IBM/Red Hat: Red Hat Universal Base Images, OKD and OpenShift

  • Red Hat Universal Base Images for Docker users

    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.

    This situation was far from the truth because containers are not just about Docker anymore. Container runtimes, container images, registry servers, and other technologies related to the Linux container ecosystem are now standardized by the Open Container Initiative (OCI). Thanks to the OCI, you can develop a container using one tool and then run the same container using another tool. For example, Red Hat builds a container image using Buildah on RHEL 8, and then you run that container image using Docker on a Windows system.

    Another example would be you building a container image using Docker on a Mac system and then later you run that container image on a Red Hat Enterprise Linux 8 server with Podman.

  • Guide to Installing an OKD 4.4 Cluster on your Home Lab

    OKD is the upstream community-supported version of the Red Hat OpenShift Container Platform (OCP). OpenShift expands vanilla Kubernetes into an application platform designed for enterprise use at scale. Starting with the release of OpenShift 4, the default operating system is Red Hat CoreOS, which provides an immutable infrastructure and automated updates. OKD’s default operating system is Fedora CoreOS which, like OKD, is the upstream version of Red Hat CoreOS.

    Instructions for Deploying OKD 4 Beta on your Home Lab

    For those of you who have a Home Lab, check out the step-by-step guide here helps you successfully build an OKD 4.4 cluster at home using VMWare as the example hypervisor, but you can use Hyper-V, libvirt, VirtualBox, bare metal, or other platforms just as easily.

System76 Thelio Major Proves To Be A Major Player For Linux Workstations

For the past two months we have been testing the System76 Thelio Major and it's been working out extremely well with performance and reliability. The Thelio Major offering with options for Intel Core X-Series or AMD Ryzen Threadripper and resides between their standard Thelio desktop with Ryzen/Core CPUs and the Thelio Massive that sports dual Intel Xeon CPUs. The Thelio Major is the platform we have been using for all of our AMD Ryzen Threadripper 3990X testing and it's been working out great. The Thelio Major besides having Threadripper and Core X-Series CPU options can be configured with up to 256GB of RAM, up to two GPUs, and up to 46TB of storage for really yielding incredibly powerful Linux workstation performance potential.
