description	Use this skill when you need to deploy HyperShift clusters on OpenStack infrastructure with proper flavor selection and network configuration

HyperShift OpenStack Provider

This skill provides implementation guidance for creating HyperShift clusters on OpenStack, handling OpenStack-specific requirements including credentials, networking, and flavor selection.

When to Use This Skill

This skill is automatically invoked by the /hcp:generate openstack command to guide the OpenStack provider cluster creation process.

Prerequisites

• OpenStack CLI configured with appropriate credentials
• OpenStack project with sufficient quotas
• External network configured for floating IPs
• HyperShift operator installed and configured

OpenStack Provider Overview

OpenStack Provider Peculiarities

• Requires OpenStack credentials: Must have valid clouds.yaml or environment variables
• Floating IP networks needed: External network access for cluster API
• Flavor selection critical: Instance flavors affect performance and cost
• Custom images may be required: RHCOS images for worker nodes
• Network topology affects routing: Proper network configuration essential

Implementation Steps

Step 1: Interactive Parameter Collection

Required Parameters:

1. OpenStack Credentials

   🔹 **OpenStack Credentials**: Path to OpenStack credentials file?
      - Usually clouds.yaml format
      - Example: /home/user/.config/openstack/clouds.yaml
   

2. External Network

   🔹 **External Network ID**: OpenStack external network UUID?
      - Required for floating IP allocation
      - Find with: openstack network list --external
   

3. Flavor Selection

   🔹 **Node Flavor**: Choose instance flavor:
      - m1.large (4 vCPU, 8GB RAM) - Standard workloads
      - m1.xlarge (8 vCPU, 16GB RAM) - Performance workloads
      - [default: m1.large]
   

Step 2: Generate Command

Standard Configuration:

hypershift create cluster openstack \
  --name openstack-cluster \
  --namespace openstack-cluster-ns \
  --openstack-credentials-file /path/to/clouds.yaml \
  --openstack-external-network-id <external-network-uuid> \
  --openstack-node-flavor m1.large \
  --base-domain example.com \
  --pull-secret /path/to/pull-secret.json \
  --release-image quay.io/openshift-release-dev/ocp-release:4.18.0-multi

Error Handling

External Network Not Found

External network with ID "<uuid>" not found.

List available external networks:
  openstack network list --external

Ensure network has proper routing configuration.

Flavor Not Available

Flavor "m1.large" not available in this OpenStack deployment.

List available flavors:
  openstack flavor list

Choose appropriate flavor for your workload requirements.
