CLI tool for managing IsardVDI virtual desktops on the Gencat educational platform

Isard CLI

A Python CLI tool for managing IsardVDI virtual desktops on the Gencat educational platform (elmeuescriptori.gestioeducativa.gencat.cat). This tool provides a streamlined command-line interface for educators and administrators to manage virtual desktop environments.

Features

• Seamless Authentication: Automated SAML 2.0 flow via Azure Entra ID with session caching
• Desktop Management: Create, start, stop, delete, and list virtual desktops with detailed status information
• Template Management: Browse and select from available desktop templates with hardware specifications
• Remote Desktop Access: Connect to desktops via SSH or virt-viewer with SPICE protocol
• Windows virt-viewer Integration: Automatic installation and management of virt-viewer on Windows
• Hardware Information: View CPU and memory specifications for virtual desktops
• Session Persistence: Automatic session management and token refresh
• Rich CLI Experience: Beautiful console output with status indicators and progress bars

Installation

From PyPI (Recommended)

pip install isard

From Source

git clone https://gitlab.com/daviddemingo/isard.git
cd isard
uv sync
uv run python -m isard --help

Quick Start

Authentication

Set up your credentials using environment variables:

export GENCAT_USERNAME="[e-mail]"
export GENCAT_PASSWORD="your-password"

Or create a .env file in your working directory:

GENCAT_USERNAME=[e-mail]
GENCAT_PASSWORD=your-password

Basic Usage

# Login and display session information
isard login

# Show version
isard version

# List all virtual desktops
isard list

# List desktops with hardware specifications
isard list --hardware

# Browse available templates
isard template

# Browse templates with hardware info
isard template --hardware

# Create a new desktop
isard create "My Desktop"

# Create desktop from specific template
isard create "My Desktop" --template "Ubuntu 22.04"

# Start a desktop
isard start "Desktop Name"

# Start a desktop and wait for it to be ready
isard start "Desktop Name" --wait --timeout 300

# Stop a desktop
isard stop "Desktop Name"

# Delete a desktop (move to trash - recoverable)
isard delete "Desktop Name"

# Permanently delete a desktop (irreversible)
isard delete "Desktop Name" --permanent

# Delete with confirmation skip
isard delete "Desktop Name" --yes

# Open desktop in virt-viewer
isard view "Desktop Name"

# Open desktop with auto-start if stopped
isard view "Desktop Name" --start

# SSH into a desktop
isard ssh "Desktop Name"

# SSH with auto-start if desktop is stopped
isard ssh "Desktop Name" --start

# Logout (clear cached sessions)
isard logout

Commands

Command	Description	Options

start <name>	Start a stopped desktop	--wait/-w, --timeout
stop <name>	Stop a running desktop	--wait/-w, --timeout
delete <name>	Delete desktop (trash or permanent)	--permanent, --yes/-y
view <name>	Open desktop in virt-viewer via SPICE	--start, --install/--no-install
ssh <name>	SSH into desktop via bastion	--start, --user/-l, --identity/-i, --dry-run

Desktop Name Resolution

The CLI intelligently resolves desktop names using:

1. Exact match (case-insensitive)
2. Fuzzy matching for typos and partial names
3. Substring matching as fallback

SSH Configuration

The SSH command automatically:

• Resolves SSH private keys (--identity, ~/.ssh/id_ed25519, ~/.ssh/id_rsa)
• Generates new ed25519 keys if none found
• Registers public keys with IsardVDI bastion
• Handles bastion connection on port 443

Authentication Flow

1. SAML 2.0 Authentication: Secure login via Azure Entra ID
2. Session Caching: Persistent sessions stored securely in ~/.config/isard/
3. Automatic Refresh: JWT tokens refreshed automatically on expiration
4. Force Refresh: Use --force flag to bypass cached sessions

Library Usage

Isard can also be used as a Python library:

from isard import login_to_gencat, get_desktops, start_desktop, delete_desktop, get_templates, create_desktop, get_spice_file

# Authenticate
session = login_to_gencat("[e-mail]", "password")

# Get desktops
desktops = get_desktops(session)

# Get available templates
templates = get_templates(session)

# Create a new desktop
desktop = create_desktop(session, template_id, "My Desktop", description="Test desktop")

# Start a desktop
start_desktop(session, desktop_id)

# Get SPICE file for remote viewing
spice_content = get_spice_file(session, desktop_id)

# Delete a desktop (move to trash)
delete_desktop(session, desktop_id)

# Permanently delete a desktop
from isard import delete_desktop_permanent
delete_desktop_permanent(session, desktop_id)

Configuration

Session Files

• ~/.config/isard/session.json - Gencat SAML session (user info, cookies)
• ~/.config/isard/isardvdi.json - IsardVDI JWT session (authentication token)

Both files are created with chmod 600 for security.

Environment Variables

• GENCAT_USERNAME - Your Gencat username
• GENCAT_PASSWORD - Your Gencat password

Requirements

• Python 3.14 or later
• Linux, macOS, or Windows
• Internet connection for authentication
• SSH client for desktop access
