Overview

Komandan is a server automation tool designed for simplicity and ease of use. It leverages the Lua programming language to provide a flexible and powerful interface for managing remote servers. Inspired by Ansible, Komandan operates over SSH, eliminating the need for agents on managed servers.

Key Features

  • Agentless Operation: Connects to target servers via SSH, requiring no additional software installation on the managed nodes.
  • Lua-Based Scripting: Utilizes Lua for scripting, offering a lightweight yet powerful language for automation tasks.
  • Modular Design: Provides built-in modules for common tasks such as executing commands (cmd), running scripts (script), uploading files (upload), and downloading files (download).
  • Built-in Functions: Offers helper functions like komandan.filter_hosts for filtering hosts based on names or tags and komandan.set_defaults for setting default values for connection parameters.
  • Ansible-Inspired Approach: Follows Ansible’s philosophy of simplicity and agentless operation, making it easy to learn and use.

How Komandan Works

Komandan executes Lua scripts that define tasks to be performed on remote servers. The komando function is the core of Komandan, responsible for establishing SSH connections and executing modules on target hosts.

Typical Workflow

  1. Define Hosts: Specify the target servers’ details, including address, port, username, and private key path.
  2. Create Tasks: Define tasks using Komandan’s built-in modules, such as executing commands or transferring files.
  3. Run Scripts: Execute the Lua script using the komandan command, which processes the tasks and performs the specified actions on the target hosts.

Benefits of Using Komandan

  • Simplified Server Management: Automates repetitive tasks, making server management more efficient.
  • Easy to Learn: Leverages the simple and intuitive Lua scripting language.
  • Flexible and Extensible: Allows for the creation of custom scripts and modules to meet specific needs.
  • Agentless Architecture: Reduces the complexity of managing remote servers by eliminating the need for agent software.

Komandan is a powerful tool for automating server management tasks. Its simple design, combined with the flexibility of Lua scripting, makes it an excellent choice for both novice and experienced users.
