Is it possible to automatically tag/label nodes based on ESXi host for workload distribution on vSphere in an OpenShift cluster deployed via Installer-Provisioned Infrastructure (IPI) on VMware ESXi

Solution Verified - Updated -

Issue

In an OpenShift cluster deployed via Installer-Provisioned Infrastructure (IPI) on VMware ESXi, nodes are not automatically labeled with individual ESXi host details. This limitation can impact workload anti-affinity rules intended to prevent two critical pods from being scheduled on the same physical host.

Environment

  • Red Hat OpenShift Container Platform 4.x
  • Installer-Provisioned Infrastructure (IPI)
