System.LXC

Description

Create, control and manage LXC containers through Haskell API. You can get more info about LXC at https://help.ubuntu.com/lts/serverguide/lxc.html and https://linuxcontainers.org.

Most of container-related functions (e.g. start, attach, destroy) perform in 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
