Ruby-LXC is a Ruby binding for liblxc. It allows the creation and management of Linux Containers from Ruby scripts.
Build and installation
Assuming a current installation of LXC is available, to install Ruby-LXC simply run the commands below
sudo apt-get install ruby-dev lxc-dev bundle install bundle exec rake compile bundle exec rake gem gem install pkg/ruby-lxc-1.2.0.gem
or just add this to your
gem "ruby-lxc", github: "lxc/ruby-lxc", require: "lxc"
Container lifecycle management (create, start, stop and destroy containers)
require 'lxc' c = LXC::Container.new('foo') c.create('ubuntu') # create a container named foo with ubuntu template c.start # attach to a running container c.attach do LXC.run_command('ifconfig eth0') end c.stop c.destroy
c.name c.config_path c.config_item('lxc.cap.drop') c.cgroup_item('memory.limit_in_bytes') c.init_pid c.interfaces c.ip_addresses c.state
Additional state changing operations (freezing, unfreezing and cloning containers)
c.freeze c.unfreeze c.reboot c.shutdown
Clone a container
# clone foo into bar. Parent container has to be frozen or stopped. clone = c.clone('bar')
Wait for a state change
# wait until container goes to STOPPED state, else timeout after 10 seconds c.wait(:stopped, 10)
