StarlingX Deployment in Virtualized Environments

A StarlingX system can be installed in a variety of platforms with the following deployment options:

• Standard Controller
  • Dedicated Storage
  • Controller Storage
• All-in-one
  • Duplex
  • Simplex

Deployment options uses a variety of configurations based on 3 node identities:

• Controller
• Storage
• Compute

Standard Controller :: Dedicated Storage

The software installation workflow for an initial Ceph-backed block storage on dedicated storage nodes is:

• Controller-0 Installation and Provisioning
• Controller-1 / Compute Host / Storage Host Installation
• Controller-1 Provisioning
• Provider Network Configuration
• Compute Host Provisioning
• Storage Host Provisioning

Standard Controller :: Controller Storage

The software installation workflow for an initial LVM-backed block storage on controller nodes is:

• Controller-0 Installation
• Controller-0 and System Provisioning
• Controller-1 / Compute Host Installation
• Controller-1 Provisioning
• Compute Host Provisioning

All-in-one :: Duplex

The software installation workflow for two combined controller / compute nodes is:

• Controller-0 Installation and Provisioning
• Controller-1 Installation and Provisioning

All-in-one :: Simplex

The software installation workflow for a single combined controller / compute node is:

• Controller-0 Installation and Provisioning

Virtualization Environments

The available virtualization products where StarlingX has been deployed are:

• VirtualBox
• Libvirt/QEMU

Directory: libvirt

Deployment under Libvirt/QEMU uses a set of xml files to define the node identity:

• Controller All-in-one
• Controller
• Compute
• Storage

These nodes are used to create the virtual machines and the network interfaces to setup the StarlingX system:

• Setup Simplex
  • 1 Controller
• Setup Duplex
  • 2 Controllers
• Setup Controller Storage
  • 2 Controllers
  • 2 Computes
• Setup Dedicated Storage
  • 2 Controllers
  • 2 Computes
  • 2 Storages

Directory: virtualbox

Deployment under VirtualBox uses a set of parameters passed via terminal to define the StarlingX system:

• Controller All-in-one
• Controller
• Compute
• Storage

These parameters are used to create the virtual machines, the network interfaces and completly install StarlingX.

The script will create a number of virtual machines depending on the setup chosen:

• Setup Simplex
  • 1 Controller
• Setup Duplex
  • 2 Controllers
• Setup Controller Storage
  • 2 Controllers
  • 2 Computes
• Setup Dedicated Storage
  • 2 Controllers
  • 2 Computes
  • 2 Storages

Directory: provision

A set of scripts are provided to automate the provisioning of data interfaces and local storage resources for the compute function for StarlingX Duplex or Simplex.
