 {sno-caps} clusters reduce the host prerequisites for deployment to a single host. This is useful for deployments in constrained environments or at the network edge. However, sometimes you need to add additional capacity to your cluster, for example, in telecommunications and network edge scenarios. In these scenarios, you can add worker nodes to the single-node cluster.
