I do not use vagrant anymore, and thus this is unmaintained since quite a long time. If you care about this feature, please talk to me if you would like to maintain it.
vagrant-hosts
is a plugin for Vagrant which allows a developer to automatically add or remove local hosts entries when bringing up or shutting down machines with vagrant.
NOTE: This plugin requires Vagrant 0.8 or later.
To use this plugin, first install Vagrant 0.8 or later and ensure that you have augeas installed. Next, install this gem:
gem install vagrant-hosts
To configure it put something along these lines into your Vagrantfile:
Vagrant::Config.run do |config|
config.hosts.names = ["host.name", "another.name"]
end
