infra_server_pxe_setup

Simple role to setup a PXE Boot Server supporting the following configurations:

• Install CentOS 7 x64 with Local Repo
• Install CentOS 7 x64 with http://mirror.centos.org Repo
• Install CentOS 7 x64 with Local Repo using VNC
• Install CentOS 7 x64 with Local Repo using Kickstart
• Boot from local drive

Is it based on the following blogs:

https://www.tecmint.com/install-pxe-network-boot-server-in-centos-7/
https://www.tecmint.com/multiple-centos-installations-using-kickstart/

NOTE: Kickstart implementation is experimental. The anaconda-ks.cfg template needs to evolve so it can be customized using variables. At the moment of writing it supports one sample configuration and not any machine configuration based on user input. User Management, Network Information, Disk Management and Packages need to be parameterized.
