This section is focused on integrating OpenNebula into modern DevOps and Infrastructure-as-Code (IaC) workflows using Kubernetes. It provides guides and reference material for extensions and plug-ins that enable users to manage and provision OpenNebula resources through external orchestration and configuration management frameworks, allowing for seamless automation of cloud infrastructure.

Kubernetes Cloud Provider: Documentation on the integration that allows Kubernetes to interact with OpenNebula, typically for provisioning infrastructure for Kubernetes clusters.

Kubernetes Cloud Provider

Mon, 19 May 2025 00:00:00 +0000

The Kubernetes Cloud-Provider Interface allows Kubernetes to interact with the underlying cloud infrastructure through the cluster-provider controller. This allows Kubernetes to manage cloud resources like nodes, load-balancers, etc.

OpenNebula offers its own Kubernetes cloud-provider implementation for providing nodes and load-balancers to Kubernetes clusters. You can find more information in the OpenNebula Cloud-Provider documentation.

Kubernetes Cluster API Integration

Mon, 17 Feb 2025 00:00:00 +0000

Kubernetes provides the Cluster API, a set of declarative APIs and tooling for simplifying and automating the provisioning, upgrading, deletion, and operation of multiple Kubernetes clusters in a declarative and extensible way, as if they were workloads of a management Kubernetes cluster.

OpenNebula provides its own implementation of the Cluster API (CAPONE) to easily provision and operate Kubernetes clusters. It interacts with OpenNebula for the provision of dedicated VMs (through the OpenNebula Cloud Provider) and to build the Kubernetes workload cluster, including the control plane nodes. You can find more information on the OpenNebula Cluster Api Provider wiki.

Kubernetes Container Storage Interface

The Container Storage Interface (CSI) is a standard designed to provide a uniform way for Container Orchestration (CO) systems like Kubernetes to expose arbitrary storage systems to their containerized workloads.

By de-coupling the storage plugin development from the core Kubernetes codebase, CSI allows storage vendors to develop, build, and deploy plugins as out-of-tree components, enabling faster innovation and easier maintenance without requiring upstream changes to the orchestrator itself.

CSI in OpenNebula

OpenNebula provides its own CSI Driver to allow Kubernetes Clusters running on OpenNebula resources to dynamically provision and manage persistent storage. This driver leverages OpenNebula’s native storage capabilities, enabling the following capabilities:
