KubeRay Joins CNCF, Completing Linux Foundation Governance for the PARK Stack
KubeRay has officially joined the Cloud Native Computing Foundation (CNCF), placing the entire PyTorch, AI models, Ray, and Kubernetes (PARK) stack under neutral Linux Foundation governance.
On November 9, 2026, the open-source project KubeRay announced its donation to the Cloud Native Computing Foundation (CNCF). This move places the entire “PARK” technology stack—comprising PyTorch, AI models, Ray, and Kubernetes—under the governance of the Linux Foundation, aiming to provide enterprises adopting this open-source AI infrastructure with a guarantee of neutrality.
KubeRay is a toolkit and operator designed to run distributed AI, machine learning, and Python workloads on Kubernetes. Previously, core components of the PARK stack were already managed by different organizations under the Linux Foundation umbrella: PyTorch and Ray through the PyTorch Foundation, and Kubernetes through the CNCF. The addition of KubeRay fills the final gap.
In a blog post, Anyscale stated that as distributed AI workloads become a core cloud-native construct, KubeRay bridges the gap between Python-first AI frameworks and Kubernetes-native infrastructure. The transfer to a CNCF sandbox project marks the beginning of a new chapter for the project under open, vendor-neutral governance.
