Custom system image creation with Composer available as a Technology Preview
The Composer tool enables users to create customized RHEL images. Starting with Red Hat Enterprise Linux 7.6, Composer is available in the Extras channel as a Technology Preview in the lorax-composer package.
With Composer, users can create custom system images which include additional packages. Composer functionality can be accessed through a graphical user interface in Web Console, or with a command line interface in the
composer-cli tool. Composer output formats include, among others:
- ISO disk image
- qcow2 file for direct use with a virtual machine
- file system image file
To install Composer, start it as a Web Console plugin and open the page in browser:
# yum install lorax-composer cockpit-composer composer-cli # systemctl start lorax-composer # systemctl start cockpit $ gnome-open http://localhost:9090/
To automatically start Composer after reboot:
# systemctl enable lorax-composer.socket # systemctl enable cockpit.socket
