Oracle is pleased to announce the general availability of Oracle Cloud Native Environment Release 1.5. This release includes extended load-balancer capabilities, and enhanced security and compliance features that enable customers to have a virtually transparent experience when running Oracle Cloud Native Environment on-premises or on Oracle Cloud Infrastructure. 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.

New features and enhancements

The main enhancements in Oracle Cloud Native Environment 1.5 are focused on aspects of multicloud deployment including:

  • New "Metal Load Balancer - MetalLB" module, which is used to provide external IP addresses for Kubernetes applications running on bare metal hosts. MetalLB allows you to use Kubernetes LoadBalancer services, which traditionally make use of a cloud provider network load balancer, in a bare metal environment.
  • Improved Oracle Cloud Infrastructure Cloud Controller Manager module, has been extended to manage load balancers to provide external IP addresses for Kubernetes applications in a Kubernetes cluster running on Oracle Cloud Infrastructure instances.
  • New compact Kubernetes clusters, single-node deployment option for developers and proof of conceptenvironments.
  • Improved log messages in Platform API Server and Platform Agent
  • The Kubernetes release 1.22, part of Oracle Linux Cloud Native Environment 1.5, 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.
  • Updated components
    • Kubernetes is updated to 1.22.8 release
    • Istio is updated to 1.13.2 release
    • CRI-O is updated to 1.22.3 release
