Razor Vagrant Lab

Initial Setup

Download and install the following on your workstation:

  1. VirtualBox (currently tested on version 4.2.4 on Mac)
  2. VirtualBox Oracle VM VirtualBox Extension Pack (needed for PXE booting support)
  3. Vagrant (package install, version 1.1.0 or higher)
  4. vagrant-berkshelf plugin (needed to resolve and use cookbooks)
  5. vagrant-omnibus plugin (needed to install Chef on the Vagrant VMs)

Note: please ensure that VirtualBox's DHCP server is not running, otherwise the razor client nodes may recieve IP address in the 192.168.0.0. range:

VBoxManage list dhcpservers                          # should show no dhcp servers
VBoxManage dhcpserver remove --netname NETWORK_NAME  # otherwise, run this

Now clone this project repo to your workstation.

All you should have to type in the project directory is:

$ ./script/bootstrap

Follow any directions given and possibly re-run the bootstrap script.

Usage

Starting The Razor Node

$ vagrant up razor

Starting The Chef Server (Optional)

$ vagrant up chef

Starting The Puppet Master Server (Optional)

$ vagrant up puppet

Setting Up A Sample Razor Configuration

To see Razor in action, several "slices" have to be set up in order to execute a policy on a node. Several quickstart examples have been provided which will set up all nodes to install Ubuntu 12.04 LTS. To run the script, login to the razor node and become the root user:

$ vagrant ssh razor
$ sudo su - root

Chef Broker Configuration

This will set up a Chef broker to run after nodes are provisioned. Run it from the Vagrant-provided mount:

$ /vagrant/contrib/razor_for_chef_ubuntu.sh

For a list of configuration overrides (such as the ISO download URL), please run:

$ /vagrant/contrib/razor_for_chef_ubuntu.sh help

Puppet Broker Configuration

This will set up a Puppet broker to run after nodes are provisioned. Run it from the Vagrant-provided mount:

$ /vagrant/contrib/razor_for_puppet_ubuntu.sh

For a list of configuration overrides (such as the ISO download URL), please run:

$ /vagrant/contrib/razor_for_puppet_ubuntu.sh help

Brokerless Configuration

This will set up a basic setup with no brokers running. Run it from the Vagrant-provided mount:

$ /vagrant/contrib/razor_for_bare_ubuntu.sh

For a list of configuration overrides (such as the ISO download URL), please run:

$ /vagrant/contrib/razor_for_bare_ubuntu.sh help

Starting A Razor Client Node

$ vagrant up node1

There are by default 3 nodes available (i.e. node1, node2, node3), but you can set a higher/lower number by setting RAZOR_NODES=10 in your shell environment:

$ export RAZOR_NODES=10
$ vagrant status
Current VM states:

razor                    running
chef                     not_created
puppet                   not_created
node1                    not created
node2                    not created
node3                    not created
node4                    not created
node5                    not created
node6                    not created
node7                    not created
node8                    not created
node9                    not created
node10                   not created

This environment represents multiple VMs. The VMs are all listed
above with their current state. For more information about a specific
VM, run `vagrant status NAME`.

Starting The Entire Cluster

$ vagrant up

Vagrant Base Boxes

The base boxes were built with the VeeWee gem. The Razor and Puppet nodes are using an Opscode provided Ubuntu 12.04 base box, built from VeeWee definitions in a project called Bento. To simulate unprovisioned bare metal instances, a special base box called blank-amd64 was created and was built from VeeWee definitions in a project called veewee-definitions.
