Managing Sensitive Assets Within Image Mode for Red Hat Enterprise Linux

Andrew Block

Aside from naming and versioning, managing sensitive assets, like credentials, is one of the more challenging aspects in technology. So, why is it so difficult? Well, to start off. What may be considered a sensitive asset to one individual or organization may not be the same as another. Also, given that there are so many different ways that sensitive assets can be managed, there is no universally accepted method available.
The challenges that encompass how sensitive assets are handled also apply to image mode, a new method that enables building and deploying Operating Systems using similar tools and approaches as any other traditional container. In this article, we will discuss the types of sensitive assets that apply to image mode for RHEL specifically and how to design appropriate workflows to incorporate secure practices within all phases, from build and deployment to runtime.

Integrating a VMDK produced with image mode for RHEL into vSphere

Andrew Block

While the VMDK format is open source, they are traditionally used within the VMware family of solutions, such as VMware Workstation and VMware vSphere. In this post, we will describe how the previously created VMDK disk can be used as the basis for a virtual machine hosted in a VMware vSphere environment.

Creating a VMDK using image mode for Red Hat Enterprise Linux

Andrew Block

Image mode for Red Hat Enterprise Linux (RHEL) combines the benefits and methodologies of container technologies with the ability to operate within traditional virtual machine environments. By enabling a familiar container image assembly process that supports several popular output types, end users have the flexibility to choose where and how they want to operate.

One of the supported output formats is a Virtual Machine Disk (VMDK), which is commonly used within VMware’s supported virtualization platforms, like vSphere, but support is also available elsewhere, including VirtualBox. Bridging the gap between traditional operating environments and cloud-native technologies is one of the benefits that image mode provides. Over the course of this series, we will describe the process for creating image mode for RHEL-based bootc images for use within VMware environments, that, when included within reusable templates, will enable a consistent method for delivering virtual environments. Plus, several different methods will also be provided that illustrate how the generation of the various assets can be automated to create a repeatable factory for delivering bootc images to meet the demands of today and tomorrow.
