Advanced networking, Calico, and Kubernetes 1.25 in Oracle Cloud Native Environment 1.6
Oracle is pleased to announce the general availability of Oracle Cloud Native Environment Release 1.6, the scalable and highly available Kubernetes distribution that you can use to deploy your containerized applications across public clouds and on-premises.
This release includes Kubernetes 1.25, advanced networking virtualization and new technology preview modules. If you are running Kubernetes clusters across public clouds and on-premises, the enhanced cluster management features will make it much easier for you to manage your workloads by providing you a consistent view across all environments. Oracle Cloud Native Environment is an integrated suite of software components for the development and management of cloud native applications. Based on the Cloud Native Computing Foundation and Open Container Initiative standards, Oracle Cloud Native Environment delivers a simplified framework for installation, update, upgrade, and configuration of key features for orchestrating microservices through Kubernetes.
New features and enhancements
Oracle Cloud Native Environment 1.6 has many enhancements and new features including:
- Advanced networking support
- Calico 3.25.0 release: Calico is an open source networking and network security solution for containers, virtual machines, and native host-based workloads. Calico supports a range of platforms including Kubernetes. It provides developers and cluster operators with a consistent experience and set of capabilities whether running in a public cloud or on-premises, on a single node, or across multinode clusters.
- Multus 3.9.3 release: Multus CNI is a container network interface (CNI) plugin for Kubernetes that enables multiple network interfaces to be attached to pods. Typically, in Kubernetes each pod only has one network interface, with Multus you can create a multi-homed pod that has multiple interfaces.
- Kubernetes release 1.25.7, part of Oracle Linux Cloud Native Environment 1.6, obtained the CNCF Kubernetes Conformance certification. The Kubernetes Conformance test suite is a subset of e2e tests that SIG Architecture has approved to define the core set of interoperable features that all conformant Kubernetes clusters must support. The tests verify that the expected behavior works as a user might encounter it in the wild.
- Other updated components
- Istio is updated to 1.16.2 release
- Helm is updated to 3.11.1 release
- CRI-O is updated to 1.25.2 release

Technology Previews
The following features of Oracle Cloud Native Environment are under development, but are being made available to you as previews, for testing and evaluation purposes, only. These include:
- Kubevirt: KubeVirt technology addresses the needs of development teams that have adopted or want to adopt Kubernetes but possess existing Virtual Machine-based workloads that cannot be easily containerized. More specifically, the technology provides a unified development platform where developers can build, modify, and deploy applications residing in both application containers and virtual machines in a common, shared environment.
- Rook and Ceph: Rook orchestrates the Ceph storage solution, with a specialized Kubernetes Operator to automate management. Rook helps ensure that Ceph will run well on Kubernetes and helps simplify the deployment and management experience. Rook turns distributed storage systems into self-managing, self-scaling, self-healing storage services. It automates the tasks of a storage administrator, including deployment, bootstrapping, configuration, provisioning, scaling, upgrading, migration, disaster recovery, monitoring, and resource management.
Installation and upgrade
Oracle Cloud Native Environment is installed using packages from the Unbreakable Linux Network or the Oracle Linux yum server and container images from the Oracle Container Registry. Existing deployments can be upgraded in place using the `olcnectl module update` command.
