This role has been tested with three different versions of RHEL, this is 8.5, 8.6 and 9. You need to download the original iso file from Red Hat and store it in your target host, remember to define all the mandatory variables, including the full path to the original Red Hat iso file.
You only need to give values to all of the variables (some of these are optional):
#Directories and files
my_original_iso_full_path: /ISO-files/rhel-8.5-x86_64-dvd.iso
my_custom_iso: /ISO-files/my_custom.iso
my_working_dir: /tmp/working-dir
my_mnt_dir: /tmp/mnt-dir
#General iso configuration
my_system_language: en_US
my_keyboard_layout: es
my_time_zone: Europe/Paris
my_root_pass: redhat
#Networking options for iso file
my_network_bootprotocol: dhcp #Mandatory variable, options are "dhcp" or "static"
my_hostname: testhostname #Optional
my_netdevice: eht1 #Optional, only to be used if my_network_bootprotocol is "static"
my_ip: 192.168.1.23 #Mandatory when my_network_bootprotocol is "static"
my_netmask: 24 #Optional, only to be used if my_network_bootprotocol is "static"
my_gateway: 4.5.6.7 #Optional, only to be used if my_network_bootprotocol is "static"
my_dns_server: 8.8.8.8 #Optional, only to be used if my_network_bootprotocol is "static"
#Optional Red Hat CDN user and password for registering with Insights
my_rhn_user: myuser
my_rhn_pass: mypassword
#Optional, users to be created. You can add as many users as you want by growing the dictionary with the same structure
#Every entry on the dictionary must have "name" and "password" fields, optionally you can define additional groups for the user with the "groups" field (see example below)
my_users:
- name: ansible
password: redhat
groups: wheel
- name: preciado
password: redhat
groups: wheel
- name: pablo
password: redhat
Once you know all the values for your variables just write a simple playbook calling the role and defining the variables, such as the one you can find in the "example.yml" file.
