Containers are more and more important in any IT environment. Although the most commonly known container management system is Docker, there are other container engines available. In this activity, you will install and configure the Linux Containers (LXC) and learn how to run basic commands to be sure it is available for use.
Successfully complete this lab by achieving the following learning objectives:
- Install the Necessary Packages
Installing the packages is easy, in most cases on Ubuntu, they will already be installed, but should you need to a simple:
sudo apt install lxd lxd-client
Will take care of it!
- Configure the LXD System

sudo lxd init
- Allow the ‘cloud_user’ to Run LXC/LXD Commands
The ‘cloud_user’ user needs to be added to the ‘lxd’ group, via:
sudo usermod -aG lxd cloud_user
You can verify by logging out and back in as the cloud_user and running the command:
