[LXC](http://lxc.sourceforge.net/) provider for [Vagrant](http://www.vagrantup.com/) 1.1+
2013-03-03 03:38:48 +00:00
This is a Vagrant plugin that allows it to control and provision Linux Containers
as an alternative to the built in Vagrant VirtualBox provider for Linux hosts.

Check out this [blog post](http://fabiorehm.com/blog/2013/04/28/lxc-provider-for-vagrant)
to see the plugin in action and find out more about it.

## Features
2013-03-03 03:38:48 +00:00
* Vagrant's `up`, `halt`, `reload`, `destroy`, `ssh`, `provision` and `package` commands
2013-05-17 23:22:30 +00:00
* Shared folders
* Provisioning with any built-in Vagrant provisioner
* Port forwarding
* Setting container's host name
2013-05-17 23:22:30 +00:00
*Please refer to the [closed issues](https://github.com/fgrehm/vagrant-lxc/issues?labels=&milestone=&page=1&state=closed)
and the [changelog](CHANGELOG.md) for most up to date information.*

## Requirements
* [Vagrant 1.1+](http://downloads.vagrantup.com/)
* lxc 0.7.5+
* redir (if you are planning to use port forwarding)
* A [bug-free](#help-im-unable-to-restart-containers) kernel
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 redir`
and a `apt-get update && apt-get dist-upgrade` to upgrade the kernel.
Some manual steps are required to set up a Linode machine prior to using this
plugin, please check https://github.com/fgrehm/vagrant-lxc/wiki/Usage-on-Linode
for more information. The same applies to Debian hosts and documentation will be
provided soon.
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: http://the.taoofmac.com/space/HOWTO/Vagrant
or use use the same [Ubuntu 12.10 VirtualBox machine I use for development](https://github.com/fgrehm/vagrant-lxc/wiki/Development#using-virtualbox-for-development).

## Installation
```
vagrant plugin install vagrant-lxc
```
2013-03-03 03:38:48 +00:00
## Usage
2013-07-08 01:17:54 +00:00
After installing, add a [base box](#base-boxes) using any name you want, for example:
2013-03-03 03:38:48 +00:00
```
2013-05-09 00:12:13 +00:00
vagrant box add quantal64 http://dl.dropbox.com/u/13510779/lxc-quantal-amd64-2013-05-08.box
2013-03-03 03:38:48 +00:00
```
2013-05-17 23:22:30 +00:00
Then create a Vagrantfile that looks like the following, changing the box name
to the one you've just added:
2013-03-03 03:38:48 +00:00
```ruby
Vagrant.configure("2") do |config|
2013-05-17 23:22:30 +00:00
config.vm.box = "quantal64"
end
```
And finally run `vagrant up --provider=lxc`.
If you are using Vagrant 1.2+ you can also set `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](http://docs.vagrantup.com/v2/providers/configuration.html):
2013-03-04 01:42:18 +00:00
2013-05-17 23:22:30 +00:00
```ruby
Vagrant.configure("2") do |config|
config.vm.box = "quantal64"
2013-03-03 03:38:48 +00:00
config.vm.provider :lxc do |lxc|
2013-05-17 23:22:30 +00:00
# Same effect as as 'customize ["modifyvm", :id, "--memory", "1024"]' for VirtualBox
2013-04-10 06:12:10 +00:00
lxc.customize 'cgroup.memory.limit_in_bytes', '1024M'
2013-03-03 03:38:48 +00:00
end
end
```
2013-05-17 23:22:30 +00:00
This will make vagrant-lxc pass in `-s lxc.cgroup.memory.limit_in_bytes=1024M`
to `lxc-start` when booting containers. This will override any previously value
set from container's configuration file that is usually kept under
`/var/lib/lxc/<container-name>/config`.
For other configuration options, please check [lxc.conf manpages](http://manpages.ubuntu.com/manpages/quantal/man5/lxc.conf.5.html).

## Current limitations
2013-05-17 23:22:30 +00:00
* The plugin does not detect forwarded ports collision, right now you are
responsible for taking care of that.
* There is a hell lot of `sudo`s involved and this will probably be around until
2013-06-06 17:19:46 +00:00
[user namespaces](https://wiki.ubuntu.com/LxcSecurity) are supported or I'm able to handle [#90](https://github.com/fgrehm/vagrant-lxc/issues/90)
* [Does not tell you if dependencies are not met](https://github.com/fgrehm/vagrant-lxc/issues/11)
(will probably just throw up some random error)
* + bunch of other [core features](https://github.com/fgrehm/vagrant-lxc/issues?labels=core&milestone=&page=1&state=open)
and some known [bugs](https://github.com/fgrehm/vagrant-lxc/issues?labels=bug&page=1&state=open)
