= About OpenShift on a single node
|
|
|
|
You can create a single-node cluster with standard installation methods. {product-title} on a single node is a specialized installation that requires the creation of a special Ignition configuration file. The primary use case is for edge computing workloads, including intermittent connectivity, portable clouds, and 5G radio access networks (RAN) close to a base station. The major tradeoff with an installation on a single node is the lack of high availability.
