Learn to simplify on-premises OpenShift cluster expansion through automated node deployment techniques in this conference talk from DevConf.CZ 2025. Discover how to overcome the traditionally complex, time-consuming, and frustrating process of adding new nodes to both large production OpenShift clusters and small home-based OKD testing environments. Master the use of the oc command-line tool to generate ISO images that enable seamless, hands-free node deployment, particularly valuable when scaling clusters with multiple compute instances. Explore the mechanics of this new feature, including step-by-step ISO image creation and customization processes, and understand how to implement automatic cluster scaling with minimal operational overhead. Gain practical insights suitable for both experienced administrators managing enterprise environments and newcomers working with limited resources, helping reduce the complexity and frustration typically associated with on-premises cluster expansion tasks.
