Description

This repository contains various bash scripts created with the intention of making lxd container creation and maintenance quicker and easier.

Prerequisites

In order to guarantee a flawless execution, there are certain criteria that should be met.

• The host device is running Ubuntu 18.04 LTS
• The storage backend is either zfs or btrfs
• Quotas are enabled for the storage backend of choice

This is not to say you will not be able to run the scripts using any other setup, but this is the environment in which they have been tested and confirmed to work without major issues.

Installation

Download the and run the installation script.

wget https://raw.githubusercontent.com/hoernsten/lxd/master/install.sh
chmod +x install.sh
sudo ./install.sh

It will then be installed to /opt/lxd, and a symbolic link will be created in /usr/local/bin.

Remember to make sure the current user is a member of the lxd group.

groups $USER | grep -o lxd
