Openstack Ironic

OpenStack Ironic is an open-source bare metal provisioning service (infrastructure orchestration) that provisions and manages physical machines using standard cloud APIs as part of the OpenStack ecosystem.

  • Bare metal provisioning and lifecycle management for physical servers (infrastructure orchestration).
  • Integration with OpenStack services such as Nova for instance scheduling on bare metal (cloud infrastructure).
  • Support for multiple hardware drivers and Out-of-Band Management (OOB) interfaces like IPMI and Redfish (hardware management).
  • Network and storage integration for provisioning flows via pluggable drivers and OpenStack networking components (infrastructure integration).
  • API-driven management of enrollment, inspection, cleaning, deployment, and retirement of physical nodes (infrastructure automation).

More About Openstack Ironic

OpenStack Ironic is a bare metal provisioning service (infrastructure orchestration) within the OpenStack cloud platform that enables users to deploy workloads directly onto physical servers instead of virtual machines. It addresses use cases where applications require direct access to hardware resources, predictable performance, or specific hardware features that are not exposed through virtualization layers.

Ironic exposes a programmable Application Programming Interface (API) (infrastructure automation) that manages the full lifecycle of physical nodes, including enrollment, hardware inspection, cleaning, image deployment, and decommissioning. It controls bare metal machines through OOB protocols (hardware management) such as IPMI and Redfish, and through vendor-specific drivers where supported by the project. This driver-based architecture allows Ironic to interact with a range of server platforms and management controllers without embedding hardware-specific logic into the core service.

Within an OpenStack deployment, Ironic integrates with the Nova compute service (cloud infrastructure) so that Nova can schedule instances onto bare metal nodes in a similar manner to virtual machines. From the user’s perspective, instances running on bare metal can be requested through familiar OpenStack APIs, images, and quotas, while Ironic handles the low-level provisioning workflow, including network boot, disk imaging, and power control.

Ironic also connects with OpenStack networking and storage components (infrastructure integration), typically Neutron for network configuration and various image services for boot images. Network isolation, tenant networks, and provisioning networks can be managed using these integrations, enabling multi-tenant bare metal environments. The project uses a pluggable driver model for network and storage interactions, allowing operators to integrate with different switches, Software Defined Networking (SDN) controllers, and storage backends where supported.

In enterprise and institutional environments, Ironic is used to build private or hosted bare metal clouds (cloud infrastructure) that provide API-driven access to physical servers for High performance computing (HPC), data-intensive workloads, Network Functions Virtualization (NFV), and hardware-dependent applications. Operators can manage mixed fleets of physical and virtual infrastructure under a single OpenStack control plane, using consistent authentication, quota, and governance models.

From a directory and taxonomy perspective, OpenStack Ironic fits in categories such as bare metal provisioning, infrastructure orchestration, and cloud infrastructure management. It operates as part of the OpenStack control plane but can also be deployed in scenarios focused primarily on physical server automation, where its API-centric approach to hardware lifecycle management is relevant for Data Center Operations (DCO) and infrastructure engineering teams.
