This is a Vagrant plugin that allows it to control and provision Linux Containers as an alternative to the built in VirtualBox provider for Linux hosts. Check out this blog post to see it in action.
Features / Limitations
- Provides the same workflow as the Vagrant VirtualBox provider
- Port forwarding via
- Does not support public / private networks
- Assumes you have a
lxcbr0bridge configured on your host similar to Ubuntu's built-in
The plugin is known to work better and pretty much out of the box on Ubuntu 12.04+
hosts and installing the dependencies on it basically means a
apt-get install lxc lxc-templates cgroup-lite redir
apt-get update && apt-get dist-upgrade to upgrade the kernel. For Debian
hosts you'll need to follow the instructions described on the Wiki.
Some manual steps are required to set up a Linode machine prior to using this plugin, please check the wiki for more information. Documentation on how to set things up for other distros are welcome :)
If you are on a Mac or Windows machine, you might want to have a look at this blog post for some ideas on how to set things up or check out this other repo for a set of Vagrant VirtualBox machines ready for vagrant-lxc usage.
NOTE: Some users have been experiencing networking issues and right now you might need to disable checksum offloading as described on this comment
vagrant plugin install vagrant-lxc
After installing, add a base box using any name you want, for example:
vagrant box add quantal64 http://bit.ly/vagrant-lxc-quantal64-2013-10-23
Then create a Vagrantfile that looks like the following, changing the box name to the one you've just added:
Vagrant.configure("2") do |config| config.vm.box = "quantal64" end
And finally run
vagrant up --provider=lxc.
If you are using Vagrant 1.2+ you can also set
environmental variable to
lxc in order to avoid typing
If you want, you can modify container configurations from within your Vagrantfile using the provider block:
Vagrant.configure("2") do |config| config.vm.box = "quantal64" config.vm.provider :lxc do |lxc| # Same effect as 'customize ["modifyvm", :id, "--memory", "1024"]' for VirtualBox lxc.customize 'cgroup.memory.limit_in_bytes', '1024M' end end
vagrant-lxc will then write out
lxc.cgroup.memory.limit_in_bytes='1024M' to the
container config file (usually kept under
prior to starting it.
For other configuration options, please check the lxc.conf manpages.
By default vagrant-lxc will attempt to generate a unique container name
for you. However, if the container name is important to you, you may use the
container_name attribute to set it explicitly from the
Vagrant.configure("2") do |config| config.vm.box = "quantal64" config.vm.define "db" do |node| node.vm.provider :lxc do |lxc| lxc.container_name = :machine # Sets the container name to 'db' lxc.container_name = 'mysql' # Sets the container name to 'mysql' end end end
This plugin requires a lot of
sudoing since user namespaces
are not supported on mainstream kernels. Have a look at the Wiki
to find out how to work around that specially if you are running an OS with
< 1.8.4 (like Ubuntu 12.04) as you might be affected by a bug.
Please refer the wiki.
