Oracle is pleased to announce the general availability of Oracle Linux Cloud Native Environment Release 1.1. This release includes several new features for cluster management, updates to the existing Kubernetes module, and introduces new Helm and Istio modules.
Oracle Linux Cloud Native Environment is an integrated suite of software and tools for the development and management of cloud-native applications. Based on the Open Container Initiative (OCI) and Cloud Native Computing Foundation (CNCF) standards, Oracle Linux Cloud Native Environment delivers a simplified framework for installations, updates, upgrades, and configuration of key features for orchestrating microservices.
Several improvements and enhancements have been made to the installation and management of Oracle Linux Cloud Native Environment, including:
Oracle Linux Cloud Native Environment Release 1.1 includes Kubernetes Release 1.17.4. Please review the Release Notes for a list of the significant administrative and API changes between Kubernetes 1.14.8 and 1.17.
Helm is a package manager for Kubernetes that simplifies the task of deploying and managing software inside Kubernetes clusters. In this release, the Helm module is not supported for general use but is required and supported to deploy the Istio module.
Istio is a fully featured service mesh for deploying microservices into Kubernetes clusters. Istio can handle most aspects of microservice management, including identity, authentication, transport security, and metric scraping.
The Istio module includes embedded instances of the Prometheus monitoring and Grafana graphing tools which are automatically configured with specific dashboards to better understand Istio-managed workloads.
For more information about installing and using the Istio module, see Service Mesh.
Oracle Linux Cloud Native Environment is installed using packages from the Unbreakable Linux Network or the Oracle Linux yum server as well as container images from the Oracle Container Registry. Existing deployments can be upgraded in place using the olcnectl module update command.
