Description

  • Add 'patch' verb to ClusterRole for statefulsets resource
  • Required for versionless Patch operation used in auto-scaling
  • Eliminates optimistic concurrency errors during scale operations
  • Bump chart version to 1.4.1

This change supports the improved scaling logic in mc-router that uses strategic merge patches instead of Get+Update, avoiding resourceVersion conflicts when StatefulSets are modified concurrently.

Contributor guide

Research direction
Locate the ClusterRole definition in the Helm chart templates (likely under templates/rbac.yaml) and add 'patch' to the verbs list for the statefulsets resource. Then increment the chart version in Chart.yaml from 1.4.0 to 1.4.1.
