Hotwire Rapid Build & Deploy System

Background

  1. Client awakens, and makes a broadcast request for an IP Address, supplying its MAC Address. In the request it makes it clear that it is a PXE client, and not a standard DHCP client, along with other info such as hostname. All this is ofcourse done by the Network Card designated to PXE boot in the BIOS.

  1. The DHCP Server picks this request, acknowledges that it is indeed a PXE client, and sends it back some good info on what to do next... 
      class "pxeclients"{
    match if substring(option vendor-class-identifier,0,9) = "PXEClient";
    next-server 192.168.16.10;
    filename "linux-install/pxelinux.0";
  }
    ...a filename to request from the supplied tftp server.

  1. The client now makes a TFTP request for the file described by the DHCP(PXE) Server, directed at the TFTP server. 
      linux-install/pxelinux.0
  1. The TFTP server sends this to the client.
  1. This file that the TFTP file sends is a small kernel, which adheres to standard the PXE protocol, and once loaded by the client, will ask the tftp for a filename which is its hex-encoded-ip... 
      linux-install/pxelinux.cfg/C0A81035
  1. The client downloads that file, and on inspection of that file, it discovers what the kernel to boot is, kernel options specific to that kernel... 
           kernel RedHat/4.0/ES/x86_64/current/vmlinuz

       append ksdevice=eth1 \
              initrd=RedHat/4.0/ES/x86_64/current/initrd.img \
              ks=http://153.107.13.21//kickme/kickstart.php
  1. The TFTP Server sends the kernel image back, and the client boots it with the kernel options appended, which in turn calls the kickstart script.
