HOWTO Light and Zero Touch Deployments of OS 12

Note: Options for how to deploy IGEL OS in either a light touch or zero touch manner.

OS Creator – Unattended

UMS PXE

  • How to Deploy IGEL OS 12 with PXE
  • More scalable than USB
  • Zero touch after device is PXE booted
  • Requires internet access
  • Medium-high difficulty to setup
  • Lots of moving parts. (DHCP, tftp server, web server, UMS json)

UMS PXE via Docker Container on IGEL OS

IGEL OS 12 Docker ProxyDHCP PXE Server

Microsoft Deployment Toolkit or MDT

  • More scalable than USB - requires device to pxe boot
  • Can re-use existing WDS/MDT infrastructure
  • Fewer moving parts (WDS, MDT, shared folder)
  • Low/Medium difficulty to setup
  • Not as robust as SCCM/MECM
  • Not yet a KB article or supported method

SCCM with NO IGEL Plugin - Option 1

  • You control the how and where
  • The image file does not need to be in the boot media, you control where you run it from
  • You keep your existing boot media, you only add files to it, if you want or need to
  • If you use something like 1E Nomad or Adaptiva today, you can use it for deployment going forward
  • How many packages you create is your choice

SCCM with NO IGEL Plugin - Option 2

  • Download the OS12 Base System Deployment Tool for SCCM
  • Extract all the utilities and the OS image from it and put them in a folder on your network
  • Inject dd.exe from the folder into your existing boot media - Optional
  • Create deployment tool packages
  • Create your own task sequences
  • Test the task sequences and deploy
  • Not officially supported by IGEL but works incredibly well

Automatic Device Registration

  • So, you deployed the OS, now what?

Default Directory Rules

  • So, your device is registered and licensed, now what?

IGEL OSCW Enhanced - Under the Hood

OSCW cannot register with UMS through ICG and so you can't do the normal OCSW procedure (register, apply profile, send conversion command).

Here is a method to use the unattended OSC .iso

Summary of steps:

  • Install OSCW
  • Rename the osc-12.7.5.iso to osc.iso (Make sure this is the unattended version of the ISO you created earlier)
  • Copy the osc.iso into the C:\OSC folder
  • Rename grub.cfg to grub.cfg.old
  • Rename osc.cfg to grub.cfg
  • Restart the device

The device will boot using the GRUB boot loader which will trigger the IGEL installation from the ISO.
