If you weren’t lucky enough to attend the recent Red Hat Summit or you went but couldn’t make it to all the container-related sessions, worry not. We teamed up with Scott McCarty, Principal Technology Product Manager–Containers at Red Hat, to bring you an overview of what you missed.
Choosing the right container base image for your applications
The Red Hat Universal Base Image (UBI) gives you three options for building containers with the full power of Red Hat Enterprise Linux (RHEL) underneath. The goal is to create the smallest possible image that fully supports your application. You select a base image depending on the application you’re packaging in a container. For example, if you have a Golang or .NET application, all of that application’s dependencies are built in. That means you can use the minimal image (
ubi-minimal), which contains
microdnf, a package manager that only supports install, update, and remove functions. It also includes, well, a minimal set of tools.

Red Hat Enterprise Linux 8 comes with modules as a packaging concept that allows system administrators to select the desired software version from multiple packaged versions. This article will show you how to manage Perl as a module.

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.

TL;DR Of course we have Python! You just need to specify whether you want Python 3 or 2 as we didn’t want to set a default. Give
yum install python3 and/or
yum install python2 a try. Or, if you want to see what packages we recommend, use
yum install @python36 or
yum install @python27. Read on for why.

Have you tried the Red Hat Enterprise Linux 8 (RHEL8) Beta yet? Read on to learn how to stand up a LAMP stack on top of RHEL8 Beta quickly, and play around with new features built into the operating system.
A LAMP stack is made up out of four main components, and some glue. The first main component in a LAMP stack is Linux. In my example, I’m using Red Hat Enterprise Linux 8 Beta for that, which gives me a secure operating system, a modern programming environment, and user-friendly set of tools to control it.
