This document discusses using Vagrant and Ansible for infrastructure automation. It introduces Vagrant as a tool for managing development environments by creating and destroying virtual machines. A simple LAMP stack provisioning example is demonstrated using Ansible on a Debian virtual machine hosted with Vagrant. The document then shows how to switch the Vagrant provider from VirtualBox to OpenStack.

1. Ansible & Vagrant

2. About Me
• Automation enthusiast
• Worked in corporate
environments
• Now co-founder of a small startup
company

3. Agenda
• Vagrant intro
• Simple LAMP provisioning setup
• Demo of provisioning on virtual box
• Switching vagrant provider to openstack

4. What is VAGRANT
• https://www.vagrantup.com/
• Manage development environments – up/destroy machines
• Works with different virtualization providers
• “Easy” ruby syntax
• Supports different provisioners

5. Our Simple LAMP
• Linux – Debian box image
• Apache with PHP and memcached
• MySQL / MariaDB
• Deploy application and load database from
a git repo

6. Ansible highlights
• apt
• Git
• Templates
- name: ensure apache is installed
apt: name=apache2 state=present
- git: repo=git@github.com/wiki.git dest=/var/www/site/
accept_hostkey=yes
- copy: src=templates/site.conf
dest=/etc/apache2/sites-enabled/site.conf

7. Ansible highlights
• MySql DB – import
• Notify
- name: create wiki app db
mysql_db: name=wikidb state=import
target=/var/www/site/wikidb.sql
handlers:
- name: restart apache
action: service name=apache2 state=restarted

8. Vagrant Ansible provisioner
• Pass variables (facts) to the playbook
• Vagrant specific – like IP
config.vm.provision 'ansible' do |ansible|
ansible.playbook = 'ansible/playbook.yml'
ansible.verbose = 'vvv'
ansible.extra_vars = {
ans_vm_priv_ip: vm_priv_ip
}
end

9. Switch the provider to
OpenStack
vagrant plugin install vagrant-openstack-provider
2. VM is booted
1. Create VM (up)
3. Provision VM over ssh

10. OpenStack provider
Vagrantfile
config.vm.provider :openstack do |os|
os.openstack_auth_url =ENV['OS_AUTH_URL']
os.tenant_name=ENV['OS_TENANT_NAME']
os.username = ENV['OS_USERNAME']
os.password = ENV['OS_PASSWORD']
os.floating_ip_pool = ENV['OS_FLOATING_IP_POOL']
os.flavor = ENV['OS_FLAVOR']
os.image = ENV['OS_IMAGE']
end
