Workarounds

  1. 95% success Update the apiVersion in your manifests to the current served version

  2. 88% success Use kubectl convert to migrate manifests: kubectl convert -f old.yaml --output-version apps/v1 
    kubectl convert -f old.yaml --output-version apps/v1

    Sources: https://kubernetes.io/docs/tasks/tools/install-kubectl-linux/

Dead Ends

Common approaches that don't work:

  1. Downgrade the cluster 85% fail

    Dangerous and loses features from newer versions

  2. Force apply with --validate=false 80% fail

    Bypasses validation but API server still rejects the version
