Red Hat Universal Base Images for Docker users

Red Hat Universal Base Images for Docker users

Red Hat Universal Base Images (UBIs) allow developers using Docker on Windows and Mac platforms to tap into the benefits of the large Red Hat ecosystem. This article demonstrates how to use Red Hat Universal Base Images with Docker from a non-Red Hat system, such as a Windows or Mac workstation.

Red Hat Enterprise Linux and Docker

When Red Hat Enterprise Linux (RHEL) 8 was released almost a year ago, and it came with lots of new features related to containers. The biggest ones were the new container tools (Podman, Buildah, and skopeo) and the new Red Hat Universal Base Images. There was also confusion because RHEL 8 dropped support for the Docker toolset. Some developers thought that they could not work with Docker anymore, and had to either migrate to a Red Hat-ecosystem Linux system such as CentOS or stay away from Red Hat customers.

Red Hat JBoss Developer Studio on MacOS X- an alternative setup

The  recommended steps for setting up the Red Hat JBoss Developer Studio (JBDS), on all supported platforms, are found here. The instructions are pretty straight-forward and it is enough to get started right away – as long as you have a suitable java SDK installed on your machine.

However, if I go along that path, I would later have to deal with the Java SDK updates to go along with the compatibility of the existing tools. Eventually, I may end up having to install multiple versions of the Java SDK.

This led me to look for other alternatives. I thought to myself, the Linux’y way to go would be to run the JBDS as a container and have it display on my Desktop. I figured that I already have the tools for such task: XQuartz as an X11 server, socat to relay the display ports, and my Red Hat Enterprise Linux (RHEL) virtual machine. Yey!

The following are the steps on how I got all these to work together.
