The regex check for the container MAC address presence in the dnsmasq leases file is case sensitive. Dnsmasq outputs uppercase addresses in the leases file. As MAC addresses are generally considered case insensitive, it makes sense to relax the regular expression check to allow for this. |

vagrant-lxc
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.
NOTICE: The master branch is targetting an initial beta for 1.0.0, for the latest stable version of the plugin, please check the 0.8-stable branch.
Features
- Provides the same workflow as the Vagrant VirtualBox provider
- Port forwarding via
redir
As of now, it does not support public / private networks, but private networks will be coming along soon.
Requirements
- Vagrant 1.1+
- lxc 0.7.5+
redir(if you are planning to use port forwarding)- A kernel != 3.5.0-17.28
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
and a 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
Installation
On Vagrant 1.5+:
vagrant plugin install vagrant-lxc --plugin-version 1.0.0.alpha.1
On Vagrant < 1.5:
vagrant plugin install vagrant-lxc
Quick start
On Vagrant 1.5+:
vagrant init fgrehm/precise64-lxc
vagrant up --provider=lxc
On Vagrant < 1.5:
vagrant init precise64 http://bit.ly/vagrant-lxc-precise64-2013-10-23
vagrant up --provider=lxc
If you are using Vagrant 1.2+ you can also set the VAGRANT_DEFAULT_PROVIDER
environmental variable to lxc in order to avoid typing --provider=lxc all
the time.
Advanced configuration
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 /var/lib/lxc/<container>/config)
prior to starting it.
For other configuration options, please check the lxc.conf manpages.
Container naming
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 provider block:
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
Avoiding sudo passwords
This plugin requires a lot of sudoing since user namespaces
are not supported on mainstream kernels. To work around that, you can use the
vagrant lxc sudoers command which will create a file under /etc/sudoers.d/vagrant-lxc-<VERSION>
whitelisting all commands required by vagrant-lxc to run.
If you are interested on what will be generated by that command, please check this code.
