dev Subscription"

# Preview resources before generating diagram
python-azviz preview my-rg --subscription "My Test Subscription"

Configuration

Subscription Selection

Python AzViz supports flexible subscription targeting:

• By Name: --subscription "My Production Subscription"
• By ID: --subscription "12345678-1234-1234-1234-123456789012"
• Partial Matching: --subscription "Production" (must be unique)
• Auto-detection: Uses first available subscription if not specified

Authentication

Python AzViz supports multiple authentication methods:

• Azure CLI (az login)
• Environment variables
• Managed Identity
• Service Principal

Themes

• light: Light background with dark text
• dark: Dark background with light text
• neon: High-contrast neon colors

Output Formats

• png: Portable Network Graphics
• svg: Scalable Vector Graphics
• html: Interactive HTML with zoom, pan, and drag capabilities

Verbose Output

• Normal mode: Clean output with Graphviz warnings suppressed
• Verbose mode (--verbose or -v): Shows all debug information including Graphviz warnings and processing details

Supported Azure Resources

Python AzViz automatically discovers and visualizes these Azure resource types with proper relationships:

Compute

• Virtual Machines (with power state visualization)
• Virtual Machine Scale Sets
• SSH Public Keys
• Azure Compute Galleries, Images, and Versions

Network

• Virtual Networks and Subnets
• Network Interfaces
• Public IP Addresses
• Load Balancers
• Network Security Groups
• Route Tables
• Private Endpoints
• Private Link Services
• DNS Zones (Public and Private)
• Private DNS Zones and VNet Links

Storage

• Storage Accounts (with VM diagnostic relationships)
• Managed Disks

Identity

• User-Assigned Managed Identities

Container

• Azure Red Hat OpenShift Clusters
• Azure Kubernetes Service Clusters

Other

• Resource Groups (as containers)
• Cross-resource group dependencies
• Internet connectivity visualization

Examples

See the examples/ directory for more usage examples.

Migration from PowerShell AzViz

Python AzViz maintains compatibility with the original PowerShell version:

• Same parameter names and behavior
• Identical output formats and themes
• Compatible icon system
