GKE provides a [validating and mutating webhook](https://github.com/GoogleCloudPlatform/ai-on-gke/tree/main/ray-on-gke/tpu/kuberay-tpu-webhook) to handle TPU Pod scheduling and bootstrap certain environment variables used for [JAX](https://github.com/google/jax) initialization. The Ray TPU webhook requires a KubeRay operator version of at least v1.1.0. GKE automatically installs the Ray TPU webhook through the [Ray Operator Addon](https://cloud.google.com/kubernetes-engine/docs/add-on/ray-on-gke/how-to/enable-ray-on-gke) with GKE versions 1.30.0-gke.1747000 or later.
