These slides show how to use Vagrant with OpenStack and gives some examples. I held this talk at the OpenStack Meetup in Nuremberg in January 2015.

OpenStack and Vagrant
How to explore the greatness of OpenStack with Vagrant
Yves Fauser
Solutions Architect @ VMware

2. What is Vagrant – The Goals of Vagrant
Quote from Vagrant Web-Site:
“Create and configure
lightweight,
reproducible,
and portable
development environments.”

3. What is Vagrant
Repeatable
Quickly Build and destroy single machine and multi-machine environments
Configurable
Describe all the steps to build an environment in a single file, and bundle all the additional
needed resources in a folder structure on your local machine
Easy to use, easy to share
Share environments through version control like Git or with tar files (box files in Vagrant)
and then simply type “vagrant up” to start
Extensible
Large community of people contribute extensions (plugins and providers) to Vagrant –
Like the OpenStack Plugin, VMware plugin, etc. …. It’s all Ruby

4. What is Vagrant – How this relates to config management
Configuration Management
Vagrant starts the VM, orchestrates the access to the VM
(using keypair based authentication).
It also does some customization of the VM based on its OS Knowledge
(e.g. setting the Hostname and shares files between the developers machine
and the VM)
After this Vagrant “hands off” the task of configuring the VM to some form of
configuration management tool like:
Shell scripts
Puppet
Chef
Ansible

5. What is Vagrant – The Vagrantfile
Vagrant.configure(2) do |config|!
config.vm.box = "hashicorp/precise64"!
config.vm.network "forwarded_port", guest: 80, host: 3080!
!
config.vm.synced_folder "www", "/var/www"!
!
config.vm.provision 'shell', inline: !
'apt-get update && apt-get install apache2 -y'!
!
end!
Again, …. It’s all Ruby
ON TO A DEMO

6. What is Vagrant – Vagrant Providers
Vagrant Providers
Vagrant is hypervisor agnostic through so called “provider”
Vagrant provides a virtualbox provider by default
Hashicorp offers a commercial VMware Provider (Fusion / Workstation)
with a support model
Everybody can write a provider and offer it as a rubygem
(rubygems.org => Just search for Vagrant)
Example community driven providers are:
OpenStack, AWS, vSphere (ESX and vCenter), vCloud Director / vCloudAir, KVM, Parallels,
open VMware fusion / workstation, etc.

7. What is Vagrant – Vagrant Providers
Vagrant Providers
Vagrant offers a CLI to easily install Vagrant providers / plugins
from rubygems.org
yfauser$ vagrant plugin list!
vagrant-openstack-plugin (0.11.1)!
vagrant-share (1.1.4, system)!
vagrant-vcenter (0.3.2)!
vagrant-vmware-fusion (3.1.2)!
!
yfauser$ vagrant plugin help!
Usage: vagrant plugin <command> [<args>]!
!
Available subcommands:!
install!
license!
list!
uninstall!
update!

8. Vagrant OpenStack Providers
There is a big number of vagrant OpenStack providers available
The first one was the Rackspace provider:
https://rubygems.org/gems/rackspace
First non cloud provider specific fork from Edmund Haselwanter:
https://rubygems.org/gems/vagrant-openstack-plugin
New provider with added feature from Guillaume Giamarchi (also, it doesn’t
use fog):
https://rubygems.org/gems/vagrant-openstack-provider
And many more ….

9. Vagrant OpenStack Provider - Vagrantfile
require 'vagrant-openstack-plugin'!
!
Vagrant.configure("2") do |config|!
config.vm.box = "dummy"!
config.vm.hostname = "RubyWebDev”!
# Make sure the private key from the key pair is provided!
config.ssh.private_key_path = "~/.ssh/MyOpenStackSecretKey.pem”!
!
config.vm.provider :openstack do |os|!
os.username = "#{ENV['OS_USERNAME']}" # e.g. "#{ENV['OS_USERNAME']}"!
os.api_key = "#{ENV['OS_PASSWORD']}" # e.g. "#{ENV['OS_PASSWORD']}"!
os.flavor = /m1.small/ ! # Regex or String!
os.image = /Ubuntu 14.04 Cloud-Init with Puppet/ # Regex or String!
os.endpoint = "#{ENV['OS_AUTH_URL']}/tokens" # e.g. "#{ENV['OS_AUTH_URL']}/tokens"!
os.keypair_name = ”MyOpenStackKeypair" # as stored in Nova!
os.ssh_username = "ubuntu" # login for the VM!
os.network = "LabNet" # optional!
os.security_groups = ['Allow-All'] # optional!
os.tenant = "#{ENV['OS_TENANT_NAME']}" # optional!
os.floating_ip = :auto # optional (The floating IP to assign for this instance … !
os.floating_ip_pool = ”Router-Uplink-Network" # optional (The floating IP pool to allocate addresses from!
end!
!
config.vm.synced_folder "rails", "/home/ubuntu/rails” !
!
config.vm.provision "puppet" do |puppet|!
puppet.manifest_file = "Web-Server.pp"!
puppet.options = "--verbose --debug"!
end!
!
end!

10. Vagrant OpenStack Provider - Caveats
File sharing uses rsync over ssh only, so there is no instant update of the files
you share
However Vagrant can automatically watch and update your files with the
“rsync-auto” command
You need to install the “dummy box” with:
vagrant box add dummy
https://github.com/cloudbau/vagrant-openstack-plugin/raw/master/dummy.box
Be careful not to place sensitive data like the OS_PASSWORD into the
Vagrantfile, it will by default be copied into the VM in the /vagrant path
