Using single-node Red Hat OpenShift clusters

A single-node cluster in Red Hat® OpenShift® consists of a single control plane node that is configured to run workloads. This configuration offers both control node and worker node functions, so you can deploy a smaller Red Hat OpenShift environment with or without dependence on a centralized management cluster. A single-node cluster can run autonomously when needed, which is useful for resource-constrained environments, demos, proofs of concept, or on-premises deployments.

By deploying a single-node cluster, you can experience the benefits of Red Hat OpenShift in a more compact environment that requires fewer resources. This cluster provides an efficient way to test new features or applications in a controlled environment. However, a single-node Red Hat OpenShift cluster lacks high availability, so it might not be suitable for mission-critical workloads that require constant uptime.
