Hackage package Build Status

High level Haskell bindings to LXC (Linux containers).

The library provides Haskell LXC API, wrapping bindings-lxc package.

Requirements

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

Although there is lxc-dev package in standard Ubuntu repositories, 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

Most of container-related functions (e.g. start, attach, destroy) perform in a LXC monad. To run LXC a computation you need to specify a container using withContainer function. When working with a single container it might be handy to have an alias like this:

let containerName = withContainer (Container "container-name" configPath)

You can start using Haskell LXC API bindings similar to a command line tool from GHCi:

$ ghci
>>> import System.LXC
>>> let trusty = withContainer (Container "trusty" Nothing)
>>> trusty $ create "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
>>> trusty $ start False []
True
>>> trusty state
ContainerRunning
>>> trusty $ attachRunWait defaultAttachOptions "echo" ["echo", "Hello, world!"]
Hello, world!
Just ExitSuccess
>>> trusty stop
True
>>> Just trustySnapC <- trusty $ clone (Just "trusty-snap") Nothing [CloneSnapshot] Nothing Nothing Nothing []
>>> let trustySnap = withContainer trustySnapC
>>> trustySnap $ start False []
True
>>> trustySnap getInterfaces
["eth0","lo"]
>>> trustySnap $ getIPs "eth0" "inet" 0
["10.0.3.135"]
>>> trustySnap $ shutdown (-1)
True
>>> trustySnap state
ContainerStopped
