The version of Kubernetes used in Oracle CNE is based on the upstream Kubernetes project, and released under the CNCF Kubernetes Certified Conformance program. Oracle Container Host for Kubernetes (OCK) simplifies the configuration and set up of Kubernetes to create a Kubernetes cluster and includes backup. Kubernetes integrates with CRI-O to provide a comprehensive container and orchestration environment for the delivery of microservices and next-generation application development.

The core component in Oracle CNE is Kubernetes. Kubernetes includes:

• Flannel: The default overlay network for a Kubernetes cluster.

• CoreDNS: The DNS server for a Kubernetes cluster.

• CRI-O: Manages the container runtime for a Kubernetes cluster.

• runC: The default lightweight, portable container runtime for a Kubernetes cluster.

• Kata Containers: An optional lightweight virtual machine runtime for a Kubernetes cluster.
