This configuration was designed to create a minimal OpenStack cluster using a Raspberry Pi 4 Model B without High Availability.
The provisioning process is executed on the Controller node. It creates a local registry on it using the registry script and deploys OpenStack services using the undercloud script.
The following diagram shows the distribution of OpenStack Kolla containers created by this configuration.
- Broadcom BCM2711, Quad core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz
- 4GB or 8GB LPDDR4-3200 SDRAM
Once Vagrant is installed, it's possible to deploy an OpenStack cluster on Virtual Machines.

| Name | Default | Description |
|---|---|---|
| OS_NUM_COMPUTE_NODES | 2 | Specifies the number of OpenStack compute nodes |
| OS_ENABLE_LOCAL_REGISTRY | true | Determines if a local registry will be deployed on the Controller node. This includes the Kolla build process |
| CPU | 4 | Number of vCPUS assigned to the Virtual Machine |
| MEMORY | 8 GB | Memory assigned to the Virtual Machine (Compute nodes use 4 GB ) |
