Multi-node Requirements

• OpenStack Deploy
  
  • Do these tasks already include deployment of each type of node necessary?
    • etcd
    • k8 master
    • k8 worker
    • gluster
• Kubernetes Deploy
  • This should be ready for multi-node, right?
• Gluster Deploy
  • What types / how many of each type of nodes?
• NDS Labs Deploy
  • What types / how many of each type of nodes?
    • single node for gui + apiserver?
    • one node each for gui / apiserver?
