# 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_upgrade
- 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:

    # import ovirt.ovirt collections

      hosts: all
      gather_facts: False
      connection: local
      become: no
      vars:
        template_force: yes #overwrite existing template with the same name

        local_account_password: ''
        local_administrator_password: ''
        linux_distro_name: rhel_81 # this needs to be one of the standard values see 'os_short_names' var

        template_vm_root_disk_size: 10
        template_vm_memory: 4096
        template_vm_efi: false # you need to install efi file to use this, false should be fine in most cases

        ovirt_data_domain: '' # name of the data domain
        ovirt_export_domain: '' # name of the iso domain
        ovirt_iso_domain: '' # this is deprecated as of 4.3 you can omit if not used
        
        template_vm_network_name: ovirtmgmt
        template_vm_ip_address: 192.168.10.95 # static ip is required
