LXD leverages the Linux Container (LXC) system to create light, effective system containers. However, before we begin to use LXC/LXD, we need to ensure we have it properly installed, initialized, and otherwise configured. In this lab, we will install LXD 3.0 Stable on Ubuntu 18.04 and ensure it’s up and running.
Learning Objectives
Successfully complete this lab by achieving the following learning objectives:
- Install LXD
Install LXD via
snap:sudo snap install lxd --channel=3.0/stable- Add cloud_user to lxd Group
Ensure the
cloud_usercan executelxc/lxdcommands by adding it to thelxdgroup:sudo usermod cloud_user -aG lxdLog out then log back in.
- Initialize LXD
Initialize LXD and answer the prompts presented:
