This page contains a list of handy LXD commands for beginners to get started with LXD. Every command in this guide has been tested on an Ubuntu 16.04 machine.

- Setting up NAT for the network bridge (or not)
Checking LXD version

Getting a list of available images from an image server
sudo lxc image list images:

Creating a new container
sudo lxc init images:ubuntu/yakkety/amd64 ubuntu-test-1

Stopping a container

Removing a container

You can force this command with --force if needed.

Executing a command on a container
sudo lxc exec ubuntu-test-1 ping 188.8.131.52
