Description

A Chef cookbook (beta) that builds a PXE appliance for Cisco UCS bare-metal deployment. This cookbook acts as the stage 2 phase for DC Automation.
As of now, the recipes are tied specifically towards the workflow defined by ucs or ucs-solo cookbooks.

Requirements

The PXE appliance is currently tested on Ubuntu 12.04.1 LTS. Other platform OSs as well as target OS's will be supported in the future.

Supported Targest OS Environments:

Ubuntu 12.04.1 LTS

Usage

Follows a convention. include_recipe considered harmful and therefore we do not use it as part of our philosophy.
We prefer more explicit ways to do things forcing us to declare all dependencies when orchestrating.

The run_list order using knife:

1. Install packages

knife node run_list add  recipe[ucs-pxe::default]
knife ssh name: -x  -P  "sudo chef-client"

2. Setup the databags needed for generating the custom dhcpd.conf

knife node run_list remove  recipe[ucs-pxe::default]
knife node run_list add  recipe[ucs-pxe::databag]
knife ssh name: -x  -P  "sudo chef-client"

3. Setup dhcpd.conf based on mac addresses of all assigned service profiles

knife node run_list remove  recipe[ucs-pxe::databag]
knife node run_list add  recipe[ucs-pxe::dhcpd]
knife ssh name: -x  -P  "sudo chef-client"

4. Build target OS environment to be deployed.

knife node run_list remove  recipe[ucs-pxe::dhcpd]
knife node run_list add  recipe[ucs-pxe::ubuntu]
knife ssh name: -x  -P  "sudo chef-client"

5. Reboot Service Profile(s). The install should begin.

6. The system halts after installation is complete.

ToDo

1. Reciple for toggling boot policy to boot from disk to move towards Stage 3 - service provisioning.
