Setting Up Linux Containers (LXD) on QNAP Devices

Summary

Introduction to LXD on QNAP

QNAP NAS devices can be transformed into powerful home servers using LXD container technology. This guide will help you set up and manage Linux containers on your QNAP system.

Key Benefits
  • Deploy lightweight and secure Linux containers
  • Support for Ubuntu and Debian distributions
  • Ideal for hosting media servers, development environments, and more

Prerequisites

  • QNAP model with Container Station support
  • QNAP account with administrative access
  • Basic understanding of Linux and container concepts

Installing Container Station

  1. Log into your QNAP device's web interface
  2. Navigate to the App Center
  3. Search for "Container Station" and install it
  4. Open Container Station and enable both LXC and Docker

Setting Up LXD
