The Oracle Linux team is pleased to announce the general availability of Oracle Cloud Native Environment Release 1.8, the scalable and highly available Kubernetes distribution that can be used to deploy your containerized applications across public clouds and on-premises.

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 the installation, update, upgrade, and configuration of key features for orchestrating microservices through Kubernetes.

This release includes Kubernetes 1.28 and introduces support for the latest Oracle Linux 8 and Oracle Linux 9 releases on x86_64 and aarch64 architectures. If you are running Kubernetes clusters across public clouds and on-premises, the enhanced cluster management features—including the ability to have a consistent view across all environments—canmake it much easier for you to manage your workloads. 

New features and enhancements

Oracle Cloud Native Environment 1.8 includes:

  • Support for deployment on hardware with 64-bit ARM processors.
    • With this release, mixed processor types x864-64 and aarch64 are supported in a Kubernetes cluster. The processor type is automatically detected during installation; no extra steps are required.  
  • Logs for long running commands.
    • A new set of commands to view logs for long-running Platform CLI commands. This allows logs to be viewed for all existing operations, the ability to follow the logs of ongoing operations, and the ability to view the log of a completed operation.
  • CNCF Kubernetes Conformance certification, as part of Kubernetes 1.28.
    • The Certified Kubernetes Conformance Program 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.     
  • For a full list of individual software component versions included with this release, please review the Oracle Cloud Native Environment Release Notes.

New tutorial to deploy Kubernetes on Oracle Cloud Infrastructure

Oracle Cloud Native Environment provides an option to deploy Kubernetes on-premises and on the cloud. 

This tutorial will teach you, step-by-step, how to set up Oracle Cloud Native Environment on Oracle Cloud Infrastructure (OCI). No experience with OCI is required to complete the tutorial, and you will have an installation of the latest version of Oracle Cloud Native Environment running on a highly available cluster hosted on OCI in approximately two hours.

NGINX Ingress Controller available as a technology preview

The NGINX Ingress Controller plays key roles for Kubernetes. The controller, in fact, accepts the traffic coming from outside the Kubernetes cluster and load balances it so it can reach the various containers within your platform.

The NGINX Ingress Controller also manages the egress traffic present within a cluster for services that may all need to communicate with an external service. The controller is also capable of automatically revising the load-balancing rules whenever you add or remove containers from a particular service.

Oracle Cloud Native Environment 1.8 introduces the availability of NGINX Ingress Controller as a technology preview. This technology preview allows customers, partners (ISV and IHV), and community users to test the NGINX Ingress Controller with Oracle Cloud Native Environment 1.8.

Note: The Oracle Cloud Native Environment 1.8 NGINX Ingress Controller should not be used in a production environment.

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.

You can install Oracle Cloud Native Environment by following the instructions in the getting started guide. You can also update Oracle Cloud Native Environment by following the updates and upgrades guide.

Support for Oracle Cloud Native Environment

Support for Oracle Cloud Native Environment is included with an Oracle Linux Premier Support subscription.

Oracle Linux Premier Support is included with Oracle Cloud Infrastructure subscriptions and Oracle Premier Support for Systems at no additional cost.
