How to deploy a tenant on OpenStack

Type: How-to · Audience: Operator with OpenStack access

Overview

Create a Talos cluster on OpenStack using the OpenStack provider.

Prerequisites

• RezusCloud management plane running
• OpenStack credentials configured (OS_* env vars on the deployment)
• A Glance image named talos-<version>-openstack-amd64
• An external network, flavor, and subnet

Steps

1. Create the tenant with the desired versions.

2. Create a node group with providerClass: "openstack:SCS-4V-8-50" (or your flavor name) and provider config:

   {
     "flavorName": "SCS-4V-8-50",
     "imageName": "talos-1.12.6-openstack-amd64",
     "extNetName": "ext-net"
   }
   

3. Watch reconciliation — same as OCI.

Verification

rezusctl get machines --cluster <name> --server $SERVER

Machines should show providerType: openstack.
