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 the plugin in action and find out more about it.
Features / Limitations
- Provides the same workflow as the Vagrant VirtualBox provider
- Port forwarding via
redir
- Does not support private networks
Please refer to the closed issues and the changelog for most up to date information.
Requirements
- Vagrant 1.1+
- lxc 0.7.5+
- redir (if you are planning to use port forwarding)
- A bug-free 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.
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. 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: http://the.taoofmac.com/space/HOWTO/Vagrant or use use the same Ubuntu 12.10 VirtualBox machine I use for development.
Installation
vagrant plugin install vagrant-lxc
Usage
After installing, add a base box using any name you want, for example:
vagrant box add quantal64 http://bit.ly/vagrant-lxc-quantal64-2013-07-12
Then create a Vagrantfile that looks like the following, changing the box name to the one you've just added:
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:
Vagrant.configure("2") do |config|
config.vm.box = "quantal64"
config.vm.provider :lxc do |lxc|
# Same effect as 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-name>/config
)
prior to starting it.
For other configuration options, please check the lxc.conf manpages.
Avoiding sudo
passwords
This plugin requires a lot of sudo
ing since user namespaces
are not supported on mainstream kernels. Have a look at the Wiki
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
for a list of pre built
base boxes and have a look at BOXES.md
for more information on building your own.
