description: An eight-machine Kubernetes cluster, appropriate for production. Includes a three-machine etcd and ceph-mon cluster, a Kubernetes master, three Kubernetes worker nodes and a Kubernetes worker with GPUs. The Ceph (Luminous) cluster uses three nodes for Ceph Monitors and a Ceph OSD in LXD containers on each worker machine. Two Ceph MDSs provide redundant shared Ceph File System.
