    Addressing Challenges in Transitioning from IPI to ABI Installation

    In this post, we share how to deploy an entire Openshift Container Platform (OCP) cluster on a single baremetal server using the Assisted - Agent Based Installer (ABI) in a virtual environment with Libvirt VMs nodes. We highlight the benefits of ABI installation compared to the Installer Provisioner Infrastructure (IPI) installation that was our de-facto method.

    Networking Considerations for Distributed Deployment of Libvirt/KVM-Based OCP Clusters

    In previous blog posts, we have learned about the OCP on Libvirt project and the benefits it brings to us, with regards to the flexible deployment of OCP clusters where the nodes are virtual machines deployed on KVM. However, we have only covered the case of one single physical server. Can we use multiple physical servers to set up a lab with multiple, distributed deployment on Libvirt-based OCP clusters? The answer is yes! And we will explain the main requirements and challenges in terms of networking in this blog post.

    Using DCI to Easily Install an OpenShift Libvirt Cluster on a Single Baremetal Server

    This post is a tutorial on how to install a standard three-masters and two-workers OpenShift cluster on one powerful baremetal server. The idea is to first create all required virtual machines and networks using libvirt KVM driver, and then install OpenShift on that virtual cluster using DCI.

    SNO deployments with DCI under the hood

    Single Node OpenShift (SNO) was introduced officially in OCP 4.9, available documentation describes the ways to deploy it using Assisted Installer through the Red Hat portal in order to generate an ISO and install it using virtual media or ACM. This article illustrates how we leverage some of those features and highlights the most relevant aspects of the installation using DCI Openshift Agent.
