•
Virtualbox
•
VMWare (kostenpflichtig)

$ vagrant init
$ vagrant up

12. Beispiel-Config mit puppet
Vagrant.configure("2") do |config|
!
config.vm.box = "debian-607"
config.vm.box_url = "http://puppet-vagrant-boxes.puppetlabs.com/debian-607-x64-vbox4210.box"
config.vm.provider "virtualbox" do |v|
v.customize ["modifyvm", :id, "--memory", "4096"]
v.customize ["modifyvm", :id, "--cpus", "4"]
end
config.vm.network :public_network
config.vm.network :forwarded_port, guest: 80, host: 8080
!
config.vm.hostname = „demo.hostname.local“
config.vm.provision :puppet_server do |puppet|
puppet.puppet_server = „puppet.meinhost.de“
