Before you start This tutorial assumes you've got the CLI tools running. If you don't, please visit the Openstack command-line interface (CLI) installation commands tutorial. When building a cluster of instances on Fuga, you want to ensure that these instances are created on separate compute nodes in order to ensure the highest availability. When creating the instances via the Fuga dashboard, you have no way to control on which compute node your instance will be created and cluster nodes can be created on the same compute node.
