# RHEL9 Foreman Guide



      



> - In this Guide i will show you how to install Forman with puppet, katello and discovery plugin.

> - You will also learn how to install and setup DHCP- and TFTP-Server.

> - I will also show you how to setup Foreman and how to use the Foreman Boot Image via PXE.

> - You will be ready to discover and provision your physical servers and workstations after following this Guide.

 

## 1. [Knowledge Base](https://ji-podhead.github.io/RHEL_9_Foreman_Guide/knowledge%20base)

> - here we explain:

>	  -  how tftp and dhcp works 

>   -  how the pxe boot process works

>	  -  how the foreman smartproxy works

>   -  Lifecycle Management

>      - what is it?

>      - puppet & katello roles

## 2. [Install Foreman (with katello, discovery-plugin, and local dhcp/tftp)](https://ji-podhead.github.io/RHEL_9_Foreman_Guide/installation%20(katello%2Cdiscovery%2Cdhcp%2Ctftp))

> - just the installation process

## 3. [Discovery and Provisioning](https://ji-podhead.github.io/RHEL_9_Foreman_Guide/discovery%20and%20provisioning)

> - we discover our host using the Boot Image

> - we set up Hostgroups, subnets, etc

> - we finally provision our discovered host

## 4. [install and setup libvirt in Foreman](https://ji-podhead.github.io/RHEL_9_Foreman_Guide/libvirt)

> - we install libvirt

> - we setup libvirt as compute resource

> - boot intoo container/vm

## 5. [Proxmox](https://ji-podhead.github.io/RHEL_9_Foreman_Guide/proxmox)

>  - we install proxmox inside a vm using kvm&libvirt 

>  - we setup proxmox as a compute resource

## 6. [Install Foreman with external DHCP & DNS](https://ji-podhead.github.io/RHEL_9_Foreman_Guide/nestedVM_with_external_DHCP%26DNS)

>  - we install foreman inside a nested VM

>  - we set up our DHCP & DNS for Dynamic Updates using RNDC 

>  - we configure our DHCP to share its leases using omapi(HMAC-MD5) key and NFS

>  - we configure Foreman to manage our external DNS by importing the RNDC key

>  - we configure Foreman to manage our external DHCP by using remote-isc-key flag and our omapi key   

## 7. [diskless pxe-boot using zfs](https://ji-podhead.github.io/RHEL_9_Foreman_Guide/diskless_pxe_using_zfs) *(under construction)*

> - we create a zfs tank inside proxmox

> - we create a wm inside proxmox and move the storage to our zfs tank *(optional)*

> - we create a automatic backup-plan for the wm *(optional)*

> - we create a pxe template inside foreman to pxe-boot diskless using the zfs tank storage
