Cluster Operations Overview

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

OpenNebula’s Cloud Cluster Operations are used to manage Providers and Provisions. Provider management deals with maintaining the external resources that OpenNebula uses to build and manage Clusters. Provision management involves the core functionality of deploying and managing Cluster instances using the defined Providers.

Basic Outline

This guide consists of two sections:

Managing Providers: Use OneForm to define, instantiate and configure your deployments.
Managing Provisions: Dynamically grow your cloud infrastructure automatically on remote cloud providers or on-premises resources.

Hypervisor Compatibility

Cloud Cluster Operations are compatible with KVM hypervisors.

Managing Providers

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

In OneForm, Providers are created using Provider drivers for on-premise hardware or 3rd-party cloud/bare-metal services such as AWS, Scaleway and Equinix. Use the oneform CLI tool to manage your cloud infrastructure instance and configuration.

With this guide, you will understand how the drivers and Providers and Provisions relate by:

Enabling and disabling cloud drivers.
Managing access controls

Important

All driver information is securely stored and encrypted. While regular users can list and view driver information, only members of the oneadmin group are allowed to manage and modify Providers.

Enabling a OneForm Driver

To use a new cloud driver, enable it using the oneform enable command. This validates all the information about the driver and allows users to create Providers and Provisions based on the driver.

Managing Provisions

In OneForm, Provisions represent fully-deployed Clusters or infrastructure stacks. Each Provision is associated with a specific cloud or on-premises Provider and contains OpenNebula resources such as Hosts, datastores, and Virtual Networks.
