Ruby-LXC

Introduction

Ruby-LXC is a Ruby binding for liblxc. It allows the creation and management of Linux Containers from Ruby scripts.

Build and installation

Currently the binding is developed and tested against liblxc 1.0.0 build. To build ruby-lxc you need

  • ubuntu 14.04
  • lxc ipackage
sudo apt-get install lxc liblxc0 lxc-dev
  • Build essential for compiling the bindings
sudo apt-get install build-essential
  • Clone this repository and run the commands below (assuming you have bundler).
bundle install
bundle exec rake compile
gem install pkg/ruby-lxc-0.1.0.gem

or just add this to your Gemfile

gem "ruby-lxc", github: "andrenth/ruby-lxc"

Usage

  • Container lifecycle management (create, start, stop and destroy containers)
c = LXC::Container.new('foo')
c.create('ubuntu') # create a container named foo with ubuntu template
c.start
c.stop
c.destroy
  • Additional state changing operations (freezing, unfreezing and cloning containers)
c.freeze
c.unfreeze
c.reboot
c.shutdown
  • Clone a container
c.clone('bar') # clone foo into bar. parent container has to bee in freeze or stopped state.
  • Wait for a state change
c.wait('STOPPED', 10) # wait till container goes to STOPPED state, else timeout after 10 seconds
