Sure, Stéphane Graber's (main LXD developer) excellent blog is really
the best place to start:
Once LXD is installed, it's quite simple to get started:
creates a basic general (YAML-encoded) framework by asking a bunch of
questions. Then let's say you need an Ubuntu 16.04 - based container:
lxc image copy ubuntu:16.04 local: --alias ubuntu16
will make a local copy of the container image. Note: you don't need to
keep a local copy, but I find it faster and easier when I'm testing and
creating/deleting containers frequently.
lxc launch ubuntu16 my_container -c security.privileged=true
creates and launches a container called "my_container" based on Ubuntu16.
You can ssh to this container:
lxc exec my_container -- bash
and now you're root on an Ubuntu16 machine and can do whatever you would
normally do on a linux host; e.g.
# apt install samba
You can pretty easily assign a static IP address, set up an included
proxy daemon that proxies certain ports to this container, delete,
The way to think of this kind of container is that it's an independent
linux machine running on an existing linux box. A couple of years ago
the conventional wisdom was LXD is great, but is hard to set up on
anything but Ubuntu; but this is no longer true; I only run it on Arch
linux host systems and have had virtually no issues (sure, since
Canonical bankrolls the development, it works best on Ubuntu).
It's also pretty efficient; Canonical container engineer Dustin Kirkland
wrote a blog post about running 500 LXD containers simultaneously on his
The hardest part for me was getting the networking right (bridge?
macvlan? etc..); otherwise it's basically just like working with an
ordinary linux machine.
