Red Hat Enterprise Linux 8 ships a new tool, called Image Builder, that allows you to create custom Red Hat Enterprise Linux system images in a variety of formats. These include compatibility with major cloud providers and virtualization technologies available in the market. As a result, it enables you to quickly spin up new Red Hat Enterprise Linux (RHEL) systems in different platforms, according to your requirements.
In this article, we’ll show how to set up Image Builder in Red Hat Enterprise Linux 8 and create a couple of images to test its capabilities. Red Hat recommends running Image Builder on its own dedicated virtual machine.
To follow this tutorial, you will need a virtual machine running Red Hat Enterprise Linux 8 where we’ll install Image Builder. This virtual machine needs to be subscribed and have access to the Red Hat Enterprise Linux 8 packages repositories. We’ll not cover Red Hat Enterprise Linux 8 installation in this post. For more information, consult the product documentation.

There are several things that don’t change, however. Some of the concerns that have been with us since before the dawn of time2 include:
- Making developers as productive as possible
- Balancing productivity with governance and compliance
- Delivering software predictably and in a timely manner
- Making software as robust as possible
- Prioritizing usability and accessibility
But beyond these goals, there are three factors that are always in flux:

If you’re running Red Hat Enterprise Linux server on Microsoft Azure, you may want to shut down and deallocate the VM using commands inside of the VM itself for automation or just for convenience. On Azure, if you shut down the VM by using
shutdown -h or another OS command, it will stop but not deallocate it. The stopped VM is still using resources and will continue to incur compute charges. To avoid that, this article shows how a VM can shut itself down and deallocate its resources using the Azure CLI 2.0.
