🔰 packer-rhel-vsphere-horizon-iso

This repo builds automatically RHEL VM templates (RHEL 22.04) for VMware vSphere and Horizon environment using Hashicorp's Packer.

RHEL ISO files gets downloaded from vCenter Datastore.

📚 How to use this repo

🔧 Pre-requesites

Download or git clone https://github.com/rebelinux/packer-rhel-vsphere-horizon-iso this repo and make sure you have Packer Version 1.8.5 or later installed. If you don't know Packer, it's a single commandline binary which only needs to be on your PATH.

Step 1: Adjust variables

Rename the file variables.auto.pkrvars.hcl.sample to variables.auto.pkrvars.hcl and adjust the variables for your VMware vSphere environment. Some documentation on each variable is inside the sample file.

mv variables.auto.pkrvars.hcl.sample variables.auto.pkrvars.hcl
nano variables.auto.pkrvars.hcl

Option 1: Local Horizon Agent File (Default)

Copy the Horizon Agent installation file to the ./files/ folder:

[rebelinux@rebelpc packer-rhel-vsphere-horizon-iso]$ ls -alh files/
total 127M
-rw-r--r-- 1 0 Apr 13 21:20 Place_Here_Horizon_Agent_Files.txt
-rw-r--r-- 1 127M Apr 10 08:31 "VMware-horizonagent-linux-x86_64-2303-8.9.0-21434177.tar.gz"
[rebelinux@rebelpc packer-rhel-vsphere-horizon-iso]$

Option 2: Use vCenter as a Web Server to host Horizon Agent File

Save the Horizon agent installation files to a staging Datastore

Get the Horizon agent file URL from the Browse datastores in the vSphere inventory

Next, uncomment line (292:296) and paste the vCenter URL like the provided example:

  provisioner "shell" {
   inline = [
     "curl -k --user '${var.vsphere_username}:${var.vsphere_password}' -X GET -o ./${var.horizon_agent_file} --output-dir '/tmp/' 'https://vcenter-01v.lab.local/folder/ISO%2fVMWARE%2fHorizon/VMware-horizonagent-linux-x86_64-2303-8.9.0-21434177.tar.gz?dcPath=PHARMAX-VSI-DC&dsName=HDD-VM-ISO-LOW-PERF'" 
     ]
  }

Step 2: Init Packer

Init Packer by using the following command. (Spot the dot at the end of the command!)

packer init .
packer validate .

Step 3: Build a VM Template

To build a VM template run one of the provided build-scripts. For example to build a RHEL 9.1 template run:

./build-rhel9.sh

If you are on a Windows machine then use the build-rhel9.ps1 files.

./build-rhel9.ps1

💻 Optional: Template default credentials

The default credentials after a successful build are Username: godadmin Password: godadmin

If you would like to change the default credentials before a packer build, then you need to edit the following files:

variables.auto.pkrvars.hcl (Line 41:49)

To generate an encrypted password use the following command:

mkpasswd -m SHA-512 --rounds=4096
