Getting Vagrant Started

Here’s a short overview of the commands involved in getting Vagrant going.

$ mkdir vagrant-test
$ vagrant init
$ vagrant box add precise64 files.vagrantup.com/precise64.box

Getting Puppet Started

Now create the directories and config files required for Puppet.

$ mkdir puppet; mkdir puppet/manifests; mkdir puppet/modules
$ touch puppet/manifests/appserver.pp; touch puppet/manifests/rvm.pp; touch puppet/manifests/users.pp

Directory structure:

├── Vagrantfile
└── puppet
├── manifests
│├── appserver.pp
│├── rvm.pp
│├── users.pp
└── modules

Configuring Vagrant

Vagrantfile

config.vm.box = “precise64”
config.vm.box_url = “http://files.vagrantup.com/precise64.box”
# make sure our apt sources are up to date…
config.vm.provision :shell, :inline => “apt-get update –fix-missing”# config for the appserver box, same name as .pp file.
config.vm.define “appserver” do |app|
# do not show a VirtualBox window
app.vm.boot_mode = :headless
#app.vm.network :hostonly, “66.66.66.10”
# bridge the VM on the host’s eth0 interface
# if eth0 does not exist then Vagrant will
# prompt you to select an actual interface.
app.vm.network :bridged, :bridge => “eth0”
#Puppet gets grumpy if the hostname is not a FQDN…
app.vm.host_name = “appserver00.local”app.vm.provision :puppet do |puppet|# change fqdn to give to change the vm virtual host
puppet.facter = {

The magical one-liner

$ vagrant up

A simple list of vagrant commands

vagrant up boxname start the given box. If the box has not been initialized and created, this will download the basebox as required, bootstrap it and run the provisioner. Running vagrant up when the box is already running is a NOOP and has no effect.

vagrant halt boxname stop the given box. Has no effect if the box is not running. May require an invocation using the –force flag (vagrant halt –force ) if the box crashed, locked up or cannot be accessed via vagrant ssh
vagrant reload boxname stop and start the given box. Runs the provisioner.

vagrant provision boxname Runs the provisioner.

vagrant destroy boxname destroys the given box. This is useful if for some reason the box has been damaged or to free diskspace. Running vagrant up after running vagrant destroy bootstraps a new box.

vagrant ssh boxname open an ssh connection to the given box.
