Unable to create a LoadBalancer service for Tanzu for Valkey on Kubernetes

Products

• VMware Tanzu for Valkey

Issue/Introduction

When attempting to apply or create a Valkey custom resource instance using kubectl apply -f, the deployment fails with the following strict decoding error:

Error from server (BadRequest): error when creating "valkey-instance.yaml": Valkey in version "v1" cannot be handled as a Valkey: strict decoding error: unknown field "spec.kubernetesConfig.service"

Environment

Tanzu for Valkey on Kubernetes

Cause

The custom resource definition (CRD) schema for [data.tanzu.vmware.com/v1](https://data.tanzu.vmware.com/v1) expects the Kubernetes service type to be declared via the field spec.kubernetesConfig.serviceType.

Using the nested block structure spec.kubernetesConfig.service.type causes a strict YAML decoding failure because the field service is not recognized by the Tanzu for Valkey Operator schema.

Resolution

Update the Valkey manifest YAML to define serviceType directly under spec.kubernetesConfig.

apiVersion: data.tanzu.vmware.com/v1
kind: Valkey
metadata:
  name: valkey-sample
  namespace: <your-namespace>
spec:
  valkeyVersion:
    name: valkey-9.1.0
  kubernetesConfig:
    serviceType: LoadBalancer   # Correct property syntax
