OPENHAB in a NUTSHELL: 63. CONSOLE - The OPENHAB Engine - Bundles and Features (Karaf) - VIDEO [Versione in italiano]

by Marco Lamanna

In this episode, we explore openHAB's 'Modulith' architecture.

We'll discover how Apache Karaf, the engine that runs the system, manages individual components called Bundles.

In this video, we'll delve into:

  • Bundle Anatomy: How to list all installed modules with bundle:list and how to identify the technical symbolic names needed for logging and configuration.
  • Surgical Control: We'll see how to resolve binding issues by restarting only the affected module with the stop and start commands without restarting the entire system.
  • The Secret of Features: We'll explain what features are and how to manage them; in particular, we'll understand why the bundle:uninstall command often doesn't work correctly. You'll discover the role of Features and how these software "recipes" keep your add-ons intact.
