# vagrant-lxc base boxes
|
|
|
|
Although the official documentation says it is only supported for VirtualBox
|
|
environments, you can use the [`vagrant package`](http://docs.vagrantup.com/v2/cli/package.html)
|
|
command to export a `.box` file from an existing vagrant-lxc container.
|
|
|
|
There is also a set of [bash scripts](https://github.com/fgrehm/vagrant-lxc/tree/master/boxes)
|
|
that you can use to build base boxes as needed. By default it won't include any
|
|
provisioning tool and you can pick the ones you want by providing some environment
|
|
variables.
|
|
|
|
For example:
|
|
|
|
```
|
|
git clone https://github.com/fgrehm/vagrant-lxc.git
|
|
cd vagrant-lxc/boxes
|
|
PUPPET=1 CHEF=1 sudo -E ./build-ubuntu-box.sh precise amd64
|
|
```
|
|
|
|
Will build a Ubuntu Precise x86_64 box with latest Puppet and Chef pre-installed, please refer to the scripts for more information.
