LXC – userspace interface for the Linux kernel containment features

LXC is a userspace interface for the Linux kernel containment features. Through a powerful API and simple tools, it lets Linux users easily create and manage system or application containers.

LXC containers are often considered as something in the middle between a chroot and a full fledged virtual machine. The goal of LXC is to create an environment as close as possible to a standard Linux installation but without the need for a separate kernel.

LXC is free and open source software.

Features include:

  • Kernel namespaces (ipc, uts, mount, pid, network and user).
  • Apparmor and SELinux profiles.
  • Seccomp policies.
  • Chroots (using pivot_root).
  • Kernel capabilities.
  • CGroups (control groups).

LXC is currently made of a few separate components:

  • The liblxc library.
  • Several language bindings for the API:
    • python3 (in-tree, long term support in 2.0.x).
    • lua (in tree, long term support in 2.0.x).
    • Go.
    • ruby.
    • python2.
    • Haskell.
  • A set of standard tools to control the containers.
  • Distribution container templates.
