lxc

High level Haskell bindings to LXC (Linux containers).

The library provides Haskell LXC API, wrapping <http://hackage.haskell.org/package/bindings-lxc bindings-lxc package>.

Requirements

Before installation make sure you have LXC installed on your system with header files and static library.

On Ubuntu 14.04 LTS (Trusty Tahr):

$ sudo apt-get install lxc-dev

On previous Ubuntu versions (including 12.04 LTS Precise Pangolin) standard repositories do not contain liblxc1 package. You might want to use ppa:ubuntu-lxc/stable repository instead:

$ sudo apt-get install software-properties-common python-software-properties
$ sudo add-apt-repository ppa:ubuntu-lxc/stable
$ sudo apt-get update
$ sudo apt-get install lxc-dev

Installation

Get the latest stable version from Hackage:

$ cabal install lxc

or clone this repository:

$ git clone https://github.com/fizruk/lxc.git
$ cd lxc
$ cabal install

Documentation

Haddock documentation is available at http://fizruk.github.io/lxc/docs/

Usage

You can start using these bindings just like command line tool:

>>> trusty <- mkContainer "trusty" Nothing
>>> create trusty "download" Nothing Nothing [] ["-d", "ubuntu", "-r", "trusty", "-a", "amd64"]
Using image from local cache
Unpacking the rootfs

---
You just created an Ubuntu container (release=trusty, arch=amd64, variant=default)
The default username/password is: ubuntu / ubuntu
To gain root privileges, please use sudo.

True
>>> start trusty False []
True
>>> state trusty
ContainerRunning
>>> attachRunWait trusty defaultAttachOptions "echo" ["echo", "Hello, world!"]
Hello, world!
Just ExitSuccess
>>> stop trusty
True
>>> trustySnap <- clone trusty (Just "trusty-snap") Nothing [CloneSnapshot] Nothing Nothing Nothing []
>>> start trustySnap False []
True
>>> getInterfaces trustySnap
["eth0","lo"]
>>> getIPs trustySnap "eth0" "inet" 0
["10.0.3.135"]
>>> shutdown trustySnap (-1)
True
>>> state trustySnap
ContainerStopped
