rhel_ovirt_template

This repo contains an Ansible role that builds a RHEL/CentOS VM template from an ISO file on Ovirt/RHV. You can run this role as a part of CI/CD pipeline for building RHEL/CentOS templates on Ovirt/RHV from an ISO file.

Note: This role is provided as an example only. Do not use this in production. You can fork/clone and add/remove steps for your environment based on your organization's security and operational requirements.

Requirements

You need to have the following packages installed on your control machine:

mkisofs
genisoimage

You need to enable qemu_cmdline hook on your RHV/Ovirt environment, this is required to enable attaching multiple iso files. Follow the instructions documented here:

https://www.ovirt.org/develop/developer-guide/vdsm/hook/qemucmdline.html

Before you can use this role, you need to make sure you have RHEL/CentOS install media iso file uploaded to a iso domain on your RHV/Ovirt environment.

Role Variables

A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.

Dependencies

Import ovirt.ovirt collections.

A list of roles that this role utilizes:

oatakan.rhn

oatakan.rhel_template_build

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
