Meaning

Some fields are immutable because changing them would orphan or confuse existing objects. The fix is to delete and recreate the object (or create a new one with a different name). Helm upgrades fail this way when chart labels change.

Common causes

  • Changing spec.selector (labels) of a Deployment/StatefulSet
  • Editing a completed Job’s template
  • Changing PVC storageClassName/size down, Service clusterIP or type-specific fields

⚡ Quick fix

  1. Delete and recreate the object (keep data volumes in mind)
  2. Create it under a new name and switch traffic
  3. For Helm, keep selector labels stable

Detailed fix by platform

Kubernetes

  1. bash
    kubectl delete deployment web --cascade=orphan   # keep pods running
kubectl apply -f deployment.yaml

How to diagnose

  1. Field — Which path is named?
  2. Diff — kubectl diff -f file.yaml
