Plugins

Vagrant provides a fully supported plugin interface in order to allow users to modify or extend the features of Vagrant. Plugins are powerful, first-class citizens and even much of the core of Vagrant is built using plugins. What can plugins do?

Add new commands to the vagrant command, such as vagrant my-great-plugin
Modify the functionality of existing commands, such as adding new behavior when vagrant up is called.
Add new configuration classes so that your plugin can be configured using a Vagrantfile, for example with config.my_plugin.
Add new provisioners, such as Chef or Puppet.
Add new guest or host classes, so that Vagrant can work on new systems that the released version may not support yet.
