Overview

The VMware vRA CLI is a comprehensive command-line interface tool designed to interact with VMware vRealize Automation environments. It provides a rich set of commands for managing service catalogs, deployments, workflows, and system configuration through a secure, authenticated API layer.

Key Architectural Principles

  1. Modular Design: Separation of concerns with distinct modules for authentication, API clients, CLI commands, and configuration management
  2. Security First: Secure credential storage, token management, and SSL/TLS communication
  3. Extensibility: Plugin-based architecture allowing for easy addition of new commands and features
  4. User Experience: Rich terminal output, multiple output formats, and comprehensive error handling
  5. Cross-Platform: Compatible across Windows, macOS, and Linux environments

Technology Stack

  • Language: Python 3.8+
  • CLI Framework: Click
  • HTTP Client: Requests with retry mechanisms
  • Authentication: Custom VMware vRA authentication flow
