[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 / Limitations
|
|
|
|
* Provides the same workflow as the Vagrant VirtualBox provider
|
|
* Port forwarding via [`redir`](http://linux.die.net/man/1/redir)
|
|
* Does not support public / private networks
|
|
* Assumes you have a `lxcbr0` bridge configured on your host similar to [Ubuntu's built-in](https://help.ubuntu.com/lts/serverguide/lxc.html#lxcbr0)
|
|
|
|
|
|
## Requirements
|
|
|
|
* [Vagrant 1.1+](http://downloads.vagrantup.com/)
|
|
* lxc 0.7.5+
|
|
* redir (if you are planning to use port forwarding)
|
|
* A [bug-free](https://github.com/fgrehm/vagrant-lxc/wiki/Troubleshooting#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 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).
|
|
|
|
Some manual steps are required to set up a Linode machine prior to using this
|
|
plugin, please check [the wiki](https://github.com/fgrehm/vagrant-lxc/wiki/Usage-on-Linode)
|
|
for more information. Documentation on how to set things up for other distros
|
|
[are welcome](https://github.com/fgrehm/vagrant-lxc/wiki) :)
|
|
|
|
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)**
|
|
|

|
|
## Installation
|
|
|
|
```
|
|
vagrant plugin install vagrant-lxc
|
|
```
|
|
|
|
|
|
## Usage
|
|
|
|
After installing, add a [base box](#base-boxes) 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:
|
|
|
|
```ruby
|
|
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 `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):
|
|
|
|
```ruby
|
|
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](http://manpages.ubuntu.com/manpages/quantal/man5/lxc.conf.5.html).
|
|
|
|
### Avoiding `sudo` passwords
|
|
|
|
This plugin requires **a lot** of `sudo`ing since [user namespaces](https://wiki.ubuntu.com/UserNamespace)
|
|
are not supported on mainstream kernels. Have a look at the [Wiki](https://github.com/fgrehm/vagrant-lxc/wiki/Avoiding-'sudo'-passwords)
|
|
to find out how to work around that specially if you are running an OS with sudo
|
|
< 1.8.4 (like Ubuntu 12.04) as you might be affected by a bug.
|
|
|
|
### Base boxes
|
|
|
|
Please check [the wiki](https://github.com/fgrehm/vagrant-lxc/wiki/Base-boxes)
|
|
for a list of [pre built](https://github.com/fgrehm/vagrant-lxc/wiki/Base-boxes#available-boxes)
|
|
base boxes and have a look at [`BOXES.md`](https://github.com/fgrehm/vagrant-lxc/tree/master/BOXES.md)
|
|
for more information on building your own.
