Chapter 2.  Installing Image Builder

Before using Image Builder, you must install Image Builder in a virtual machine.

2.1.  Installing Image Builder in a virtual machine

To install Image Builder on a dedicated virtual machine, follow these steps:


  • Connect to the virtual machine.
  • The virtual machine for Image Builder must be installed, subscribed, and running.


1. Install the Image Builder and other necessary packages on the virtual machine:
  • lorax-composer
  • composer-cli
  • cockpit-composer
  • bash-completion
# yum install lorax-composer composer-cli cockpit-composer bash-completion
2. Enable Image Builder to start after each reboot:
#  systemctl enable lorax-composer.socket
#  systemctl enable cockpit.socket
The lorax-composer and cockpit services start automatically on first access.
3. Configure the system firewall to allow access to the web console:
# firewall-cmd --add-service=cockpit && firewall-cmd --add-service=cockpit --permanent
4. Load the shell configuration script so that the auto-complete feature for the composer-cli tool starts working immediately without reboot:
$ source /etc/bash_completion.d/composer-cli
