Packer/Ansible - Create a RHEL 7.5 image and upload it to RHEV Manager

This example create a qcow2 RHEL7.5 image with packer and ansible and upload it to your RHV Engine in order to create a new template.

The image could be created based on a packer / cloud init or packer / kickstart configuration and you can apply any ansible roles/playbooks that it could be useful for you, this example use a simple ansible role to register a RHEL box, update all packages and configure a simple motd file.

Paternity

This repo is a shamelessly fork from Tinsjourney, modified to create a Red Hat Enterprise Linux qemu box based on cloud-init or ks configuration. So all gratitude should go to him, and all criticism to myself.

Requirements

The following software must be installed/present on your local machine before you can use Packer to build the Vagrant box file:

• Packer
• Ansible
• [Red Hat Subcription] If you don't, create an account

Usage

• Make sure all the required software is installed.
• cd to the packer-rhel-7 directory
• Copy RHEL's ISO images in iso/ directory iso's rhel-server-7.5-x86_64-dvd.iso rhel-server-7.5-x86_64-kvm.qcow2 .
• Edit vars/rhel75_cloud_vars.json (based on cloud init) or vars/rhel75_ks_vars.json (based on kickstart) file, check if iso_urls and iso_checksum match your RHEL iso.
• Create ansible variables file variables.yml, with your RHSM and RHV Engine informations

• Run create_cloudinit_image.sh script for a cloud-init based image (modify cloud-init/user-data.txt if you desired) :

    $ create_cloudinit_image.sh

• or a create_kickstart_image.sh script for a kisckstart based image (modify http/ks.cfg if you desired) :

    $ create_kickstart_image.sh

• Finally, we will upload the image to RHV Engine with oVirt.image-template role

    $ ansible-galaxy install -r requirements.yml
    $ ansible-playbook ansible/rhv_create_template.yml

There's another ovirt role vm-infra to create new VM from a template with ansible as well.
