Error: numCoresPerSocket Variable Schema Validation

Products

• VMware Telco Cloud Automation

Issue/Introduction

Upgraded TCA from version 3.0 to 3.2. While attempting to create a Workload Cluster using the TCA API, the following validation errors were encountered:

• controlPlane.machine.numCoresPerSocket is not defined in the variable schema for the controlPlane object

• worker.machine.numCoresPerSocket is not defined in the variable schema for the worker object

Environment

3.2

Cause

The tbr-bom is coupled with specific Kubernetes versions and an expected ClusterClass version 

Resolution

In the cluster.json file, change 

from:

topology
  class: tkgvsphere-default-v1.1.0

to:

topology
  class: tkgvsphere-default-v1.2.0 

Additional Information

• TBR is not just about Kubernetes version—it also pins the ClusterClass version.

• You cannot freely mix and match TBRs and ClusterClasses. If you pick a TBR, you're also choosing the ClusterClass version that comes with it.

• The TBR acts as a single source of truth for deploying consistent clusters in TCA.
