Auto-Boot Ollama Host

This directory contains the auto-boot-ollama-host script, organized into multiple modules for better maintainability and structure.

File Structure

Main Script

• auto-boot-ollama-host.lua - Main script that orchestrates all functionality

Modules

config.lua

Handles all environment variable configuration with sensible defaults:

• Docker configuration (container name, since time)
• Ollama service configuration (host, port)
• SSH configuration (port, user, identity file)
• Pattern configuration (error and finish patterns)
• Wake-on-LAN configuration

utils.lua

Provides utility functions:

• log(msg) - Timestamped logging
• getenv(name, def) - Environment variable with default

network.lua

Network-related functionality:

• port_is_up(host, port, timeout) - Check if TCP port is accessible
• send_wol(mac, bcast_ip, port) - Send Wake-on-LAN magic packet

ssh.lua

SSH command execution:

• execute(command, user, host, port, identity_file) - Execute remote SSH command
• execute_with_output(command, user, host, port, identity_file) - Execute SSH command and return output

ollama_manager.lua

Ollama service management:

• start_service(config) - Start Ollama service via SSH
• stop_service_and_shutdown(config) - Stop service and shutdown host

session_check.lua

Windows desktop session detection:

• is_user_logged_in_enhanced(config) - Check if user is logged into desktop session

Benefits of Modular Structure

1. Separation of Concerns: Each module has a single responsibility
2. Reusability: Modules can be reused in other projects
3. Testability: Individual modules can be unit tested
4. Maintainability: Easier to locate and modify specific functionality
5. Readability: Clear structure and organization
6. Configuration: Centralized configuration management

New Features

Desktop Session Detection

The script includes Windows desktop session detection:

• Checks if the SSH_USER is currently logged into a Windows desktop session
• If user is logged in, skips Ollama startup/shutdown to avoid interruption
• If user is not logged in, proceeds with normal operation

Usage

To use the script, simply run:

lua auto-boot-ollama-host.lua

The script provides a modular structure for better maintainability while maintaining all functionality.
