[LXC](http://lxc.sourceforge.net/) provider for [Vagrant](http://www.vagrantup.com/) 1.9+
[LXC](http://lxc.sourceforge.net/) provider for [Vagrant](http://www.vagrantup.com/) 1.1+
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](http://fabiorehm.com/blog/2013/04/28/lxc-provider-for-vagrant/)
to see it in action.
## Features
* Provides the same workflow as the Vagrant VirtualBox provider
* Port forwarding via [`redir`](https://github.com/troglobit/redir)
* Private networking via [`pipework`](https://github.com/jpetazzo/pipework)
* Port forwarding via [`redir`](http://linux.die.net/man/1/redir)
## Requirements
* [Vagrant 1.9+](http://www.vagrantup.com/downloads.html)
* lxc >=2.1
* [Vagrant 1.1+](http://www.vagrantup.com/downloads.html)
* lxc 0.7.5+
* `redir` (if you are planning to use port forwarding)
* `brctl` (if you are planning to use private networks, on Ubuntu this means `apt-get install bridge-utils`)
* A [kernel != 3.5.0-17.28](https://github.com/fgrehm/vagrant-lxc/wiki/Troubleshooting#wiki-im-unable-to-restart-containers)
The plugin is known to work better and pretty much out of the box on Ubuntu 14.04+
hosts and installing the dependencies on it basically means a
`apt-get install lxc lxc-templates cgroup-lite redir`. For setting up other
types of hosts please have a look at the [Wiki](https://github.com/fgrehm/vagrant-lxc/wiki).
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](https://github.com/fgrehm/vagrant-lxc/wiki/Usage-on-debian-hosts)
and old lxc versions (like 0.7.5 shipped with Ubuntu 12.04 by default) might require
[additional configurations to work](#backingstore-options).
If you are on a Mac or Windows machine, you might want to have a look at [this](http://the.taoofmac.com/space/HOWTO/Vagrant)
blog post for some ideas on how to set things up or check out [this other repo](https://github.com/fgrehm/vagrant-lxc-vbox-hosts)
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](https://github.com/fgrehm/vagrant-lxc/issues/153#issuecomment-26441273)**

For other configuration options, please check the [lxc.conf manpages](http://manpages.ubuntu.com/manpages/precise/man5/lxc.conf.5.html).
### Private Networks
Starting with vagrant-lxc 1.1.0, there is some rudimentary support for configuring
[Private Networks](https://docs.vagrantup.com/v2/networking/private_network.html)
by leveraging the [pipework](https://github.com/jpetazzo/pipework) project.
On its current state, there is a requirement for setting the bridge name that
will be created and will allow your machine to comunicate with the container
For example:
```ruby
Vagrant.configure("2") do |config|
config.vm.network "private_network", ip: "192.168.2.100", lxc__bridge_name: 'vlxcbr1'
end
```
Will create a new `veth` device for the container and will set up (or reuse)
a `vlxcbr1` bridge between your machine and the `veth` device. Once the last
vagrant-lxc container attached to the bridge gets `vagrant halt`ed, the plugin
will delete the bridge.
### Container naming
By default vagrant-lxc will attempt to generate a unique container name

_Please note that there is a 64 chars limit and the container name will be
trimmed down to that to ensure we can always bring the container up.

@ -142,33 +119,31 @@ Vagrant.configure("2") do |config|

## Unprivileged containers support
Since v1.4.0, `vagrant-lxc` gained support for unprivileged containers. For now, since it's a new
feature, privileged containers are still the default, but you can have your `Vagrantfile` use
unprivileged containers with the `privileged` flag (which defaults to `true`). Example:
For old versions of lxc (like 0.7.5 shipped with Ubuntu 12.04 by default) that
does not support `best` for the backingstore option, changing it to `none` is
required and a default for all Vagrant environments can be set from your
`~/.vagrant.d/Vagrantfile` using the same `provider` block:
```ruby
Vagrant.configure("2") do |config|
config.vm.provider :lxc do |lxc|
lxc.privileged = false
lxc.backingstore = 'none'
end
end
```
For unprivileged containers to work with `vagrant-lxc`, you need a properly configured system. On
some distros, it can be somewhat of a challenge. Your journey to configuring your system can start
with [Stéphane Graber's blog post about it](https://stgraber.org/2014/01/17/lxc-1-0-unprivileged-containers/).
### Avoiding `sudo` passwords
## Avoiding `sudo` passwords
If you're not using unprivileged containers, this plugin requires **a lot** of `sudo`ing To work
around that, you can use the `vagrant lxc sudoers` command which will create a file under
`/etc/sudoers.d/vagrant-lxc` whitelisting all commands required by `vagrant-lxc` to run.
This plugin requires **a lot** of `sudo`ing since [user namespaces](https://wiki.ubuntu.com/UserNamespace)
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](lib/vagrant-lxc/command/sudoers.rb).

A _"hypothetical"_ gem that helps Vagrant plugin developers to stay sane when
keeping up with Vagrant improvements by backporting parts of its recent versions
functionality.
More information will be provided if there is enough interest on having this
extracted as a separate gem.
