About this Hands-on Lab

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.

Learning Objectives

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

Following the list of items you have been provided in the Activity Guide, you will end up with a configured LXC/LXD system ready for images and containers. You start the configuration process with:

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:

lxc list

To see the current state (which should be empty of images)

Additional Resources

At the start of this Learning Activity, you will be provisioned a single Ubuntu 16.04 LTS image intended for use. Using the credentials and connectivity information at the start of this activity, once connected to the server, please open the Activity Guide for instructions on completing the activity.

PLEASE NOTE: When this server first becomes available, it will automatically run a 'apt-get update' which may take a few minutes to complete. Please wait before attempting to complete your tasks (you can check via 'ps aux | grep apt' to see if the update process is running).
