Environment

@zhaotyer x-kubernetes-validations is a structural schema validation extension introduced in Kubernetes v1.23 as an alpha feature and graduated to beta in v1.25.

What you can do for short term workaround is to remove x-kubernetes-validations field in the yaml and retry it

We will consider to provide a cleaner version soon.

For LWS, https://github.com/kubernetes-sigs/lws/blob/main/site/content/en/docs/troubleshooting/_index.md suggest upgrading the Kubernetes cluster to v1.26+ for feature gate StatefulSetStartOrdinal.

• Edited: my fault, I thought AIBrix is using LWS. It seems not. 😅

For Kubernetes Community, https://endoflife.date/kubernetes 1.30+ would be suggested and https://github.com/kubernetes/community/tree/master/wg-lts may have some updates on official suppoted versions later.
