LXD is a system container manager

With LXD you can run hundreds of containers of a variety of Linux distributions, apply resource limits, pass in directories, USB devices or GPUs and setup any network and storage you want.

LXD containers are lightweight, secure by default and a great alternative to running Linux virtual machines.

Run any Linux distribution you want

Pre-made images are available for Ubuntu, Alpine Linux, ArchLinux, CentOS, Debian, Fedora, Gentoo, OpenSUSE and more.

A full list of available images can be found here: https://images.linuxcontainers.org

Can't find the distribution you want? It's easy to make your own images too, either using our distrobuilder tool or by assembling your own image tarball by hand.

Containers at scale

LXD is network aware and all interactions go through a simple REST API, making it possible to remotely interact with containers on remote systems, copying and moving them as you wish.

Want to go big? LXD also has built-in clustering support, letting you turn dozens of servers into one big LXD server.
